摘　　要：火灾情况下钢筋混凝土构件可有不同的受热面 ,其力学性能的差别很大。通过恒温加载试验比较了两面和三面高温下钢筋混凝土压弯柱的各种性能 ,包括截面温度场、变形和极限承载力等。进一步揭示了不同温度场对钢筋混凝土构件性能的影响 。There are great differences in the mechanical behaviour of the RC members that have different surfaces heated under fire.The present paper compares the behaviours, including section temperature field,deformation and ultimate load capacity, of RC eccentrical compression members with two surfaces heated and that with three surfaces heated.It illustrates the effect of different temperature fields on the behaviour of the RC members further and provides a basis for the theoretical analysis of a structure under high temperature.
