Repairing and Reinforcing Scheme of Crossbeam for Bridge Approach of Binzhou Yellow River Bridge;

The breakage types of crossbeam of simply supported T beam mainly embodied with three aspects,not coplanar,height difference and damaged.

For example,the research document of the bearings and crossbeam layouts of the irregular bridge with lager ratio of wide-span and other .

Analysis of effect of the diaphragms on the typical structure of Y-shape bridge behavior subject to force;

Prestressed Construction Technology and Stress Analysis of Diaphragm in Jinma Bridge;

To comprehend the structural behavior of diaphragm,this paper analyses the structural characteristics of box girders diaphragms combined with calculation examples,the defects of the general calculation method of diaphragms are pointed out and a new calculation model is put forward.

A calculation model and method of the cross slab in the box girder is obtained by the bridge 3D-analysis of the continuous concrete box girder under dead and live load.

The prestressed concrete cross slab in box girder is regarded as a single element when calculation will be made using bridge space computation program to clarify the most unfavorable magnitude of its internal forces such as: shear stress, bending moment, etc.

Diaphragm beam is the important part of a bridge,which makes the vertical beam and cross beam work together.

The paper introduces the simplified calculation method of diaphragm beam section of box beam at piers and abutments.

The primary of the analysis include the lateral force in the top deck of box girder and the lateral force of the diaphragm beam on the pier.

This paper expounds the hazard of T-beam cross diaphragm s dislocation,analyzes the causes,and puts forward the controlling principle;It is pointed out that cross diaphragm oblique angle design is one of the key means of controlling the dislocation.
