Typical seismic damage analysis of single-story reinforced concrete industrial buildings in the Wenchuan earthquake

According to the damage survey and analysis for the single-story reinforced concrete industrial buildings located in Jiangyou,Chengdu,Pengzhou and Mianyang in Sichuan Province,Tianshui in Gansu Province,and Hanzhong in Shanxi Province,the following conclusions are derived: first,the main structures of reinforced concrete buildings designed according to the Seismic Code received minor damage;non-structural components,especially the end bays in the longitudinal direction,high gables,the cantilevered walls between two span with different height and the connection between huge device and foundation,suffered relatively serious damage;third,the structures without standard design according to the Seismic Code,as well as the old industrial buildings without consolidation were damaged severely.Thereby,the seismic design for non-structural components and huge devices should be emphasized.Moreover,the old industrial buildings that used to be designed without following the Seismic Code should be retroffited as soon as possible.
