摘　　要：通过对无机聚合物混凝土柱进行多种高温工况下偏心受压试验,研究不同温度工况对无机聚合物混凝土柱力学性能的影响;通过承载力、轴向变形、侧向挠度等指标,得出无机聚合物混凝土柱在不同温度作用下性能的变化规律。结果表明:无机聚合物混凝土试块虽在受火400℃内存在承载力强化现象,但无机聚合物混凝土柱的承载力随受火温度升高始终呈下降的趋势,在不同高温工况下,无机聚合物混凝土柱的偏压承载力损失比例均要小于普通混凝土柱,具有优良的耐火性。The influence of different temperature conditions on the mechanical properties of the inorganic polymer concrete column was studied.Through carrying capacity,axial deformation,lateral deflection and other indicators,the variation law of the performance of inorganic polymer concrete column under different temperature is obtained.The results show that the inorganic polymer concrete block has the fire phenomenon bearing capacity of reinforced with in 400℃,but the bearing capacity of the inorganic polymer concrete column affected by the fire temperature is always a downward trend,under different working conditions of high temperature,the bearing capacity of the bias of inorganic polymer concrete column loss ratio is less than common concrete column,it has excellent fire resistance.
