Abstract：During Sichuan Earthquake a lot of industrial buildings have be collapsed, at the same time others have be injured on several levers. Now how to evaluate reliability and fragility of the industrial buildings and search reasonable design of seismic strengthening of these reinforced concrete buildings is urgent mission. A finite element analytical model has been built in considering of building history、material difference and design configuration in Sichuan region’ industrial buildings. Meantime a uniform response spectrum of accelerations has being set up based on China Seismic Code as input seismic excitation, lead-rubber bearings have be used on base of original building as building’ strength procedure. fragility curve of two kind of building are also be drawn after carefully analysis. Inter storey ratio is decreased about 1/3 after using seismic isolation procedure. In the end some valuable conclusions also be pointed as valuable consultation for diagnose and strengthening these buildings.
