Finite element analysis software is used to apply the three-dimensional non-linear finite element method to the long-span two-way slab hollow structure, and the three-dimensional body element finite element method is used to simulate and analyze. The bidirectional slab finite element method Calculate the model. The stress distribution and force-deflection relationship of various slab structures are obtained. The yield state of the long-span two-way slab structure is obtained, and the force effects on the slab structure with different stiffness columns are compared and analyzed.
