Investigation of rural hours seismic damage and countermeasure to enhance the construction quality of rural hours;

12" Wenchuan Earthquake caused many hydropower stations in seismic area being destroyed to different degree,in order to understand and master the safety status quos of Shapai Hydropower Station after earthquake occurrence and to summarize the seismic damage characteristics and anti-earthquake experience.

By the analyze the finished works in building safety app-raisal of the damaged houses in Mianzhu City and correlative regulations,the seismic damage and its causes were summarized.

Bearing capacity design formulas considering initial damage of RC frame joints strengthened with BFRP are given,thereby providing references for evaluation of bearing capacity and reinforcing design of earthquake damaged members.

The study of resistance to thermal shock of inter-type and nano/nano-type ZTM/Al_2O_3 composite;

Firstly, a simulative earthquake damage test is carried out.

Lateral displacement estimation for RC columns in different seismic damage states;

Elementary study on usefulness of carbon fiber for controlling bridge pier seismic damage;

A matter-element analysis method for seismic damage evaluation on reinforce concrete structure was presented.

Based on the Reference[1],this paper proposes the earthquake loss assessment method of typical urban building.

Then,the vulnerability classifying method for a colony of those building is also studied to provide a reference for the earthquake loss prediction and assessment of the typical urban buil.

The decision-making method of earthquake-resistant fortification standards of engineering structures, which is based on the initial cost analysis and the earthquake loss analysis of structures, is presented.
