Abstract: An investigation on the damage of an industrial building of 24 tank bodies upperly supported on the reinforced concrete frame in Wenchuan Earthquake was made in this paper, and the cracking causes of maintairing walls and base concrete of tank body were analyzed. The analysis of complicated spatial structural system made up by tank bodies considered (with 480t of total weight of equipment and liquid) and single frame structure at the bottom was made under seismic action, and the characteristics of earthquake responses were studied under the conditions of empty-tank and full-tank The seismic strengthening suggestions were proposed for this project with meeting the requirement of seismic fortification intensity 6 and 7.
Keywords: 24 tank bodies; seismic strengthering suggestions; analysis of seismic damage
