预应力轻钢网格楼盖的有限元分析

On finite element analysis of prestressed light steel grid floor

利用荷载分配法把楼盖上的均布荷载分配到网格楼盖的各个节点,然后再把预应力轻钢网格楼盖结构视为单方向预应力连续梁进行了有限元模拟分析,并将利用有限元方法计算的值与理论计算值进行比较,结果表明该方法精度较高,为模拟预应力轻钢网格楼盖结构的受力性能提供了新的方法和途径。

The paper adopts the load distribution method to distribute the uniform load of the floor to all the joints for the grid floor, has the finite element simulation analysis after considering prestressed light steel grid floor structure as the single direction prestressed continuous beam, compares the value obtained by the finite element method and the theory calculation value, and it is concluded that the method has high accuracy, so as to provide the new methods and channels for the stressed performance of simulating prestressed light steel grid structure.
