A number of the critical techniques,such as the three main truss spatial structure,Q420qE high performance structural steel,plate and truss composite structure,monolithic deck structure and vibration suppression for long hangers,have been applied to the Bridge.

Experimental study and analysis on structural performance of the prestressed concrete hollow slabs with the height of 120mm;

Research on influencing of partial damage to structural performance of house;

Comparison on the structural performance of prestressed concrete frames with T-section column and with rectangular section column;

By chosing appropriate metal web,treating with the surface of the metal web,and testing the structure property and electromagnetic compatibility of the composite,the method of designing electromagnetic compatibility composite was achieved,the research result showed that the composite could meet the need of sturcture property,electromag.

In this paper, the test and analysis of LDPE structure property during capillary dynamic extrusion were carried on, and the effect of vibration force field on the structure property of the extrudate was discussed.

Refering to correlation standard, this subject discusses structure property index s determine, calcuation and drawing up test plan of restressed concrete hollowcore slab by engineering.
