The purpose of this study was to investigate the thermal and cyclic behaviors of fire-damaged walls designed with different failure modes, aspect ratios and heated areas. These cyclic behaviors include temperature distribution, maximum lateral load, stiffness, ductility, and energy dissipations, etc. Toward this goal, the concrete wall specimens were exposed to heat following an ISO 834 standard time–temperature curve and the cyclic loading was applied to the fire-damaged walls. The test results showed that exposure to fire significantly reduced the cyclic performance of the RC walls. Especially, it was observed that heated area, designed failure mode, and aspect ratio have influences on maximum lateral loads, stiffness, and ductility of the fire-damaged walls, while almost no effects of the heated area, designed failure mode, and aspect ratio on temperature distribution and energy dissipation were found.

钢筋混凝土剪力墙火灾循环性能试验研究

本研究的目的是研究设计有不同破坏模式、纵横比和受热面积的火灾破坏墙的热和循环行为。这些循环行为包括温度分布、最大侧向载荷、刚度、延展性和能量耗散等。 为了实现这一目标，混凝土墙试件按照 ISO 834 标准时间-温度曲线暴露于热中，并将循环载荷施加到被火烧毁的墙壁。测试结果表明，暴露在火中会显着降低 RC 墙的循环性能。特别是，观察到受热面积、设计破坏模式和纵横比对火灾破坏墙的最大侧向载荷、刚度和延性有影响，而受热面积、设计破坏模式和纵横比几乎没有影响。
