ABSTRACT

This paper proposes a novel semi-rigid rocking wall-floor connection. To study its seismic behavior, a preliminary study using finite element modeling (FEM) has been conducted to perceive the rocking wall response towards the precast plank before conducting a physical experimental testing in the laboratory. The finite element model was developed to investigate the lateral quasi-static-load response of the isolated rocking wall system. Subsequently, the rocking wall model was further extended by incorporating a precast concrete plank using the proposed connection. The finite element model of the rocking wall showed a good correlation with the analytical model. Furthermore, the study showed that a semi-rigid connection would result in an overstrength that should be considered when designing the rocking wall.

摘要

本文提出了一种新型的半刚性摇摆墙-地板连接。为了研究其抗震性能，在实验室进行物理实验测试之前，使用有限元建模 (FEM) 进行了初步研究，以感知摇摆墙对预制板的响应。开发了有限元模型来研究隔离摇摆墙系统的横向准静态载荷响应。随后，通过使用建议的连接方式结合预制混凝土板，进一步扩展了摇摆墙模型。摇摆墙的有限元模型与分析模型显示出良好的相关性。此外，研究表明，半刚性连接会导致强度过大，在设计摇摆墙时应予以考虑。
