摘　　要：运用大型通用有限元软件PATRAN-NASTRAN,建立了无梁空心板的三维有限元分析模型,并对其进行了竖向荷载作用下的非线性分析,给出了一些关键部位的荷载挠度曲线以及钢筋的应变曲线,最后将计算结果与试验结果作了对比,验证了有限元数值模拟的有效性及参数选取的合理性.The finite clement 3 - D model about Cast - in - Place RC Hollow Flat Slab with Patran - Nastran is established in this paper, so the nonlinear characteristics under vertical loading are analyzed. Some representative load - deflection curve and strain curve of reintbrcing steel bar are provided. Then the results of analysis and the results in the reference document are compared so that the validity of the finite element analysis and the rationality of the parameter used in the analysis are proved.
