Abstract

Due to design considerations, reinforced concrete (RC) shear walls, with narrow cross-sections containing excessive steel reinforcing bars, are commonly used in tall buildings for seismic resistance to produce functional floor plans. However, as is particularly evident in the end region components of the RC shear walls, bulky reinforcement can lead to difficulties in concrete pouring and cause concrete segregation. Accordingly, this study concentrates on the numerical investigation of composite shear wall behavior created using cold-formed steel sheet (CFSS) elements under cyclic loading. Three composite shear wall test specimens, having L-shaped CFSSs utilized in the shear wall end regions, were modeled on a 1/3 scale with ABAQUS finite element analysis software. The specimens’ crack propagation behavior was investigated at each loading stage in the numerical analyses and validated with experiments. Furthermore, the lateral force-top displacement relationship was used to assess the wall’s behaviors. According to the results, the modeling approach accurately simulates the composite shear wall’s behavior. Finally, a parametric analysis was performed with the verified numerical simulations to examine the effect of the CFSS elements’ material properties on the composite shear walls. The parametric studies revealed that the steel sheets’ yield strength and position from the neutral axis affected the shear walls’ lateral load-bearing capacity.

对承受循环荷载的复合剪力墙行为的实验验证数值研究

出于设计考虑，钢筋混凝土（RC）剪力墙的截面较窄，含有过多的钢筋，通常用于高层建筑的抗震，以产生功能性平面图。然而，在钢筋混凝土剪力墙的端部区域构件中尤为明显的是，粗大的钢筋会导致混凝土浇筑困难并造成混凝土离析。因此，本研究集中对使用冷弯钢板（CFSS）构件制作的复合剪力墙在循环荷载下的行为进行数值研究。使用 ABAQUS 有限元分析软件对剪力墙端部区域使用 L 型 CFSS 的三个复合剪力墙试件进行了 1/3 比例建模。数值分析研究了试样在每个加载阶段的裂纹扩展行为，并通过实验进行了验证。此外，还利用侧向力-顶位移关系评估了墙体的行为。结果表明，建模方法准确地模拟了复合剪力墙的行为。最后，在验证数值模拟的基础上进行了参数分析，以研究 CFSS 元素的材料特性对复合剪力墙的影响。参数研究表明，钢板的屈服强度和与中轴线的位置会影响剪力墙的侧向承载能力。
