The further study of engineering mechanics is made for upsetting a square body between commonflat platens based on the study of upsetting a cylinder between flat platens[1,2,3],and two new mechanical models is proposed, which has been satisfied by experiments.

In order to investigate the compression capacity and mechanical behavior of high-strength concrete square columns confined with CFRP under axial load,twenty four square columns reinforced with CFRP were tested experimentally.

In this paper, the behavior of square columns, rectangularcolumns and reinforced concrete (RC) shear walls confined by CFS are studied.

Twenty four square columns reinforced with CFRP were tested experimentally under axial load to evaluate their capacity and ductility ability.

In this paper,the behavior of rectangular columns confined by CFS are studied.

The flow around a square cylinder at Re=22 000 is simulated with large eddy simulation(LES).

Influence of artificial lateral boundary conditions on numerical simulations was studied for incompressible flow around a square cylinder in a 2 dimensional unbounded domain (Reynolds number is 100).

Five reinforced concrete(RC) short square columns are tested under cyclic loading to investigate the seismic performance of short columns strengthened with CFRP composites in this paper.
