摘　　要：为了研究温度对黏土砖砌体抗压性能的影响,对不同温度后黏土砖砌体试件的抗压强度进行试验,得到了砖砌体强度随温度的变化规律。试验结果表明:随着受热温度的升高,黏土砖砌体的极限荷载逐渐降低。根据砌体试件截面内各点在高温后的温度分布状况、材料高温后的性能变化规律,提出采用分层法计算得到高温后砌体承载力的简化计算方法,可为高温后砌体结构安全性评估提供参考。The brick masonry samples after different temperature were tested to investigate the influence of high temperature on compression behavior of brick masonry.The change of the brick masonry strength with temperature was gained.The results indicated that the bearing capacity of brick masonry reduced with increasing temperature.The simplified calculation on bearing capacity of brick masonry after high temperature was gained by layering,according to the temperature distribution of points in the samples at high temperature and the change of the materials properties after high temperature.The results of research can offer a support to the safety assessment of masonry structure after high temperature.
