本文讨论了设置柔性横隔板的砌体结构振动台试验的相似规律。解决了两项任务。首先，本文对相似律的研究进行了文献综述。讨论的重点是柯西定律和柯西-弗劳德定律。其次，通过数值分析验证了上述两个定律的准确性和充分性。在此基础上进行了两次振动台试验，作为实例分析。本文通过对比足尺模型和缩尺模型的性能，探讨了相似律在柔性隔震砖房结构振动台试验中的理想应用。
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.
