Study on Building Seismic Design Based on Mechanics Properties with Economical Assessment

A simple type of structure with two different fortification intensities was chosen to calculate, and the costs between the low intensity structure after reinforcement and the high intensity structure were compared. The possible economic losses of structures in different seismic fortification intensity was also compared in order to analysis the affect of intensity on the building economic effect. The result showed that the economic benefit of high intensity structure was 1.07, and the reinforced low intensity structure was 0.58. So the economic benefit of structure with reasonable seismic input was evident.
