A constitutive relationship for predicting the response of concrete subjected to uniaxial tension-compression fatigue loading is established based on the continuum damage mechanics.

The fatigue tests on axial tension an d tension-compression under consta nt amplitude cyclic loading have been carried out on plain concrete in this paper against the fatigue state of te nsion-compression in prestressed c oncrete bridges,and the test results are compared with those obtained by other researchers and code for design.

Experimental study of mass concrete under biaxial compression-tension and triaxial compression-compression-tension stresses;

In the light of the state standards and test methods,splitting tensile strength and compressive strength of 16 different groups of hybrid fiber(containing steel fiber and polypropylene fiber) reinforced concrete specimens are tested.

This paper presents an experimental study on the splitting strength and compressive strength of hybrid fiber reinforced HPC evaluation of ratio between splitting tensile strength and compressive strength for hybrid fiber reinforced HPC.

The application of several new techniques,including hydraulic pressure drawing,inside tube high pressure forming and hot forming,in the shaping of automotive stamping parts were presented.
