摘要:
利用ADINA有限元软件对单跨梁板式筏形基础进行了冲切模拟和非线性分析,得出了筏板基础的裂缝、变形及地基反力分布。结果表明:在小荷载情况下,筏板的地基反力分布比较均匀,随着荷载的增加,筏板的地基反力呈非线性分布并且主要集中在肋梁及其周围2.5倍板厚的范围内; 板格及肋梁都出现了反向弯曲的现象; 冲切验算时考虑了板格冲切破坏模式和节点破坏模式2种情况,并取两者的最不利值作为筏板的冲切承载力。数值模拟结果为筏板结构设计和试验研究提供了理论依据。
Abstract:
Using ADINA finite element software to carry on punching shear imitation and nonlinear analysis for single-span beam-slab type raft foundation, the fracture, the deformation as well as the distribution of foundation reaction force of the raft foundation were got. The results show that under the small load, the distribution of foundation reaction force of the raft is homogeneous, but with the increase of load, the foundation reaction force presents as nonlinear and concentrates on rib beam and its surrounding 2.5 times plate thick scope. The board and rib beam both represent the phenomenon of inverse bending. In the punching shear calculation, considering board punching shear destructive mode and node destructive mode, and taking the worst-case value as punching shear bearing capacity of the raft. The numerical simulation results can be used as theoretical basis for structural design and model test of this type of raft foundation.
