摘要
本文通过对1/4缩尺比的二层二开间底层框架混合结构房屋的模型进行低周反复荷载作用下的试验研究,探讨了这种结构形式在地震作用下的裂缝开展过程、破坏机理、滞回特性、强度与刚度以及延性与耗能能力,并将相应阶段的试验结果与弹性有限元的计算结果进行了对比分析。
A two-story and two-space structure model (1/4 scale) is tested under low-cyclic loading for studying the antiseismic behavior of the brick building with frame on the ground floor. This paper presents mainly the development and pattern of cracks, failure mechanism,hysteresis behavior, strength and stiffness, ductility and energy dissipation. The calculated results by elastic finite elemet method are also compared with the results of test.
