According to the analysis on the factors causing damage of the hinge joints in hinged voided slab bridges, this article put forward to the plans for strengthening of a bridge under the condition of open to traffic, which include the shear steel and transversly prestressing mothods, and it gives the result evaluation for using the shear steel method.

Behavior of transversal shear steel-bar to resist shear slippage in the simple-supporting light-weight aggregate concrete composite slabs was studied.

In this article, author introduces the content and characteristic of reinforcing steel fabrication center, a new style of specialization reinforcing working method, and relative standard, technology of bar cutting, bar bending, bar straightening and welded steel fabrics, et al of this new method.

An experimental study on the aseismic behavior of hollow shear wall of reinforced concrete;

Based on the test of three reinforced concrete hollow shear walls under the action of bending moment and shear force,the failure mechanism,the deformation feature and the strain of steel bar under the horizontal loading are discussed.

Based on the test of eight reinforced concrete hollow shear walls of various slenderness ratio under the action of axial compressive force,The failure mechanism,the deformation feature and the strain of steel bar under the axial loading are discussed.
