Calculation method of lateral stifness of combined rubber bearing and serial system of bearing with columns;

Bridge isolation with SMA-composite rubber bearing;

By using the proposed SMA-composite rubber bearings,the time-history analysis of a standard-span girder of a multi-span simple bridge excited by three kinds of earthquake wave that respectively denote three sorts of ground frequency is simulated,and the isolation effects are compared with those of the or- dinary rubber bearings.

This thesis presents a study of seismic isolation of long-span spatial structures using SMA-rubber composite bearing.

Combining with construction of composite rubber bearings in danger building reconstruction engineering at 12 block 3 area of Sanlihe in Beijing,ideas and key points of technical quality management for isolation system construction are discussed.

Analysis of doule-direction earthquake rubber support base earthquaking process;

Started from problems in summarizing bridge surface shrinking cracks,it analyzes and elaborates the key skilled problems of multi-hole bridge such as top force analysis,bottem structural block and soft supporting s combination as well as kinds of rubber supporting and rational usage.
