Double skin composite walls are composed of two steel plate “skins” connected by tie bars, with the space between them filled concrete. They were developed to reduce wall thickness, enhance constructability, and enable rapid construction eliminating use formwork reinforcing bars. In present study, cyclic testing was performed investigate seismic behavior isolated coupled double rectangular T-shaped cross sections. The specimens failed mainly tensile fracture welded joints at base coupling...
Flexural tests on full-scale I-shaped beams, built up from high-strength steels (HSB800 and HSA800) with a nominal tensile strength of 800 MPa, were carried out to study the effect flange slenderness flexural rotation capacity. The primary objective was investigate appropriateness extrapolating current stability criteria (originally developed for ordinary steel) steel. For comparison purposes, specimens steel (SM490) also tested showed sufficient capacity in accordance AISC specification....
This paper presents test results on eight reduced beam section (RBS) steel moment connections. The testing program addressed web connection type (bolted versus welded) and panel zone (PZ) strength as the key variables. Specimens with medium PZ were designed to promote energy dissipation from both RBS regions such that expensive doubler plates not needed. Both strong specimens a welded able provide satisfactory rotation capacity for special moment-resisting frames. However, bolted performed...
In this study, the behavior of high-strength steel circular hollow section (CHS) X-joints was systematically investigated by experimental and test-validated numerical analysis. A total nine CHS fabricated from cold-formed tubes were tested under axial compression. The key test variables included different grades steels geometrical configuration joint. joint strength observed mostly governed widely accepted 3% indentation criteria before reaching peak strength. All in study exceeded nominal...
In this study, a parallel axial-flexural hinge model capable of representing postyield flexural behavior and considering interaction effects axial force moment is proposed for simplified nonlinear progressive collapse analysis welded steel frames. To end, the load-resisting mechanism column-removed double-span beams was investigated based on material geometric parametric finite-element analysis. A multilinear point which captures moment-axial tension then proposed. The emphasis to develop...

ABSTRACT In this study, seismic demand on nonstructural components (NSCs) was analyzed using a combined structural‐nonstructural 2‐degree‐of‐freedom (2‐DOF) model. This model specifically employed to incorporate coupling effects, which arise from the dynamic interaction between supporting structures and NSCs. The effect of structure‐NSC peak component acceleration ( PCA ) investigated, with focus key properties such as mass ratio, period ductility. analysis results showed that varies...
This paper describes a seismic design procedure for rib-reinforced steel moment connections based on an equivalent strut model. It is shown from the results of finite-element analysis that force transfer mechanism in rib completely different predicted by classical beam theory and diagonal strip acts as strut. By treating strut, model could be used basis practical proposed first. A step-by-step then recommended
Suspended ceiling systems are among the most frequently reported earthquake-vulnerable nonstructural elements. Despite their importance, a rational seismic design procedure for suspended has not been developed because of complex details and behavior. In this study, performance direct- indirect-hung ceilings was evaluated based on shake table tests. particular, large-size specimen, comparable to an actual constructed size, tested using array two tables highly stiff test frame with overall...
