“…As can be observed, most of these systems are adopted from the building structures. In building structures, the use of a steel plate shear wall (SPSW) as a primary lateral load resistance system has grown, especially in seismic regions (Berman, 2011;Chen and Jhang, 2011;Bhowmick et al, 2011;Qu et al, 2012;Nie et al, 2013;Alavi and Nateghi, 2013). SPSWs behave in a noticeable ductile manner and dissipate a considerable amount of energy when subjected to cyclic inelastic deformation.…”

Damage suffered by slab-on-girder steel bridges during low-to-moderate seismic excitations reveal the deficiency of standards and codes and indicate the necessity of obtaining insight to the lateral load path and the capacity of individual component and assembled systems. In this paper, to improve the seismic performance of this type of bridges, the lateral load path was initially studied. Subsequently, thin steel infill plates were placed on the seismic load path to dissipate the imposed energy. The results indicate that the use of stocky infill plates with common yielding stress as end diaphragms leads to elastic behaviour of the end diaphragm, at least up to displacement corresponded to the ultimate strength of the substructures, whereas thinner infill plates with low yield stress exhibit an appropriate energy dissipation capacity, and a significant amount of transmitted lateral load will be decreased through their plastic deformation.

“…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. The Bhowmick's method provides a lower bound estimation of the SPSW structural period, which is more accurate than the equations in codes.…”

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.

In this paper, the nonlinear behaviour of steel plate shear walls with corrugated plates under lateral pushover loading conditions in the models' top level has been analytically investigated by the finite element method. The one-storey frames have beams and columns as boundary elements. Steel plate shear walls are simulated using the finite element method, based on the available experimental models in the literature. After calibration of the analytical models, more parameters of steel shear walls with corrugated plates, such as the thickness of the corrugated plate, the stiffness of the boundary elements, the corrugation depth in the corrugated plates and the corrugation length of the infill of the corrugated plates, are investigated. The results of this study have demonstrated that in the wall with constant dimensions, the trapezoidal plates have higher energy dissipation, ductility and ultimate bearing than sinusoidal waves, while decreasing the steel material consumption. KeywordsSteel shear wall; sinusoidal corrugated plate; trapezoidal corrugated plate; energy dissipation; ductility; ultimate bearing. Evaluation and comparison of behavior of corrugated steel plate shear walls 1 INTRODUCTIONSteel shear walls have been used in the construction of high-rise structures in most advanced seismic countries, such as the United States, Japan and Canada, for almost three decades. This system has great advantages compared to other similar systems such as reinforced concrete shear wall and steel braces. The benefits of this system include high ultimate bearing, perfect plasticity, high energy absorption capacity, appropriate stiffness, reduced structural weight, lower foundation construction costs, better quality and high-speed construction. The overall structures of steel shear walls consist of boundary elements such as beams and columns, with infill steel plates in the spaces between them. Steel shear walls can be constructed in two types: unstiffened and stiffened. In unstiff- ened walls, a series of flat plates with light thickness is used for utilizing the post-buckling field under overall buckling. In the second type of wall, a belt series or steel profiles are utilized as stiffeners with different arrangements -horizontal, vertical and diagonal -on one side or both sides of the wall until the energy dissipation, stiffness and ultimate bearing are increased. The first method is completely uneconomical because to improve the hysteresis curve of the walls described it is necessary to increase the thickness of the steel plate until the plate does not buckle before yielding; this increase in thickness will be very significant and uneconomical. The second method, which involves strengthening the plate by a series of stiffeners, is economical and quite effective. By using this method, the hysteresis curves turn from an S-shape to a spindle shape and increase the hysteresis curve area. However, this method, primarily due to welding operations, causes weaknesses of the plate within. It also has higher costs for j...
