Abstract (sommario):
In a joint project of a German working group supported by the ECSC and the Studiengesellschaft fu¨r Stahlanwendung e.V., the fatigue behavior of large-scale hybrid tubular joints with inserts manufactured from the high-strength cast steel GS-12 MnMo 7 4 welded into tubular members formed from the fine-grained steel StE 500 were compared to the behavior of large-scale welded tubular joints. The latter were made from medium-strength fine-grained steel StE 355 and high-strength StE 690. In addition, data from hybrid joints with cast steel inserts of medium-strength GS-8 Mn 7 welded into StE 355 tubulars is available for comparison. The tests were carried out under variable amplitude loading in artificial seawater. The results were evaluated for the failure criteria fatigue life to crack initiation (a = 1 mm) and through crack. With medium-strength (Rp0.2 > 355 N/mm2) hybrid tubulars, where by the use of cast steel inserts the welds were removed into areas of lower stress concentration, fatigue lives higher than a factor of 100 were achieved compared to the welded nodes, even those made from StE 690. However, by the use of high-strength (Rp0.2 > 500 N/mm2) cast steel inserts and tubular members of corresponding strength, the fatigue life to crack initiation was improved by a factor of two despite a thickness reduction compared to the medium-strength design. Post-weld treatments of the welded tubulars without cast steel inserts like shot-peening, TIG-dressing, or their combination resulted only in a slight increase of fatigue life. The results of this investigation do not only show how to improve the fatigue life by a new design using cast steel inserts, but indicate also how to revise design codes from the point of damage calculation (damage sum of 0.50 for welded nodes and 0.25 for cast steel inserts instead of the conventional value of 1.00), as well as consideration of fatigue life to initiation of a technically detectable crack with a defined depth e.g., a = 1 mm.

Abstract (sommario):
Using ObjectARX, an integrated CAD/CAM software for steel tubular truss structures has been developed based on AutoCAD platform and Visual studio.Net environment. The design ideas and the application effects are introduced in this paper. Because of different data requirements in different design stages of steel tubular structures, i.e., the whole structure design and the detail design, a wireframe model and a solid model were adopted in the software, respectively. Joint lofting is the key point in manufacturing of complex tubular trusses. To solve this, 3D solid model was constructed by self-defined solid objects, which were designed with inheritance of class AcDb3dSolid in ObjectARX, and Boolean operation was used to realize 3D end lofting of branch pipes. Based on the lofted solid model, the G-codes can be generated automatically. At last, an actual tubular truss structure was designed and lofted by using the software. The proposed software package realizes the integration of CAD/CAM and it can greatly reduce the cost and time of design and fabrication, improve the quality of construction.

Abstract (sommario):
Purpose The purpose of this paper is to investigate the static and dynamic inelastic response of rigid and semi-rigid connections of steel structures with concrete-filled steel tube (CFST) columns built in high seismic areas, and to compare it with those with open section columns. Design/methodology/approach CFST columns are frequently used in moment resistant steel frames located in seismic areas due to their inherent advantages, including their ductility, energy absorption capacity as well as their high bearing capacity. The smart combination of steel and concrete makes it possible to benefit from the advantages of both components to the maximum. This research work presents the nonlinear dynamic response of moment resistant steel frames with CFST columns, with rigid or semi-rigid connections, built in high seismic areas, according to the Algerian seismic code RPA 99/2003, European EC8 and American FEMA 356 to show the nonlinear characteristics of this type of structures, and their advantages over steel frames with open section columns. Findings The paper presents the advantages of using CFST columns with rigid and semi-rigid connections on the seismic response of portal steel frames. A high performance level in terms of ductility, plastic hinges distribution and their order of appearance has been obtained. It also shows the low effect of seismic loading on the structural elements with CFST columns compared to structures with open section columns. Originality/value The investigation of the numerical results has shown the possibility of their use in the seismic areas for their adequate performance, and also with respect to the design limits specified in the seismic guidelines. In addition, this study represents a first step to develop seismic performance factors for steel structures with CFST columns in Algeria, where the Algerian code do not include a comprehensive specification for the composite steel structures.

Abstract (sommario):
Cast steel nodes are being increasingly popular in steel structure joint application as their advanced mechanical performances and flexible forms. This kind of joints improves the structural antifatigue capability observably and is expected to be widely used in the structures with fatigue loadings. Cast steel node joint consists of two parts: casting itself and the welds between the node and the steel member. The fatigue resistances of these two parts are very different; the experiment results showed very clearly that the fatigue behavior was governed by the welds in all tested configurations. This paper focuses on the balance fatigue design of these two parts in a cast steel node joint using fracture mechanics and FEM. The defects in castings are simulated by cracks conservatively. The final crack size is decided by the minimum of 90% of the wall thickness and the value deduced by fracture toughness. The allowable initial crack size could be obtained through the integral of Paris equation when the crack propagation life is considered equal to the weld fatigue life; therefore, the two parts in a cast steel node joint will have a balance fatigue life.

Abstract (sommario):
As the most basic structure, the concrete-filled steel tubular (CFST) frame has been widely used in various structures and systems. Compared with conventional reinforced concrete structures and steel structures, CFST structures in strong earthquake showcase more complicated strength and deformation behavior because there are many factors underlying the failure mode. Furthermore, according to the specifications at home and abroad, the corresponding design method to achieve reasonable failure modes for CFST structures has not been clarified. Based on a destructive test on steel beam-CFST plane frames under constant axial load and lateral load, the fiber mode method and solid element model method are adopted to simulate the failure process of the test frames. Based on finite element model simulations and tests, the fiber model method is proposed to carry out the pushover analysis on the CFST frame structures. The factors behind the reasonable failure mode of steel beam-concrete-filled circular steel tubular (CFCST) frame structures are analyzed. Furthermore, the law and influencing factors behind the ratio of flexural capacity of column to beam, the ratio of line stiffness of beam to column, and the ratio of axial compression on the deformation, bearing capacity, and failure modes of the structure are discussed. Some suggestions on the design of reasonable failure mode of steel beam-concrete-filled circular steel tubular (CFCST) frame structures are proposed.

Abstract (sommario):
Offshore towers standing in deep sea are susceptible to cyclic nature of wave forces. Fatigue failure initiates at the welded tubular joints of these structures where a very high stress gradient and localized stress concentration exist due to abrupt changes in the geometry. Stress concentration plays a vital role in the design of steel tubular joints, as it directly affects the fatigue life of the structures. This paper presents results of an experimental study on the behavior of an unstiffened and a stiffened steel tubular welded T-joint under axial brace loading. The effect of internal ring stiffeners has been studied theoretically and experimentally. In the experimental technique, the specimens were extensively strain-gaged and the stress distribution determined under static load. The analytical results have been obtained by finite element technique.

Resumo: Este trabalho tem como objetivo apresentar análises comparativas entre estruturas metálicas treliçadas tubulares planas considerando as vinculações entre as barras como rotuladas e estruturas metálicas treliçadas tubulares planas considerando as vinculações entre as barras como rígidas. A motivação deste estudo foi determinar qual a importância da rigidez das barras no dimensionamento das mesmas estruturas quando são consideradas diferentes vinculações entre as barras. Foram encontradas diferenças nos dimensionamentos quando as barras são ¿curtas¿ e conseqüentemente, bastante rígidas. Nestes casos, onde as barras são rígidas, a consideração de rótula leva a resultados que não condizem com o comportamento real da estrutura e, conseqüentemente, a um dimensionamento inadequado da estrutura tubular. Para agilizar as análises, foi desenvolvido um software que automatiza as etapas principais de um projeto de estruturas metálicas tubulares planas, com o objetivo de enquadrar tais análises em condições que respeitem os parâmetros normativos de ângulos entre barras, limites de esbeltez, entre outros. As etapas automatizadas foram: geração automática de determinadas geometrias, cálculo dos coeficientes de pressão e forma do vento e pressão dinâmica, carregamento automático da estrutura, cálculo estrutural e dimensionamento da estrutura. O programa possui uma interface amigável, integrada e ágil que permite aos projetistas de estruturas metálicas realizarem diversas análises possibilitando de forma rápida a escolha da solução mais adequada para a estrutura
Abstract: This research has the objective to present a comparative analysis between steel plane tubular trusses that consider the member¿s end connections as released and steel tubular plane trusses that consider the member¿s end connections as non-released (rigid). This study intends to measure the member¿s stiffness importance for the design of these members when them are considered released or not. It was found differences when the members were ¿short¿ and very rigid. In this cases, when the members were rigid, the released consideration takes to results that don¿t represent the real behavior of the structure and, consequently, to an inadequate design of the tubular structure. To make the analysis faster, it was developed a software that automate the major steps of a steel tubular structure design, with the objective to fit the analysis in the standard design recommendations, like angles between members, stiffness limits, and others. The automated steps were: automatic generation of geometries, automatic wind pressure calculation, automatic structure load insertion, structural analysis and steel structure design based on Brazilian codes. The software has a friendly interface, which allows engineers realize several analyses and, thus, choose the most adequate solution for the structure

Abstract (sommario):
Concrete filled steel tubular (CFST) columns are widely used in building and infrastructure projects throughout the world.Compared with other form of construction CFST columns offer superior structural performance and speed and ease of construction.Design procedures and recommendations provided in most of the design codes are often tedious and complex. There have been attempts to simplify the design procedure by providing a simplified expression to predict the capacity of a CFST under a general loading condition.In this thesis a rigorous analysis procedure was presented for the analysis of CFST beam-columns under general loading conditions.All the analytical results were verified by comparisons with the available test results and current ACI, AISC AND Eurocode 4 design codes. The comparisons demonstrated that the proposed numerical equations are accurate, and slightly conservative. Based on the numerical analysis, a simple and easy to follow calculation procedure was proposed for design of CFST columns under either uniaxial or biaxial bending moment and axial load.

Abstract (sommario):
Ce sujet est d’actualité suite à une évolution rapide des types de conception de structures élancées utilisées dans les installations provisoires. C’est seulement depuis une vingtaine d’années que ces structures sont préfabriquées en cadres multidirectionnels (de sections tubulaires en acier ou en aluminium). Ces structures sont légères et leur stabilité réside seulement dans les raideurs internes au niveau des files de montants et au niveau horizontal par les planchers ainsi que dans les liaisons avec l’ouvrage. Ce travail concerne l’étude des instabilités (flambement-déversement) en tenant compte de différents types d’imperfections. De nouvelles courbes de flambement ainsi que les facteurs d’imperfection associés sont proposés dans cette thèse. Ces courbes sont obtenues en imposant une déformée initiale représentant les défauts géométriques et mécaniques (contraintes résiduelles). Les résultats expérimentaux confrontés avec les prévisions théoriques de l’Eurocode 3 montrent que les valeurs des imperfections figurant dans la littérature sont extrêmement exagérées. Les valeurs préconisées dans ce travail pourraient présenter un certain intérêt pour une modification éventuelle des courbes européennes de flambement pour ce type de structure. En ce qui concerne l’instabilité latérale, une méthodologie originale d’essais en vraie grandeur de poutres à treillis formés d’éléments tubulaires a été également mise au point. Le système de chargement à « roues libres » développé permet de libérer le point d’application de l’effort dès le début de l’instabilité. Cette technique conduit à des mesures plus précises du moment critique de déversement
This subject becomes topical following a rapid evolution of design procedures for slender structures used widely in the temporary installations. Only through the last twenty years that these structures are prefabricated of multidirectional frames (steel or aluminium tubular sections). These structures are lightweight and their stability lies only in the internal stiffness at rows of posts and horizontally by the planking as well as the links with the building. This work concerns the study of instabilities (buckling - lateral torsional buckling) taking into account different types of imperfections. New buckling curves and the associated imperfection factors are proposed in this thesis. These curves are obtained by imposing an initial deformed representing the geometrical and mechanical defects (residual stress). The experimental results were confronted with theoretical predictions of Eurocode 3 which show that the values of the imperfections in the literature are extremely exaggerated. The values advocated in this work could be of interest for a possible adjustment of the European buckling curves for this type of structure. Regarding the lateral instability, an original methodology in real scale tests of trusses consist of tubular elements was also developed. The developed loading system of "free wheels" allows releasing the point of application of the force from the beginning of instability. This technique leads to more accurate measurements of the critical lateral torsional buckling moment

FINITE ELEMENT MODELING OF CONCRETE-FILLED STAINLESS-CLAD BIMETALLIC STEEL SQUARE TUBES UNDER AXIAL COMPRESSION. The Hong Kong Institute of Steel Construction, agosto 2022. http://dx.doi.org/10.18057/icass2020.p.276.

Testo completo
Abstract (sommario):
As an advanced high-performance bimetallic steel, metallurgically bonded stainless-clad (SC) bimetallic steel has been increasingly used in engineering structures in recent years. Its combination use with concrete in composite structures is beneficial to not only the corrosion resistance and economy, but also to the loading capacity. However, at present, the numerical analysis model suitable for the SC bimetallic steel is still in the lack stage. In order to study the deformation and mechanical properties of concrete-filled stainless-clad bimetallic steel square tubular (CFBSST) stub columns under axial compression, two finite element (FE) models are established based on the FE software ABAQUS. The simulation results are compared and validated according to the experimental results. Finally, the advantages, disadvantages and application scope of each model are summarized to provide reference for subsequent research.

NUMERICAL INVESTIGATION ON CYCLIC BEHAVIOR OF RING-BEAM CONNECTION TO GANGUE CONCRETE FILLED STEEL TUBULAR COLUMNS. The Hong Kong Institute of Steel Construction, dicembre 2021. http://dx.doi.org/10.18057/ijasc.2021.17.4.7.

Abstract (sommario):
As a promising composite structure, gangue concrete filled steel tubular (GCFST) column exhibites favarable characteristics including high strength and economic efficiency. This paper conducted numerical investiagations on structural behavior of a ring-beam connection to GCFST column with concrete beam under cyclic loading. Furthermore, finite element models of column-beam connections were developed using ABAQUS and validated against full-scale experimental tests to identify accuracy of selected modeling approaches. Using these validated models, stress distribution of each component was examined to study the force-transferring mechanism among the components and failure modes of the ring-beam connection. Research study indicated that the ring-beam connection showed a reasonable force-transferring mechanism under cyclic loading and the remarkable earthquake-resistant performance with high capacity and acceptable ductility. Finally, parametric studies were performed to assess the influences of beam-to-column stiffness ratio,steel ratio, axial load level, and concrete compressive strength on connection cyclic behaviors. Parametric studies provided some suggestions and references for the application of the ring-beam connection in various engineering projects.

OVERHANG EFFECT ON WEB CRIPPLING CAPACITY OF COLDFORMED AUSTENITIC STAINLESS STEEL SHS MEMBERS: AN EXPERIMENTAL STUDY. The Hong Kong Institute of Steel Construction, agosto 2022. http://dx.doi.org/10.18057/icass2020.p.343.

Testo completo
Abstract (sommario):
This paper studies the overhang effects on ultimate bearing capacities of cold-formed austenitic stainless steel square hollow section (SHS) members undergoing web crippling between EndTwo-Flange (ETF) and Interior-Two-Flange (ITF) loading conditions. A total of 16 web crippling tests were conducted with specimens covering various overhang lengths. Tensile coupon tests were performed to obtain the material properties of the test specimens. The web crippling capacities obtained from the tests were compared with the nominal capacities predicted by the SEI/ASCE 8-22 Specification for the design of cold-formed stainless steel structural members. It is shown that the SEI/ASCE 8-22 Specification leads to overly conservative web crippling capacity predictions for the tubular specimens with overhangs. The applicability of the overhang effect enhancement factor codified in the AISI S100- 16 Specification to the studied stainless steel specimens was evaluated. It is revealed that the accuracy and consistency of the web crippling capacity predictions can be enhanced by employing the enhancement factor codified in the AISI S100-16 Specification, yet such a treatment still leads to rather scatter predictions and can lead to unconservative capacity estimations. An extended investigation is currently underway to propose improved design rules for cold-formed stainless steel tubular members with overhangs under ETF loading condition.

EXPERIMENTAL AND NUMERICAL INVESTIGATION ON SEISMIC PERFORMANCE OF RING-BEAM CONNECTION TO GANGUE CONCRETE FILLED STEEL TUBULAR COLUMNS. The Hong Kong Institute of Steel Construction, marzo 2022. http://dx.doi.org/10.18057/ijasc.2022.18.1.9.

Testo completo
Abstract (sommario):
This paper presents an investigation on seismic performance of a ring-beam connection that is used to connect reinforced gangue concrete (RGC) beam to coal-gangue concrete-filled steel tubular (GCFST) column. Two specimens, including an interior connection with two beams and an exterior connection with one beam, were designed and fabricated for experimental tests under full-reversing cyclic loads at beam ends. In addition, finite element models which corresponded to tested specimens were developed using ABAQUS to conduct numerical simulations of the composite connection subjected to the combined axial and cyclic loads. The feasibility of the developed model to predict failure modes and load-deformation response of the connection was validated by comparing with test results. The response of the ring-beam connection to cyclic loads was examined with respects to the load-bearing capacity, deformation resistance, stiffness and strength degradation, ability to dissipate energy in a seismic event, and ductility. With numerical models, parametric analysis was completed to evaluate the influences of material and structural parameters on connection resistance against cyclic loads. Based on the results of parametric studies, a restoring force model of skeleton curve for the ring-beam connection was developed in terms of ultimate capacity and corresponding deformation. The results provided practical suggestions for the application of ring-beam connection to GCFST column in the projects.
