| 摘 要： | 现浇混凝土梁板式楼盖体系中,梁与板形成整体,在竖向荷载作用下共同受力.然而传统的简化分析方法很少考虑梁板的共同作用机理.本文在对现浇混凝土梁板式楼盖有限元分析的典型单元类型,即3D梁单元、膜单元、板单元及壳单元作简要概述的基础上,应用三维结构有限元程序SAP2000对典型的现浇混凝土梁板式楼盖进行建模分析,通过与传统简...

| Abstract: | Within a cast-in-place RC beam-slab floor system,beam and slab are integrated and interacts on each other upon gravity load.However,classical design approaches rarely take into consideration this coupling effect between beams and slabs.In this paper,some typical finite elements used for RC beam-slab floor analysis,including 3D frame element,membrane element,slab element and shell element are introduced,and the 3D finite element program SAP2000 is used to build and analyze some typical RC beam-slab floor.By ... |
