In this paper,a formula of calculating the internal force and displacements for the bend problems of rectangular plates with corner post support is given by selecting appropraite displacement functions and using Lagrange multiplier method.

Based on the test results of a largescale reinforced concrete waffle slab supported by corner columns of panels ,a calculation method of deflection from loading to failure of the structure was proposed.

Performance under force of column-supported steel silos under wind loading;

This paper sets up the finite element model of the column-supported tube filler cast-in-situ hollow floor and the corresponding solid floor,and determines the element type and mesh partition scheme.

The interaction between the structure and the beam-column supports in the form-finding process is taken into account.
