Abstract:
Multi-layered laminated glass panels are those with at least three monolithic glass layers and two viscoelastic interlayers. Multi-layered laminated glass panels are commonly used in floors, roofs and other horizontal glazing accessible to the public where a high level of security is required. Although the glass can be consider as a linear-elastic material, the viscoelastic interlayers determine a non-linear behavior of the laminated structure that must be taken into consideration. In this paper, a dynamic effective thickness is proposed to predict the natural frequencies and damping ratios of multi-layered laminated glass beam-like structures with different boundary conditions and at different temperatures. Furthermore, the presented dynamic effective thickness can be also used to any frequency domain calculations such as displacements and stresses. To validate the proposed model, operational modal analysis was carried out on a multi-layered laminated glass beam to obtain the experimental natural frequencies and damping ratios at 20, 25, 30 and 35℃. Moreover, a finite element model of the beam was also assembly for the sake of comparison. The proposed model predicts the natural frequencies with errors less than 5%, whereas the discrepancies in damping ratios are less than 50%.

Abstract:
Abstract Glass is a very attractive material for contemporary architecture. The trend is to achieve a maximum transparency of structures; therefore it becomes common to use glass as a material for load-bearing structural elements. Glass facades, roofs, beams or columns are widely used in buildings. The problematic part of a glass structure design is the connection between the glass pieces or between the glass elements and substructures from another material (e.g. steel, concrete etc.). The connection must be capable of bearing the stresses performing during the lifetime period and it should be as unobtrusive as possible at the same time. The ongoing research at the Faculty of Civil Engineering of the Czech Technical University in Prague is focused on an embedded laminated point connection for glass structures. Within this research, the real-scale glass panels were tested. The samples consisted of two glass plies bonded with the EVA foil. For the undrilled ply, the float glass was used in all cases. The thermally toughened or the heat strengthened glass was used for the pre-drilled ply. There was one embedded steel countersunk bolt with HDPE liners placed in each corner of the sample. During the experiment, the samples were horizontally placed using the embedded bolts. The load-bearing capacity of the six tested specimens was determined. The load was applied in several loading and unloading cycles until the collapse of the first embedded connection. If the glass panel failed before the connection, the sample was completely unloaded and then the load was gradually increasing until the collapse of the connection. Vertical deflection and the stresses at two different points were measured during the loading cycles. The humidity and the temperature were also monitored. The experiment showed the way of collapse and a short-term load-bearing capacity of a laminated glass panel with four embedded point connections.

Abstract:
The influence of elevated temperatures on stiffness and strength of composite face sheet and polyethylene terephthalate foam cored sandwich beam has been experimentally investigated. Standard test methods and analytical failure models were used to determine the effect of elevated temperatures. The authors examined E-glass/epoxy cross-ply face laminates, polyethylene terephthalate foam, and sandwich beams consisting of glass/epoxy face laminates and polyethylene terephthalate foam core loaded in four-point flexure. The tensile properties of the face laminate were examined over a temperature range from 25 to 175°C. Compression and shear tests on the face laminate, polyethylene terephthalate foam, and sandwich beams were performed at temperatures up to 100°C. The face laminates exhibited moderate reductions of Young’s modulus and tensile strength, while the compressive strength, shear modulus, and shear strength substantially decreased at elevated temperatures. Similarly, the compressive and shear moduli as well as the compressive strength of the polyethylene terephthalate foam decreased substantially by exposure to a temperature of 100°C. The failure mode of the sandwich panels was observed to be highly dependent on temperature, distinguishing three basic failure modes, viz. core shear failure, indentation failure, and face wrinkling. The failure loads associated to these failure modes were calculated using models available in the literature. The failure loads were found to be consistent with the failure predictions and failure modes.

Abstract:
Abstract Laminated glass panels are increasingly used to improve the blast resilience of glazed facades, as part of efforts to mitigate the threat posed to buildings and their occupants by terrorist attacks. The blast response of these ductile panels is still only partially understood, with an evident knowledge gap between fundamental behaviour at the material level and observations from full-scale blast tests. To enhance our understanding, and help bridge this gap, this paper adopts a ‘first principles’ approach to investigate the effects of high strain-rate, associated with blast loading, and the in-plane restraint offered by blast-resistant frames. These are studied by developing simplified analytical beam models, for all stages of deformation, that account for the enhanced properties of both the glass and the interlayer at high strain-rates. The increased shear modulus of the interlayer results in a composite bending response of the un-fractured laminated glass. This also enhances the residual post-fracture bending moment capacity, arising from the combined action of the glass fragments in compression and the interlayer in tension, which is considered negligible under low strain-rates. The post-fracture resistance is significantly improved by the introduction of in-plane restraint, due to the membrane action associated with panel stretching under large deflections. This is demonstrated by developing a yield condition that accounts for the relative contributions of bending and membrane action, and applying the upper bound theorem of plasticity, assuming a tearing failure of the interlayer. Future work aims to complete the theoretical framework by including the assessment of plate-action and inertia effects.

Abstract:
This paper presents experimental, analytical and numerical investigations about the flexural behavior of glass fiber reinforced polymer (GFRP) pultruded panels for footbridge decks. The analyzed panels, made of isophthalic polyester and E-glass fibers, comprise a multicellular thin-walled cross-section with panel-to-panel vertical snap-fit connections at their lateral edges. As part of a comprehensive study about the mechanical and structural behavior of this type of footbridge decks, the experimental study presented here addresses: (i) the mechanical characterization of the laminated material, and (ii) the quasi-static flexural behavior of the panels for both service and failure conditions. The experimental data obtained is used to validate and assess the accuracy of three-dimensional shell finite element (FE) models and analytical formulae. Particular focus is given to the serviceability and failure performance of the panels, in terms of their deformability and susceptibility to buckling phenomena, respectively. Regarding the serviceability behavior, the results obtained in this study demonstrate the importance of duly specifying the shear coefficient of the multicellular cross-section on Timoshenko beam theory, in order to obtain accurate deflection predictions. In terms of failure performance, both the flexural tests and the analytical formulae indicate that the local buckling of the compressive flanges seems to have triggered the collapse of the tested panels, thus limiting their load carrying capacity. The geometrically nonlinear FE analyses allowed understanding in further depth the ultimate behavior of the panels, providing further insights about their failure mechanisms.

Abstract:
Structural glass beams and fins are largely used in buildings, in the form of primary load-bearing members and bracing systems for roof or facade panels. Several loading and boundary conditions can be efficiently solved by means of bonded composites that involve the use of laminated glass sections. Additionally, the so-obtained glass members are often characterized by high slenderness. To this aim, several literature studies were dedicated to the lateral–torsional buckling (LTB) behavior of laterally unrestrained (LU) glass elements, with the support of full-scale experiments, analytical models, or finite element (FE) numerical investigations. Standardized design recommendations for LU glass members in LTB are available for designers. However, several design issues still require “ad hoc” (and often expensive) calculation studies. In most of the cases, for example, the mechanical interaction between the structural components to verify involves various typologies of joints, including continuous sealant connections, mechanical point fixings, or hybrid solutions. As a result, an accurate estimation of the theoretical LTB critical moment for such a kind of laterally restrained (LR) element represents a first key issue toward the definition and calibration of generalized design recommendations. Careful consideration should be spent for the description of the intrinsic features of materials in use, as well as for a combination of geometrical and mechanical aspects (i.e., geometry, number, position of restraints, etc.). In this paper, the attention is focused on the calculation of the elastic critical buckling moment of LR glass beams in LTB. Existing analytical approaches of the literature (mostly developed for steel constructional members) are briefly recalled. An additional advantage for extended parametric calculations is then taken from finite element (FE) numerical analyses, which are performed via the LTBeam or the ABAQUS software codes. The actual role and the effect of discrete mechanical restraints are, thus, explored for selected configurations of practical interest. Finally, the reliability of simplified calculation approaches is assessed.

AbstractA high specific stiffness, high specific strength, and tailoring the properties for specific application have attracted the attention of the researchers to work in the field of laminated composites and Sandwich structures. Rapid use of these laminated composites and Sandwich structures necessitated the development of new theories that suitable for the bending, buckling and vibration analysis. Many articles were published on free vibration of beams, plates, shells laminated composites and sandwich structures. In this article, a review on free vibration analysis of shear deformable isotropic beams, plates, shells, laminated composites and sandwich structures based on various theories and the exact solution is presented. In addition to this, the literature on finite element modeling of beams, plates, shells laminated composites and sandwich structures based on classical and refined theories is also reviewed. The present article is an attempt to review the available literature, made in the past few decades on free flexural vibration response of Fiber Metal laminated Composites and Sandwich panels using different analytical models, numerical techniques, and experimental methods.

Abstract:
This paper presents a new product, a glass laminate aluminium-reinforced epoxy (GLARE)-based thin-walled structure with a stiffener in the form of a longitudinal rib. The stiffening rib in an outer metallic layer of a GLARE-based panel was fabricated by the incremental sheet forming technique and Alclad 2024-T3 aluminium alloy sheets were used as adherends. The strength properties of the adhesive joint between the layers of the fibre metal laminates (FMLs) were determined in a uniaxial tensile test, peel drum test, tensile/shear test and short-beam three-point-bending test. Two variants of FMLs were considered, with an adhesive film and without an adhesive film between the adherends and the epoxy/glass prepreg. The FMLs were tested at three different temperatures that corresponded to those found under real aircraft operating conditions, i.e., −60 °C, room temperature and +80 °C. It was found that the temperatures do not affect the tensile strength and shear strength of the FMLs tested. However, there was a noticeable increase in the stiffness of samples stretched at reduced temperature. An additional adhesive film layer between the adherends and the glass/epoxy prepreg significantly improves the static peeling strength of the joint both at reduced and at elevated temperatures. A clear increase in the critical force at which buckling occurs has been clearly demonstrated in the uniaxial compression test of GLARE-based rib-stiffened panels. In the case of GLARE-based rib-stiffened panels, the critical force averaged 15,370 N, while for the non-embossed variant, it was 11,430 N, which translates into a 34.5% increase in critical force.

During last decade increased usage of laminated composite glass structures, also annealed and tempered glass can be observed in civil engineering, automobile and space structures, solar panels, etc. Latter trend is caused by high strength properties of laminated glass, also sound and vibration attenuation capabilities. However, heat treatment of glass causes residual stresses, which are not often covered in structural analysis. Current study is focused on experimental evaluation and numerical modelling of residual stresses in glass panels.

Finite-element modeling methods are presented using an existing finiteelement program to (1) predict the stiffness increase, due to the addition of deck panels, for red maple glued-laminated (glulam) T-beam assemblies relative to beams with no deck panels; and (2) predict the midspan beam deflection for a red maple glulam longitudinal stringer–transverse deck bridge for two loading conditions (one lane loaded and two lanes loaded). The red maple T-beam stiffness increase was determined for T-beams assembled with and without gaps between deck panels. The T-beam stiffness increase was predicted to within 5 percent for T-beams assembled with gaps between deck panels and to within 3 percent for T-beams assembled with no gaps between deck panels. Red maple glulam longitudinal stringer–transverse deck bridge maximum midspan beam deflections were predicted to within 6 percent for one-lane loading and to within 7 percent for two-lane loading.

2010/2011
Recentemente, la richiesta architettonica sempre più spinta di trasparenza e luminosità ha favorito la diffusione nell’edilizia del vetro come materiale da costruzione. Sebbene si tratti di un materiale ancora poco conosciuto rispetto ad altri materiali convenzionali, il vetro trova, infatti, ampia applicazione nelle realizzazioni strutturali più innovative. Anche se le soluzioni architettoniche proposte trovano ampio consenso, spesso la difficoltà principale consiste nel dimensionare adeguatamente tali elementi e nel preservarne l’integrità da eventuali fenomeni di instabilità. Con riferimento a questo tema, nella presente tesi vengono proposte alcune significative formulazioni analitiche per la verifica di stabilità di elementi in vetro monolitico, stratificato o vetro-camera, con particolare attenzione per il comportamento di travi compresse, travi inflesse, pannelli sottoposti a compressione nel piano o taglio nel piano. Allo stesso tempo, viene studiato il comportamento di facciate in vetro-acciaio sottoposte a carico da esplosione, con riferimento specifico a due tipologie di facciata note come facciate continue a lastre indipendenti, controventate da un sistema di cavi pretesi, e facciate a pannelli, nelle quali le lastre di vetro sono sostenute da un telaio metallico di supporto. Per ciascuna tipologia di facciata, vengono evidenziate le criticità dovute a carichi da esplosione di varia intensità mediante opportuni modelli numerici. Inoltre, viene analizzato l’effetto di eventuali dispositivi in grado di mitigarne le componenti principali assorbendo e/o dissipando parte dell’energia d’ingresso associata all’evento esplosivo.
Recently, due to aesthetic and architectural requirements of transparency and lightness, the use of glass as a structural material showed a strong increase. Although its load carrying behavior is actually not well-known, glass finds large application in modern and innovative buildings. Nevertheless, the main difficulties are related to the proper design of these structural elements and in the preservation of their integrity, avoiding possible buckling phenomena. In this context, this Doctoral Thesis proposes a series of interesting analytical formulations suitable for the buckling verification of monolithic, laminated, insulated structural glass element, with particular attention for the load carrying behavior of beams in compression or in bending, as well as for the buckling response of glass panels subjected to in-plane compression or shear. At the same time, the Thesis focuses also on the dynamic behavior of two different typologies of steel-glass façades subjected to air blast loads, whit particular attention to the analysis of cable-supported façades and conventional curtain walls, in which a metallic frame supports the glass panels. In both the circumstances, accurate numerical simulations are performed to highlight the criticalities of similar structural systems, in presence of high-level or medium / low-level air blast loads. Finally, the structural benefits of possible devices able to mitigate the effects of explosions in the main components of these façades, by partly storing / dissipating the incoming energy, are investigated numerically and analytically.

ASik May 2010, 33 Pages In this thesis, experimental studies are carried out on curved laminated glass beams to form a database for the scientists who may like to test their mathematical models. Beams which are only free to rotate and constrained in radial direction at both ends are tested to make the data available for further calculations. Test setup is prepared to minimize error that could occur due to test setup and data readings. Material testing machine and 4 channel data collecting machine are used to measure the signals at the strain gauges located over the glass beam. Within the range of force applied to the specimens, laminated curved beam shows linear behavior without any fracture. Data collected from the specimens are in conformance with each other. Results obtained from experiments are compared with the results obtained from the mathematical model developed by ASik and Dural (2006). As it is observed from the graphs presented, experimental results from the tests and numerical results from the mathematical model are in good agreement.

Dissertação de Mestrado Integrado em Engenharia Civil apresentada à Faculdade de Ciências e Tecnologia
Over the last few decades, there has been a considerable expansion in the use of glass in several sectors of the industry. Its excellent aesthetic properties and potential to improve the energy performance of buildings make this material extremely appealing for both modern architecture and engineering structures. The growing interest in glass as a structural material potentiated the development of numerous applications and has allowed the emerging of modern structures with an increased level of transparency.However, and in spite of the considerable evolution that has occurred in the glass industry, the behavior of glass laminates as structural elements is still insufficiently studied and the existing regulation is incomplete, leading to the development of uneconomical solutions and hampering the expansion of the utilization of this material.In the investigation regarding the properties and the mechanical response of structural glass, the influence of long-term actions is of particular interest, affecting its behavior significantly and having as main consequence the reduction of the load bearing capacity and resistance of this element overtime. One of the main aspects responsible for the deterioration of the effective properties of glass is an environmental phenomenon designated as Stress Corrosion. In addition to that, the materials applied as lamination films are characterized by having properties that depend on mechanical and environmental factors and by deforming over time due to phenomena of creep and relaxation, which results in a contribution to the diminishment of the resistance of laminated glass and ultimately leads to the occurrence of delamination.The present dissertation aims to deepen the study of this theme, reducing the level of uncertainty regarding the expectable long-term behavior of laminated glass beams, both in intact and fractured conditions, through the development of full-scale long-term experimental tests, in which the considered structural layout and loading strategy resemble a real structure situation.The elaborated work lies within the framework of the “S-GLASS: Desempenho Estrutural e Regras de Projeto de Vigas de Vidro Reforçadas Externamente” is being developed at the University of Coimbra.
Ao longo das últimas décadas tem-se verificado uma expansão considerável na utilização do vidro em vários setores da industria. As suas excelentes propriedades estéticas e o seu potencial para melhorar o comportamento energético dos edifícios, tornam este material extremamente apelativo para a arquitetura e para a engenharia modernas. O crescente interesse no vidro como material estrutural potenciou o desenvolvimento de numerosas aplicações, e permitiu o aparecimento de estruturas modernas com um nível de transparência cada vez maior.No entanto, e apesar da considerável evolução que se tem verificado na industria vidreira, o comportamento dos laminados de vidro como elementos estruturais está ainda pouco estudado e a atual regulamentação torna-se incompleta, conduzindo à obtenção de soluções pouco económicas e dificultando a expansão da sua utilização.No âmbito da investigação das propriedades e da resposta mecânica dos elementos de vidro laminado, a influência das ações de longa duração torna-se de particular interesse, afetando significativamente o seu comportamento e tendo como principal consequência a redução da capacidade de carga e resistência destes elementos ao longo do tempo. Um dos principais responsáveis por esta deterioração das propriedades efetivas do vidro é um fenómeno ambiental designado como “Stress Corrosion”. Adicionalmente, os materiais utilizados como película de laminação caracterizam-se por possuir propriedades dependentes de fatores mecânicos e ambientais e por se deformarem ao longo do tempo devido a fenómenos de fluência e relaxação, contribuindo também para diminuição da resistência do vidro laminado. A presente dissertação pretende aprofundar o estudo desta problemática, reduzindo o grau de incerteza relativamente ao comportamento expectável a longo prazo de vigas de vidro laminado, tanto intactas como fraturadas, através do desenvolvimento de ensaios de longa duração à escala real, tendo-se adotado um esquema estrutural e de carregamento semelhantes a uma situação frequente em estruturas reais.O trabalho elaborado encontra-se no âmbito do projeto “S-GLASS: Desempenho Estrutural e Regras de Projeto de Vigas de Vidro Reforçadas Externamente”, desenvolvido na Universidade de Coimbra.

Abstract:
Various examples of glass load bearing structures such as beams, columns, panes, or even stairs are used in a current architecture. For safety reasons, these members are mostly made of laminated glass. Polymeric interlayers are used for glass plates bonding and their shear stiffness, as a time-temperature dependent parameter, meaningly influences the response of the entire perpendicularly loaded laminated glass pane. Even though the shear stiffness of the interlayer is available, the exact stress-state analysis of the pane is rather challenging. This paper compares the results of perpendicularly loaded double laminated glass panes at various boundary conditions, calculated by current advanced analytical methods and by the draft of the European standard prEN 16612 to the numerical simulation performed in RFEM 5®. Important differences between these methods are illustrated. Futher recommendations for a design of these structures in practice are also provided.

Abstract:
<p>Trends in modern architecture are heading towards a complete transparency of structures, which makes glass a very popular building material. However, achieving a completely transparent look of a structure may be problematic mainly due to glass elements connections. The connections must be capable of bearing all stresses performing during the lifetime period and meet high aesthetical standards at the same time. An embedded laminated point connection represents a progressive glass fixing systems. An ongoing research of the Czech Technical University in Prague is focused on the characteristics of this type of connection. Within this research, a set of real-scale laminated banister panels with two sets of embedded point connections was tested. The experiment showed the way of collapse and a short-term resistance of a laminated glass panel with two sets of embedded point connections under vertical loads.</p>

Abstract:
This paper describes a study that was undertaken to simulate impacts on laminated float glass/polycarbonate/float glass panels using the Johnson-Holmquist (JH-2) model for brittle materials and the EPIC explicit finite element code. The simulation results are compared with observed impact results obtained by others. The JH-2 model was originally successfully calibrated to treat impact on thick monolithic glass slabs. In this study recent spall strength data for glass reported in the literature was used to revise the JH-2 model for application to thin laminated glass panels — a system of wide technical interest. The JH-2 coefficients developed were further validated by comparison with an additional independent data set obtained from the literature involving glass rod impact data. A good fit to both data sets considered was produced suggesting that the revised JH-2 coefficients proposed are reasonable.

Abstract:
<p>Finansparken Bjergsted is an office building currently under construction in Stavanger, Norway, for SR-Bank. The structural system above ground level uses timber as the principal load bearing elements (a natural, renewable and readily available local material). Floors are cross-laminated timber (CLT) panels supported by glued laminated timber (GL) beams and columns. For strength and complex geometrical requirements, laminated veneer lumber (LVL) made of beech is also used. The three basement levels and the four communications and services cores are of reinforced concrete. Mass timber structural elements are engineered for strength and are prefabricated with strict tolerances for a rapid construction process using mainly direct contact timber connections, without metal fasteners. The beams are shaped and fabricated with openings to suit both the architectural aesthetics and services requirements by means of a fully integrated BIM system.</p>

Abstract:
Abstract The Affordable Composite for Propulsion (ACP) program is investigating material designs and manufacturing processes which produce affordable and structurally acceptable parts for turbofan engine applications. In order to evaluate material architectures for engine structures susceptible to bird impact events, soft body impact tests were performed on laminated and 3D woven composite flat panels. Material architecture variables such as graphite/glass hybridization, stitching and type of stitch fiber for laminated composites, and ply-to-ply and through thickness interlock weaves for 3D materials were investigated. The primary test results of interest were damage resistance (velocity or energy to initiate measurable damage) and damage tolerance (resistance of the panel to propagation of existing damage). The results of these experiments are presented, and the behavior of the various material architectures are compared and contrasted. Material architecture variables which increase the soft body impact damage resistance and tolerance will be noted.
