“…Numerous researches on the steel plate shear wall have been conducted where experimental studies on the flat steel plate shear walls (FSPSWs) have been performed under cyclic loading (Caccese et al ., , Driver et al ., , Timler et al ., , Topkaya and Kurban, ). Moreover, analytical studies on the shear buckling characteristics and behavior of the multistory thin steel shear wall have been conducted as well (Roberts, , Timler et al ., , Sabouri‐Ghomi et al ., , Bhowmick et al ., , Berman, ). The shear buckling behavior of the steel plate is the main concerns of the FSPSWs.…”

SUMMARY At present, corrugated plates have numerous applications such as web of plate girders and aerospace applications. Higher out‐of‐plane stiffness and initial elastic strength of the corrugated plates compared with flat plates are reasons for consideration. This study investigates the behavior of trapezoidally corrugated steel plate shear walls (TCSPSWs) under monotonic and cyclic loadings. Finite element analyses that include both material and geometric nonlinearities are employed for the examination. The results from finite element analysis are verified through tested specimen findings. Moreover, the behavior of the steel shear walls with the flat infill panels and the corrugated plate infill panels is compared. The results show that explicit dynamic analysis is the most suitable analysis for the TCSPSWs under quasi‐static loading. Furthermore, although strength of the TCSPSWs obtained from the finite element analysis and the test are fully coincident in elastic region, nonetheless, they are fairly coincident in elastic–plastic and plastic region.

“…For dynamic phenomena, using dynamic constitutive relation is more rational than using static constitutive relation, and the mechanism lies in that the stiffness matrix is relative to strain rate. Bhowmick et al investigated the effect of loading rate on the dynamic behavior of steel plate shear wall by the non-linear dynamic analysis using the ABAQUS software, which revealed that the ductility of structure reduced and the average flexural demand at the base of the wall increased with higher strain rates (Bhowmick et al [21]). In this paper, we studied the effect of strain rate on the collapse mode and collapse-resistant capacity of transmission tower-line system under earthquake.…”

High-voltage electric transmission tower may collapse under the strong earthquake and studies on the collapse mechanism, routine and capacity of transmission tower-line system are important for the structural design of tower. In this paper, a progressive collapse analytical procedure for the system is proposed based on the finite element method (FEM). During this procedure, the mass of the elements is still retained rather than removal after elements lose the load-bearing capacity. The proposed procedure is coded using the user subroutine VUMAT and then implemented in the advanced finite element program ABAQUS. A three-dimensional finite element model for the system of three towers and four-span lines is created. By using the coded subroutine, the collapse analysis of the tower-line system under the strong earthquake is performed. Collapse processes along longitudinal and lateral direction are studied, respectively. Furthermore, the influences of ultimate strain and strain rate effect of materials on the collapse mode and capacity are studied. The results indicate that the collapse analysis of the tower-line system by using the proposed procedure can provide collapse mode and vulnerable points for use in seismic performance and retrofit evaluation of structure. It is found from the numerical modeling that the influences of ground motion and ultimate strain on the collapse modes are apparent. The collapse-resistant capacity of system increases remarkably with the increase of ultimate strain and influences of strain rate on collapse routine and capacity are tiny in analytical results.

“…The basic form of these empirical equations is related to the height of the building, which is T = C t H x or T = C t H , where C t and x are constants depend on the structural type of buildings . Though the empirical equations seem simple, the period results of SPSW structures derived from these equations are conservative in most cases , especially for buildings in low to moderate earthquake regions. Based on the equations in codes, Bhowmick et al corrected the values of C t and x via a regression analysis of various data.…”

Summary Steel plate shear wall (SPSW) has been widely used as a lateral force resisting system (LFRS) for medium or high‐rise buildings. The fundamental period is an important parameter for seismic design and seismic risk assessment of building structures. In this paper, a simplified method is developed for the period prediction of SPSW structures based on the basic theory of engineering mechanics. It estimates a SPSW structure as a shear system of steel frame and a shear‐flexure system of SPSWs separately. The fundamental period of the SPSW structure is calculated according to the integration of the lateral stiffness of the steel frame and SPSWs along the height. A corrected formula is proposed based on the fitting analysis of the ratio of the FEM period to the estimated period. A shaking table test is used to validate the corrected formula, the relative error between the corrected result and the test result is 5.0%. Besides, the proposed method is also compared to some existing methods for the period prediction of SPSW structures, the results indicate that the proposed method has good accuracy and can be hand‐calculated. Finally, a probability‐based method is proposed for the corrected formula, and the fundamental period could be determined with a certain guarantee. A confidence interval estimation could be determined via the proposed method according to the demand of structural design.
