Abstract: 

 This study explores the effect of fire time and axial compression ratio on the failure mode, skeleton curve, stiffness degradation, ductility ratio and hysteresis energy dissipation of inorganic polymer concrete short columns after fire by pseudo-static test on three short column samples after high temperature and two contrast samples at normal temperature. The results show that the increase of axial compression ratio can improve the shear bearing capacity and stiffness of inorganic polymer concrete short columns at room temperature, but the ductility and energy dissipation of the samples are reduced. The longer the fire time is, the more obviously the shear bearing capacity, stiffness and energy dissipation capacity of inorganic polymer concrete short columns decrease, and the smaller the influence on ductility is. The higher the axial compression ratio, the worse the ductility is and the easier the shear failure is. After open flame test, the higher the axial compression ratio is, the more obviously the anti-seismic property of the samples decreases. It is suggested that the axial compression ratio of inorganic polymer concrete short columns should be appropriately controlled in the fire-prone area
