ELASTIC-PLASTIC ANALYSIS OF STEEL BRACED FRAME SUBJECTED TO REPEATED HORIZONTAL LOAD

Investigation of different methods in strengthening braced steel frame under blast load

Unpredicted loading caused by blast or impact may lead to severe damage in structures. Such damage may affect the whole structural performance. Connections are the key contributor to the integrity and energy dissipation capacity of the structural steel systems and play the most important role in mitigating such consequences. In the view of the importance of connections, finite element analysis ...

analysis of elastic-plastic behavior of fiber metal laminates subjected to in-plane tensile loading

fiber metal laminates are hybrid laminates consisting of thin alternating bonded layers of aluminum and fiber/epoxy. arall (aramid aluminum laminate) and galare (glass fiber reinforced aluminum laminate) are specific kinds of fiber metal laminates that consist of thin aluminum sheets along with kevlar/epoxy and glass/epoxy composite layers, respectively. in this study, nonlinear tensile behavio...

Ultimate Load Capacity and Behavior of Thin-Walled Curved-Steel Square Struts, Subjected to Compressive Load

There have been some experimental tests on hollow curved-steel struts with thin-walled square sections, in order to investigate their general behavior, particularly their capacity for bearing differing loads. One set of square tubes are cold-formed into segments of circular arcs with curvature radii, equal to 4000 mm. Different lengths of curved struts are fabricated so as to cover a practical ...

OPTIMUM PERFORMANCE-BASED DESIGN OF CONCENTRICALLY BRACED STEEL FRAMES SUBJECTED TO NEAR-FAULT GROUND MOTION EXCITATIONS

This paper presents a practical methodology for optimization of concentrically braced steel frames subjected to forward directivity near-fault ground motions, based on the concept of uniform deformation theory. This is performed by gradually shifting inefficient material from strong parts of the structure to the weak areas until a state of uniform deformation is achieved. In this regard, to ove...
