ABSTRACT

The present paper discusses similitude laws employed for the shaking-table tests of masonry structures with flexible diaphragms. Two tasks are tackled. First, the paper presents a literature review on similitude laws. The discussion focuses on Cauchy and Cauchy-Froude laws. Second, numerical analysis is performed to examine the accuracy and adequacy of the aforementioned two laws. Two previously performed shaking-table tests are taken advantage of as the case studies. The paper explores the ideal applications of similitude laws to the shaking table tests of masonry structures with flexible diaphragms by comparing the behaviour between full-scale prototypes and reduced-scale models.

摘要

本文讨论了用于柔性隔膜砌体结构振动台试验的相似定律。解决了两个任务。首先，本文对相似法则进行了文献综述。讨论的重点是 Cauchy 和 Cauchy-Froude 定律。其次，进行数值分析以检验上述两个定律的准确性和充分性。两个先前执行的振动台测试被用作案例研究。本文通过比较全尺寸原型和缩小比例模型之间的行为，探讨了相似定律在柔性隔膜砌体结构振动台试验中的理想应用。
