ABSTRACT

This study experimentally investigates the reliability of testing idealized prisms to simulate failure mechanisms in RC walls. In-plane cyclic tests on three flexural walls with different transverse reinforcement detailing and axial tests on three rectangular RC prisms idealized as wall boundary zones are conducted and the experimental responses are discussed in this paper. The results confirmed that idealized rectangular RC prisms are susceptible to failure due to the development of global out-of-plane (OOP) instability. These investigations revealed that strain distribution along the height is a key parameter influencing the failure mechanism observed in wall boundaries and idealized prism specimens.

摘要

本研究通过实验研究了测试理想棱镜以模拟 RC 墙的失效机制的可靠性。对三个具有不同横向钢筋细节的受弯墙进行了平面内循环试验，并对三个理想化为墙边界区域的矩形 RC 棱柱进行了轴向试验，并讨论了实验响应。结果证实，由于全局平面外 (OOP) 不稳定性的发展，理想化的矩形 RC 棱镜容易失效。这些研究表明，沿高度的应变分布是影响在壁边界和理想棱镜试样中观察到的破坏机制的关键参数。
