Abstract

Simulations of local compression on the centers of plain concrete square columns with rebar meshes and plain concrete square columns were conducted by means of the finite element analysis software ANSYS. The results show the distributions of longitudinal stress is basically consistent between the plain concrete column and the plain concrete columns equipped with rebar meshes. Increased stress concentration phenomena of load bearing surface, with the load increases. Local compression area ratio affect the rate of diffusion of longitudinal stress, In the vicinity of the pressure surface, local compression area ratio increases, the peak stress in-creased considerably, and local compression bearing capacity is reduced.
