Abstract:
Damage scenarios are necessary tools for stakeholders, in order to prepare protection strategies and a total emergency post-earthquake plan. To this aim, four seismic hazard models were developed for the city of Kalamata, according to stochastic simulation of the ground motion, using site amplification functions derived from ambient noise HVSR measurements. The structural vulnerability of the city was assessed following an empirical macroseismic model, developed for the European urban environment (EMS-98). The impact of the vulnerability due to the seismic hazard potential is also investigated by means of synthetic response spectral ratios at 108 sites of the city. The expected damage grade per building block, is calculated by combining vulnerability with the respective seismic intensities, derived for the four seismic sources. The importance of the followed methodology for implementing microzonation studies is emphasized, since the expected influence of the ground motion amplification due to local soil conditions has been approximated in detail. Moreover, new fragility curves for the main structural types in Kalamata are proposed for each seismic scenario.

Abstract:
The vulnerability of bridges and the effectiveness of suitable mitigation techniques in regions exposed to different seismic scenarios, while lacking reliable fragility assessment studies for existing bridge inventory, need focused attention. Further, while several retrofit techniques were proposed for improving the seismic performance of existing bridges, the limitations of such approaches need further investigation. Thus, this study assesses the seismic vulnerability of a benchmark structure representing pre-seismic code multi-span bridges in an earthquake-prone region before and after the retrofit to mitigate earthquake-related losses. The numerical modeling approaches of the selected bridge and retrofit systems were verified using the results of previous experimental studies. Detailed three-dimensional fiber-based (3DFB) simulation models were then developed to assess the seismic response of the benchmark bridge under the effects of diverse earthquake records representing far-field and near-source seismic scenarios in both longitudinal and transverse directions. The obtained results from several inelastic pushover analyses (IPAs) and incremental dynamic analyses (IDAs) confirmed the vulnerability of the benchmark bridge and the pressing need for mitigation actions to reduce the expected seismic losses under different seismic scenarios. Higher damage probabilities were observed under the effects of far-source events and at lower intensities than their near-field counterparts. Based on the probabilistic assessment study, it is concluded that retrofitting the bridge with buckling restrained braces (BRBs) is an effective mitigation measure to increase the lateral strength and overcome the high curvature ductility (CD) demands observed in bents, particularly under the most critical seismic scenario. The study provides insight into the impacts of contemporary retrofit techniques on improving the seismic performance of substandard bridges and presents a range of fragility functions for the assessment and mitigation of earthquake risks.

Abstract:
Pile-supported wharf (PSW) is one of the primary port structures and is often damaged by earthquakes. To mitigate the risk of seismic damage to a PSW, its seismic performance should be thoroughly assessed. This study aimed to examine the impact of ground displacement on the seismic performance of PSW with a mild soil slope. We performed soil-structure system finite element analysis targeting a wide PSW. The analysis is divided into two scenarios. In the first scenario, the PSW was modeled without regard for the soil slope, whereas the second scenario considered the soil slope. Two waveforms that matched the target spectral acceleration were used to study the effects of the waveform duration on the seismic response of PSW. The analysis results revealed substantial influences of soil slope displacement as well as differences in waveforms on PSW’s seismic performance.

Abstract:
A large part of the European building stock was built before implementing the recent energy and structural codes, resulting in buildings characterized by deficiencies in terms of comfort, energy savings and structural safety. The retrofitting and rehabilitation of the existing building stock need to be adequately performed, aiming to improve the seismic and energy performance simultaneously. The work summarized here is dedicated to defining priority scenarios for buildings’ retrofitting to improve the seismic safety and energy efficiency of the European Union (EU) building stock. First, the state of the EU building stock is analysed in terms of buildings’ age, types of structures, energy efficiency, energy consumption and energy poverty. Then, the EU climate demands are presented, namely the regions with higher temperature variations, i.e., heating or cooling degree days. The EU seismic risk is also presented and discussed in terms of average annual losses, average annual economic losses and average annual life losses. Based on these input parameters, nine seismic–climate regions in the EU are proposed using a simplified approach. Finally, retrofitting scenarios are proposed for two types of buildings (i.e., masonry and reinforced concrete) based on their seismic–climate region.

Abstract:
A methodology for simulating seismic damage of unreinforced masonry buildings for seismic risk assessment of urban areas is presented in this paper. The methodology is based on the Italian vulnerability index and on the results of a post-earthquake damage survey study whose main result was an observed vulnerability function. The Monte Carlo method was then used to simulate damage probability matrices, fragility curves and vulnerability functions, all of which are the basis of a seismic risk study. The simulation process required the generation of thousands of hypothetical buildings, the analysis of their seismic behaviour and probabilistic studies of the computed results. As an example, probable damage scenarios were developed for an urban zone of Barcelona.

Abstract:
A seismic hazard assessment was carried out for the Catania and Siracusa towns providing a comprehensive re-examination and re-processing of all the available seismic data. The site approach and the seismotectonic one were used and compared. The hazard assessment, using both methods, was performed following a logic-tree approach in order to consider and reduce the epistemic uncertainties. The combined use and comparison of these approaches is recommended since it allows to verify the robustness of the hazard estimates and allowed us to obtain useful elements to define the seismic hazard in Catania and Siracusa. Experimental data and numerical modeling were used to study the effect of local geology on the seismic response in the Catania area. Available boreholes data and elastic parameters were used to reconstruct a geotechnical model in order to perform 1D numerical modeling. Seismic urban scenarios were simulated considering destructive (Mw=7.0), strong (Mw=6.2) and moderate (Mw=5.7) earthquakes. PGA and spectral acceleration at different periods were obtained in the urban area through the equivalent linear numerical code EERA, and contour maps of different levels of shaking were drawn. Standard and horizontal-to-vertical spectral ratios were achieved making use of a dataset of 172 seismic events recorded at ten stations located on the main outcropping lithotypes. Spectral ratios inferred from earthquake data were compared with theoretical transfer functions. Both experimental and numerical results confirm the role of the geologic and morphologic setting of Catania. A study aimed to investigate on the dynamic properties of main lithotypes outcropping in the Siracusa area and their relationships with the local seismic response was performed. Non-invasive seismic prospecting techniques using the vertical component of surface waves (MASW and ReMi) were adopted, as well as ambient noise measurements, processed through the Nakamura technique. Moreover, a cluster analysis was performed to subdivide into homogeneous groups the experimentally obtained noise spectral ratios. Results pointed out that the use of combined different methods provides a more robust way to characterized the investigated soils and to reduce the problems linked to the non-uniqueness of solutions during the interpretation of geophysical data. The role of local geology and topography on the site response of a small hill, located in the northern part of Catania, was investigated. Ambient noise and earthquake data were processed through standard and horizontal-to-vertical spectral ratios. Directional effects were also investigated by computing the spectral ratios after rotating the horizontal components of motion and performing polarization analysis. Results of noise and earthquakes analysis, although show significant differences in amplitude, are comparable in frequency, especially in the sedimentary terrains. Pronounced directional effects are mostly observed on the slopes rather than at the hill top. Our findings appear linked to the complex wavefield generated by the lithologic heterogeneities existing in the area which seem to have a stronger influence with respect to the simple topographic effect. Seismic noise recorded by mobile stations in the Ortigia peninsula (downtown Siracusa) was analyzed through H/V spectral ratios, to investigate local site effects. Moreover, shear wave velocities were investigated through non-invasive techniques (MASW and ReMi) in order to assess the theoretical resonant frequency of the hill. Experimental results coming out from the spectral ratios show peaks in the frequency range 1.0-3.0 Hz which are consistent with the theoretical resonance frequency at Ortigia. The H/V azimuthal spectral analysis shows a clearly predominant E-W directional effect, transversal to the main axis of the peninsula, which is also confirmed by the polarization analysis in the time domain.

Abstract:
Este trabajo presenta un estudio de riesgo sísmico para los edificios de Mérida, Venezuela. Consiste en una evaluación de la amenaza y de la vulnerabilidad sísmicas para toda la ciudad y en un estudio más detallado de la vulnerabilidad de viviendas de autoconstrucción en el Barrio de "La Milagrosa".
Se describe la ciudad de Mérida y su evolución durante sus más de 400 años de historia. Se lleva a cabo una evaluación de su peligrosidad sísmica. El marco tectónico así como las zonas sismogenéticas se toman de otros estudios. Se efectúa un análisis probabilístico no zonificado, obteniendo los períodos de retorno y las probabilidades anuales de excedencia de terremotos de grado I = VI a I = IX según la Escala Macrosísmica Europea. Las aceleraciones máximas horizontales para estos eventos se estiman mediante una ley de atenuación deducida especialmente para el oeste de Venezuela. Estas aceleraciones se utilizan para efectuar una serie representativa de análisis de la respuesta (en la meseta). Los períodos máximos obtenidos así como los correspondientes factores de amplificación se utilizan para realizar una Microzonificación de dicha meseta. Los efectos inducidos (licuefacción y deslizamientos) se estiman mediante la metodología de estimación de pérdidas sísmicas HAZUS®.
Se utilizan dos metodologías de evaluación de la vulnerabilidad: IVIM y LM1. LM1 proporciona distribuciones de vulnerabilidad para Mérida; éstas permiten concluir de manera preliminar que la mayor parte de las construcciones de "La Milagrosa" (y de otros asentamientos informales) son altamente vulnerables. IVIM se utiliza para llevar a cabo una evaluación más detallada de la vulnerabilidad de estas construcciones; la información sobre éstas se adquiere estudiando los informes de daños para situaciones similares, intentando comprender su comportamiento frente a acciones sísmicas y efectuando un análisis de tres edificios prototipo (de una, dos y tres plantas) según la normativa sismorresistente Venezolana. La evaluación por la metodología IVIM permite clasificar a las construcciones según sus índices de vulnerabilidad. Esta información se utiliza para efectuar un nuevo estudio dentro de "La Milagrosa" (con la metodología LM1) para obtener escenarios de daño.
Se proponen soluciones preliminares para construcción sismorresistente de nuevos edificios y para acondicionamiento de edificios existentes. Se incluye un balance económico coste-beneficio.
Se presentan escenarios globales de daño obtenidos con la metodología LM1. El sistema de información geográfica ArcView® utilizado en esta investigación proporciona distintas maneras de presentar la información disponible. La distribución del daño en la ciudad se ilustra especialmente mediante los distintos grados de daño (para las intensidades escenario) como porcentaje de los edificios en los subsectores.
This work presents a seismic risk assessment on the buildings of Mérida, Venezuela. It consists of a global hazard and vulnerability evaluation and a deeper vulnerability analysis for non-engineered constructions at the "La Milagrosa" settlement.
The city of Mérida and its physical evolution throughout more than 400 years is described. A seismic hazard assessment is performed. The tectonic framework as well as the seismogenic zones are taken from other studies. A non-zonified probabilistic analysis is performed obtaining the return periods and annual exceedance probabilities for events corresponding to the European Macroseismic Scale intensity degrees from I = VI to I = IX. The expected horizontal PGAs for these events are estimated by means of a specially derived attenuation law for western Venezuela. These accelerations are used for a number of representative site response analyses (in the plateau). The obtained maximum amplification periods and the corresponding amplification factors are used to carry out a microzonation of the Mérida plateau. Possible induced effects such as liquefaction and landsliding are estimated by the HAZUS® Earthquake Loss Estimation Methodology.
Two vulnerability assessment methodologies (IVIM and LM1) are used. LM1 provides vulnerability distributions for Mérida; they allow preliminarily concluding that most of the constructions at "La Milagrosa" (and other informal settlements) are highly vulnerable. IVIM is used to perform a more detailed vulnerability evaluation of these constructions; the required knowledge about them is acquired by studying the available damage reports for similar situations, by trying to understand their seismic behavior and by performing a code type analysis (following Venezuelan regulations) on three prototype buildings (with one, two and three floors, respectively). The output of the evaluation by the IVIM is a classification of the constructions according their vulnerability indices. This information is used to perform a new study inside "La Milagrosa" with LM1 methodology providing local damage scenarios.
Preliminary solutions for earthquake resistant construction of new buildings and for seismic strengthening of existing ones are proposed. A Cost-Benefit analysis is presented.
Global damage scenarios obtained by the LM1 method are presented. Several manners to display this information are available through the GIS ArcView® software used in this research; the distribution of the different damage grades occurring at the scenario intensities as a percentage of the total number of buildings in the sub-sectors, is primarily used to display the damage distribution in the city.

En tant que géoscientifique dans le domaine de l’Exploration pétrolière et gazière depuis une vingtaine d’années, mes fonctions professionnelles m’ont permis d’effectuer différents travaux de recherche sur la thématique de la gestion des risques et des incertitudes. Ces travaux de recherche se situent sur l’ensemble de la chaîne d’analyse Exploration, traitant de problématiques liées à l’acquisition et au traitement sismique, jusqu’au placement optimal de forages d’exploration. Un volet plus poussé de mes travaux s’est orienté sur la gestion des incertitudes géophysiques en Exploration pétrolière, là où l’incertitude est la plus importante et paradoxalement la moins travaillée.On peut regrouper mes travaux de recherche en trois grands domaines qui suivent les grandes étapes du processus Exploration : le traitement sismique, leur interprétation, et enfin l'analyse et l'extraction des différentes incertitudes qui vont nous permettre de calculer les volumes d’hydrocarbures en place et récupérables, ainsi que l’analyse de ses risques associés. L’ensemble des travaux de recherche ont été appliqués avec succès sur des cas d’études opérationnelles. Après avoir introduit quelques notions générales et détaillé les grandes étapes du processus Exploration et leur lien direct avec ces problématiques, je présenterai quatre grands projets de recherche sur un cas d’étude algérien
In the last 20 years, I have been conducting various research projects focused on the management of risks and uncertainties in the petroleum exploration domain. The various research projects detailed in this thesis are dealing with problematics located throughout the whole Exploration and Production chain, from seismic acquisition and processing, until the optimal exploration to development wells placement. Focus is made on geophysical risks and uncertainties, where these problematics are the most pronounced and paradoxically the less worked in the industry. We can subdivide my research projects into tree main axes, which are following the hydrocarbon exploration process, namely: seismic processing, seismic interpretation thanks to the integration with various well informations, and eventually the analysis and extraction of key uncertainties, which will be the basis for the optimal calculation of in place and recoverable volumes, in addition to the associated risk analysis on a given target structure. The various research projects that are detailed in this thesis have been applied successfully on operational North Africa and North Sea projects. After introducing risks and uncertainty notions, we will detail the exploration process and the key links with these issues. I will then present four major research projects with their theoretical aspects and applied case study on an Algerian asset

Abstract:
Recent earthquakes have highlighted that the consideration of isolated seismic events, although necessary, may not be sufficient to prevent building collapse. In fact, the occurrence of a large number of aftershocks with significant intensity, as well as the occurrence of tsunamis, fires, and explosions, poses a safety threat that has not been addressed properly in the design and assessment of building structures over the last decade. Although research has been developed in order to evaluate the impact of multiple and/or cascading hazards in structural safety and economical losses, there is no established framework to perform such analysis. In addition, the available numerical tools lack a unified implementation in a widely used software in order to allow for the development of large numerical simulations involving these hazard events. This work proposes a probabilistic framework for quantifying the robustness of structures considering the occurrence of a major earthquake (mainshock) and the subsequent cascading hazard events, namely fire and aftershocks. These events can significantly increase the probability of collapse of buildings, especially for structures that are damaged during the mainshock. In order to assess the structural performance under post-earthquake hazards, it is of paramount importance to accurately simulate the damage attained during the earthquake, which is strongly correlated to the residual structural capacity to withstand cascading events. In this context, the influence of ground motion characteristics, namely ground motion duration, has been identified as one of the parameters that may induce significant bias on damage patterns associated with the mainshock. Thus, ground motion duration influence on structural damage is analyzed in this work. Steel moment resisting frame buildings designed according to pre-Northridge codes are analyzed using the proposed framework. These buildings are representative of the design practice in the US and Europe for decades, and the conclusions of this work can be significant in the assessment/retrofit of thousands of buildings. Fragility curves and reliabilitybased robustness measures are obtained using the proposed framework. The fragility curve parameters obtained herein can be used in the development of future probabilistic-based studies considering post-earthquake hazards. The results highlight the importance of the post-earthquake hazard events in the structural safety assessment. Further work is needed in order to better characterize these hazards as to include them in the code-based design and assessment methodologies.

Abstract:
AbstractRecent devastating earthquakes outlined the importance of quantifying losses and the amount of resources needed for the reconstruction process. The restoration of public or residential buildings in the aftermath of the seismic event may significantly affect national economy. This remarks the primary role and crucial need of having accurate predictions of direct and indirect costs for reconstruction in order to plan effective risk mitigation strategies and perform reliable loss scenarios. The recent Italian seismic events have been a unique occasion to collect observational data on existing buildings. The present work, based on the Italian experience of recent earthquakes, aims at discussing the main aspects related to the damage assessment of residential buildings and reconstruction models together with the huge amount of data collected in the reconstruction processes. In particular, an in-depth analysis of the data provided by the reconstruction process of 2009 L’Aquila earthquake is reported focussing on repair and strengthening intervention costs as a function of the empirical damage,repairability issues, and assistance to population costs. The data are discussed separately for reinforced concrete and masonry residential buildings and refers about 10,100 buildings located Outside Historical Centres (OHC) and Inside Historical Centres (IHC). Finally, the criteria adopted for the definition of the building seismic risk classes at the base of the Italian guidelines for seismic risk classification of constructions are presented together with recent policies adopted in Italy in terms of fiscal deduction for strengthening interventions on private residential buildings.

Abstract:
In the present study deterministic earthquake scenarios for the city of Varna - the thirdlargest city in Bulgaria are presented. By deterministic scenario, it is mean a representation of the severity of ground shaking over an urban area, using one or more hazard descriptors. The assessment of seismic hazard and generation of earthquake scenarios is the first step of seismic risk evaluation and society prevention. Seismic history of Varna shows that the hazard for the city is mainly influence by the earthquakes occurred in the seismogenic zone Shabla (Kaliakra fault system). The local ground shaking levels are computed using the six ground motion prediction equations (GMPE�s) for tectonically active regions that are previously selected. A reliable geotechnical zonation of the city of Varna was incorporated in the earthquake scenario generation. Deterministic ground shaking scenarios for the city of Varna are generated for two scenario earthquakes with different location and magnitudes are considered. The generated scenarios are described in terms of MSK (=EMS98) intensity, peak ground acceleration and velocity and in spectral accelerations for Sa (0.3s) and Sa (1.0s). The results in PGA and MSK intensity for scenario MW7.2 quake located on strike slip Kaliakra fault are mapped. The estimated peak ground accelerations for MW7.2 quake vary between 0.07 and 0.14 g.

Abstract:
<p>The Modified Monolithic Beam Analogy (MMBA) is a method for the analytical modelling of controlled rocking connections by establishing a displacement equivalence between the rocking member and an equivalent monolithic member. As member displacement is a function of the applied loads, the MBA must formulated for each loading scenario. The MMBA is extended to loadings scenarios with simultaneous seismic and gravity actions. This formulation can be used to analyse and design controlled rocking connections under combined seismic-gravity actions. The difference in connection response between seismic-only and combined seismic-gravity loadings is exemplified and the design implications for frames under this combined loading case is discussed.</p>

Abstract:
The Korea Atomic Energy Research Institute (KAERI) and Brookhaven National Laboratory (BNL) are continuing a collaborative effort to achieve a better understanding of the effects of aging on the performance of structures and passive components (SPCs) in nuclear power plants (NPPs). This paper presents a seismic fragility analysis of a condensate storage tank (CST) with multiple degradation scenarios that are treated in a non-perfectly correlated manner. The analysis utilizes a set of optimum Latin Hypercube samples to characterize the deterioration behavior of the fragility capacity as a function of age-related degradations. This study is an addition to the previous study summarized in an ICONE19 paper entitled “Seismic Fragility Analysis of a Degraded Condensate Storage Tank” [1], which considered individual degradation scenarios and multiple degradations occurring in a perfectly correlated manner.

Abstract:
Southwest British Columbia has some of the highest seismic hazard in Canada and is home to facilities owned by the Department of National Defence which support operations on the west coast of Canada. The potential impact of seismic hazards on these government facilities are investigated here. The hazard is from three primary sources: subduction interface, crustal and in-slab earthquakes. NRCan, in consultation with DRDC have produced representative earthquake scenarios for each of these sources. The subduction scenario we constructed was an M8.9 earthquake extending along the entire Cascadia Subduction Zone from 4 to 18 km depth. We used an M6.8 earthquake occurring along a 30 km fault at between 52 and 60 km depth below Boundary Bay to represent in-slab events. The final scenario, representing a crustal source, was an M6.4 along the central 47 km of the Leech River Valley-Devil's Mountain Fault system. We found that the Cascadia subduction scenario dominated the shaking hazard over much of the study region. Meanwhile, the in-slab and crustal scenarios have higher but more localized hazards in Vancouver and Victoria. In addition to the primary ground motion hazard, we also examined secondary seismic hazards: secondary amplification effects, landslides, liquefaction, surface ruptures, tsunami, flooding, fire, and aftershocks. Each of the secondary hazards had varying impacts depending on the scenario and locations within the region.

Abstract:
The Geological Survey of Canada conducted a broad regional study of the Magdalen Basin in the Gulf of St. Lawrence, as part of the Marine Conservation Targets initiative. MCT is a national initiative to protect more of Canada's offshore areas, and resource assessment and related regional mapping are part of the review process. This study assembled a large seismic and geologic database that allowed new regional mapping of several key horizons in this basin. Digital seismic data was donated by industry, and reprocessing undertaken both in-house and with contractors. Wells were correlated and tops from literature were used to indentify regional reflection packages. Regionally consistent two-way time interpretations add to confidence. Depth conversion used regional time-depth functions from literature, which were developed from refraction data, with a residual correction for the water column. Nine regional depth maps and eight isopach maps were produced, including Pre-Horton Basement, Horton Group Isopach, Base Windsor Group, Top Salt, Top Bradelle Formation, Bradelle / Cumberland Isopach, and Top Cable Head Formation. These maps illustrate that the Pre-Horton basement is about 15 km deep in the centre of the basin. Two main trends are visible in the Horton Grabens, which may relate to basin formation, and no significant reactivation of deeper Appalachian structure is observed. In the basin centre, the more robust Base Windsor Unconformity horizon reaches about 12 km deep, and a key reservoir and source sequence in the Bradelle Formation reaches 7 km. These maps are useful for considering regional stratigraphy. The new mapping also constrained basin models and became the input for our Qualitative Petroleum Potential map. Basin modelling reveals scenarios where oil may be preserved. The petroleum potential of the region is highest north of Îles de la Madeleine and southeast of Îles de la Madeleine and northwest of Cape Breton.

Full text
Abstract:
Natural Resources Canada, in partnership with the Global Earthquake Model Foundation, has prepared a public Canadian Seismic Risk Model to support disaster risk reduction efforts across industry and all levels of government, and to aid in Canada's adoption of the Sendai Framework for Disaster Risk Reduction. Developing this model has involved the creation of a national exposure inventory, Canadian specific fragility and vulnerability curves, and adjustment of the Canadian Seismic Hazard Model which forms the basis for the seismic provisions of the National Building Code of Canada. Using the Global Earthquake Model Foundation's OpenQuake Engine (OQ), risk modelling is completed using both deterministic and probabilistic risk calculations, under baseline and simulated retrofit conditions. Output results are available in all settled regions of Canada, at the scale of a neighbourhood or smaller. We report on expected shaking damage to buildings, financial losses, fatalities, and other impacts such as housing disruption and the generation of debris. This paper documents the technical details of the modelling approach including a description of novel datasets in use, as well as preliminary results for a magnitude 9.0 earthquake on the Cascadia megathrust and nation-wide 500 year expected probabilistic losses. These kinds of results, such as earthquake scenario impacts, loss exceedance curves, and annual average losses, provide a quantitative base of evidence for decision making at local, regional, and national levels.

CAPACITY EVALUATION OF EIGHT BOLT EXTENDED ENDPLATE MOMENT CONNECTIONS SUBJECTED TO COLUMN REMOVAL SCENARIO. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.6.

Full text
Abstract:
The extended stiffened endplate (8ES) connection is broadly used in the seismic load-resisting parts of steel structures. This connection is prequalified based on the AISC 358 standard, especially for seismic regions. To study this connection’s behaviors, in the event of accidental loss of a column, the finite element model results were verified against the available experimental data. A parametric study using the finite element method was then carried out to investigate these numerical models’ maximum capacity and effective parameters' effect on their maximum capacity in a column loss scenario. This parametric analysis demonstrated that these connections fail at the large displacement due to the catenary action mode at the rib stiffener's vicinity. The carrying capacity, PEEQ, Von-Mises stress, middle column force-displacement, critical bolt axial load, and the beam axial load curves were discussed. Finally, using the Least Square Method (LSM), a formula is presented to determine the displacement at the maximum capacity of these connections. This formula can be used in this study's presented method to determine the maximum load capacity of the 8ES connections in a column loss scenario.
