“…Thereby, by applying initial geometrical imperfections, it must be turned into a problem with continuous response rather than bifurcation. Usually, the probable constructional distortion of steel plates is considered as a multiple of the first mode shape of buckling obtained by an elastic buckling analysis (Broujerdian et al, 2015, 2016; Graciano et al, 2011; Reis et al, 2016b). In this article, applying shear load on two sides of the middle stiffeners using ABAQUS shell edge load command, first eigenmode of each girder is obtained by linear buckling analysis.…”

“…Initial imperfection with a shape compatible with the first buckling mode decreases the strength more than other shapes. On the other hand, increasing the imperfection amplitude causes reduction in the ultimate strength (Broujerdian et al, 2016; Chacón et al, 2010a; Garlock and Glassman, 2014; Graciano et al, 2011; Reis et al, 2016a, 2016b) For structural plate elements, in the absence of a high-precision analysis of the geometric imperfection, 80% of the essential manufacturing tolerance for welded profiles (0.8D/100) may be used as the equivalent geometric imperfection at both ambient and elevated temperatures (Chacón et al, 2010a; EN 1993-1-5, 2006; Graciano et al, 2011; Reis et al, 2016a, 2016b), where “D” denotes the web depth of the plate girder. Thereafter, the initial shape of girder in nonlinear static analysis is assumed to be compatible with the first buckling mode of the girder with the amplitude of 0.8D/100.…”

In literature, there is no theoretical research focusing on moment–shear interaction behavior of the hybrid girders. This article investigates the moment–shear interaction behavior of non-composite hybrid steel plate I-girders at ambient and elevated temperatures. In this regard, based on a more realistic distribution of bending and shear stresses, theoretical equations have been proposed to achieve the moment–shear interaction curve without considering shear buckling. The results obtained from the proposed equations were compared with the results of the existing experimental data and those of the finite element analysis. According to the results, there is good agreement between them.

“…Although the crack affects the results of experimental tests, its effect has not been studied comprehensively until now. In other words, despite the impact of the crack on the SPSW performance, there are only two published findings considering the SPSW affected by crack [11,12]. The crack propagation had only been numerically evaluated in these references, and the results had focused on seismic parameters of cracked SPSWs.…”

The Steel Plate Shear Walls (SPSWs) are known as a capable system to use in steel structures due to their significant advantages. Despite extensive studies concerning this system, few researchers have scrutinized thecrack effect on SPSW behavior. However, the crack dramatically affected the experimental results. In the currentpaper, the effect of central and edge cracks, therefore, has been studied in jointed plates at mid-height of SPSW.Results indicated that the central crack is more destructive than the edge crack. The central crack having a long initial length also makes a sudden wall fracture in the elastic zone and consequently cannot be used in high seismic regions. Due to the dependence of the wall on the diagonal tension field and its angle, an equationis proposed taking into account shear, axial, and moment actions in columns, axial and moment actions in beams, as well as shear and axial actions in the plate which conform to finite element results. Because of thecomplication of the stress intensity factor for mode I and mode II calculations, this confidence is derived and offered.

“…In this section, a literature review related to cracked SPSWs is summarized. An investigation on the impact of cracks on the seismic behavior of USPSWs was performed by Broujerdian et al [15]. It was found that crack propagation had a significant effect on the seismic behavior of USPSWs in the elastic and inelastic regions that cannot be overlooked.…”

Currently, the steel plate shear wall (SPSW) is commonly used in high-rise steel buildings as a lateral load-resisting system due to its several advantages such as its lightweight and high ductility and strength. The SPSW consists of two main parts, i.e., the boundary frame and infill plate, which are connected by welding. The objective of this work is to study the effect of the infill plate weld separation on the seismic behavior of the SPSWs. A numerical method was proposed to have a comprehensive comparison of seismic behaviors of different separation characteristics. The model was validated by using previously published experimental works. Key parameters, such as load-carrying capacity, stiffness, and energy-dissipation capacity, were discussed extensively. The unstiffened SPSW (USPSW) system is more sensitive to the plate–beam separation than the plate–column one, especially the corner plate–beam separation. When plate–column welding separation occurs, the initial stiffness and the energy dissipation capacity are reduced by approximately 21% and 14%, respectively; however, the reductions are 36% and 20.5% in the case of beam welding separation.
