| dc.description | Research on steel plate shear walls (SPSWs) was initiated in the early 1970's. In general, SPSWs system consists of a steel plate, boundary columns and horizontal floor beams. Shear buckling behavior of the steel plate is the main concern of the thin steel plate shear wall. The steel shear wall is applied in three types, stiffened, unstiffened and corrugated. The stiffened type has high stiffness, strength and amount of energy dissipated under cyclic loading. However, in the stiffened system, the construction cost is considerably higher than other types. For unstiffened shear wall researchers have found that elastic buckling is not the ultimate loading capacity of the shear panel and showed that when an unstiffened shear panel is properly designed after elastic buckling, its load bearing does not stop, and receives much greater load. Although the postbuckling behaviour of the steel shear wall causes post-buckling load bearing, this plate buckling is not favourable in any cases. Therefore, corrugated shear panel is proposed as lateral resisting system. Corrugated steel shear wall (CSSW) has higher ductility, energy dissipation capacity and toughness compared to the SPSW. However, the ultimate load of CSSW is still lower than conventional SPSW. Moreover, corrugated steel plate requires more steel material than flat plate, which increases the construction cost. To date, the behavior of the vertically-corrugated steel shear walls has not been fully studied. Thus, this study aims to investigate numerically the cyclic behavior of the vertically-corrugated steel shear walls. The corrugation angle (30°-120°), infill plate thickness (1.25, 2, and 3 mm), and the height-to-width (H/B) ratios of the walls (0.5, 0.8, and 1.2) were the parameters of this study and verified with the experimental results from previous researches. The influence of these parameters on the hysteresis behavior, toughness, and energy dissipation capacities of the CSSWs are investigated using seventy-two finite element (FE) models developed by ABAQUS. The FE results reveal that increasing the corrugation angle can improve the energy dissipation capacities and toughness of the CSSWs up to 15% and 5.8%, respectively. Furthermore, increasing the infill plate thickness and decreasing (H/B) ratios can significantly enhance the ultimate load, toughness, and energy dissipation capacities. Despite of above mentioned advantages, the ultimate load of CSSW is lower than that of SPSW. Thus, the current study proposed new hybrid corrugated infill panel models to improve the ultimate load capacity of CSSWs. The proposed hybrid infill panels were a combination of flat and trapezoidally corrugated plates. To this end, eighteen finite element FE models were established using ABAQUS. The FE results revealed that the ultimate loads, energy dissipation capacities and toughness of the proposed infill plates were up to 11.8%, 53.9% and 8.8% respectively higher than those of CSSW model with the corrugation angle of 120°.Theoretical formulae to predict the ultimate lateral shear force (Vu) of the CSSWs that have varied plate thickness and corrugation angle, as well as height to width ratios has been developed. A total of thirty-five FE models have been used to establish the empirical modification factors. The comparison results show that the new empirical formula with R-square value 0.89, Mean value of 0.98 and Cov 0.12 is reliable to determine the ultimate shear capacity of CSSWs with different configurations.,Ph.D. | - |
