ABSTRACT

This paper studies the seismic performance of precast concrete shear walls with horizontal bolted joints. A fiber-based finite-element analysis (FEA) model was developed to simulate the seismic behavior of the walls. The numerical results were verified by the experimental results of the walls. Applying the proposed FEA model, a parametric study was conducted to research the effect of main structural factors on the shear walls. By analyzing the failure mechanisms of the walls, a simplified model was proposed to predict the ultimate capacity of the shear walls with bolted connections, which was verified with good accuracy.

地震荷载作用下水平螺栓连接预制混凝土剪力墙的数值分析

摘要

本文研究了水平螺栓连接预制混凝土剪力墙的抗震性能。开发了基于纤维的有限元分析 (FEA) 模型来模拟墙体的地震行为。数值结果得到了墙体实验结果的验证。应用所提出的有限元分析模型，进行了参数化研究，以研究主要结构因素对剪力墙的影响。通过分析墙体的破坏机理，提出了一种简化的模型来预测螺栓连接剪力墙的极限承载力，并得到了较好的验证。
