摘要
根据广义Clough模型建立了考虑几何非线性和材料非线性的有限元程序，并通过与实验数据的对比证明了该有限元模型的合理性和程序编制的正确性。该程序较好地反映了钢框架在火灾作用下结构的位移及内力并判断出钢框架抗火的极限温度。
According to the generalized Clough model, the nonlinear FEM program which considers the geometrical nonlinearity and material nonlinearity was developed, and the reasonability of this FEM model and correctness of the program were verified by comparison with experimental data. By using this program, the internal force and the displacement of the structure at the specific moment in fire can be obtained and the limiting temperature can be determined.
