Abstract

Corrugated steel plate shear walls (CSPSWs) can be applied to high-rise building structures to serve as lateral load-bearing and energy-dissipating members. Arranging stiffeners on corrugated steel plates shows substantial potential to further improve the seismic performance of ordinary CSPSWs. This study experimentally and numerically investigated the hysteretic behavior of unstiffened and stiffened CSPSWs. Cyclic quasi-static tests were conducted on four, 1/2-scale, two-story, single-bay specimens with different corrugation orientations, including two specimens with unstiffened corrugated steel plates and two specimens installed with stiffened corrugated steel plates equipped with two pairs of stiffeners. According to the hysteretic curves of different specimens, the effects of corrugation orientations and arrangement of stiffeners were revealed in terms of the skeleton curves, energy-dissipating capacity, and stiffness degradation. Then, finite element (FE) models, which were applied to gain a deeper understanding of the experimental results, were established, and validated against the test results. This study demonstrated that the arrangement of stiffeners was effective in improving the seismic performance of CSPSWs regarding the ultimate shear strength and energy-dissipating capacity, while the influence of corrugation orientations on the performance of the specimens involved in this study could be ignored.

不同波纹方向加劲波纹钢板剪力墙循环行为的实验和数值研究

波形钢板剪力墙（CSPSWs）可应用于高层建筑结构，作为侧向承重和耗能构件。在波形钢板上布置加劲件可进一步提高普通 CSPSW 的抗震性能。本研究通过实验和数值方法研究了未加劲和加劲 CSPSW 的滞回行为。在四个 1/2 比例的两层单榀试件上进行了不同波纹方向的循环准静力试验，其中两个试件采用非加劲波纹钢板，另两个试件采用加劲波纹钢板，并配有两对加劲件。根据不同试样的滞回曲线，从骨架曲线、能量耗散能力和刚度退化方面揭示了波纹方向和加劲件布置的影响。然后，建立了有限元（FE）模型，用于深入理解实验结果，并根据测试结果进行了验证。该研究表明，加劲件的布置能有效改善 CSPSW 在极限剪切强度和能量耗散能力方面的抗震性能，而波纹方向对本研究中试件性能的影响则可以忽略不计。

期刊介绍： Earthquake Engineering and Structural Dynamics provides a forum for the publication of papers on several aspects of engineering related to earthquakes. The problems in this field, and their solutions, are international in character and require knowledge of several traditional disciplines; the Journal will reflect this. Papers that may be relevant but do not emphasize earthquake engineering and related structural dynamics are not suitable for the Journal. Relevant topics include the following: ground motions for analysis and design geotechnical earthquake engineering probabilistic and deterministic methods of dynamic analysis experimental behaviour of structures seismic protective systems system identification risk assessment seismic code requirements methods for earthquake-resistant design and retrofit of structures.
