摘　　要：根据钢筋混凝土框架结构的受力特点,将楼板平面内刚度无限大的假定直接用于构造适合框架结构力学分析的三维27 节点非经典超级单元. 算例结果表明,提出的超级单元减少了计算工作量,又保证了一定的精度.According to the characteristics of R/C frame structures,the hypothesis of rigid floor in plane is used for construcing 3 D non classical super element that is adapted to the mechanics analysis of frame structures.The results of numerical examples demonstrate that the proposed super element reduces the numerical working capacity and has good accuracy.A simple and versatile method of nonlinear seismic response analysis of space frames is proposed.
