一种非四周受火后混凝土柱拟静力试验装置及其实现方法

本发明提出一种非四周受火后混凝土柱拟静力试验装置及其实现方法，该试验装置的炉体的第四面炉壁根据混凝土柱的受火方式由两块活动炉壁加上中间开口部分砌筑临时性填充墙组合而成。炉体设置在反力架的架体内，竖向荷载加载装置安装在中间横向钢梁底面用以对混凝土柱施加竖向荷载；水平拉压伺服加载装置安装在水平反力墙上，可在受火后对混凝土柱试件施加推覆荷载和低周水平反复荷载。通过该试验装置对持荷混凝土柱先进行非四周受火方式下火灾试验，熄火冷却后再进行拟静力试验，数据采集系统用于采集各测点的气压、温度、位移和荷载。本发明适用于三面、相邻两面、单面等非四周受火方式下混凝土柱耐火性能和灾后抗震性能的试验研究。 The invention provides a pseudo-static testing device for concrete columns after non-peripheral fire exposure and an implementation method thereof. According to the fire exposure of a concrete column, two movable stove walls plus a temporary filling wall built in the middle opening are combined to form a fourth stove wall of a stove of the testing device. The stove is arranged in the body of a reaction frame, and a vertical load application unit is mounted on the bottom of a middle horizontal steel beam to apply vertical load on the concrete column; and a horizontal tension-compression servo loading unit is mounted on a horizontal reaction wall, and can apply pushover load and low-cycle horizontal reversed load on the c
