SITE URGENT STRUCTURAL ASSESSMENT OF BUILDINGS IN EARTHQUAKE-HIT AREA OF SICHUAN AND PRIMARY ANALYSIS ON EARTHQUAKE DAMAGES

摘要

Several experts from Tongji University went to the disaster area of Sichuan to carry out the site urgent structural assessment on important buildings just after the event of 5.12 Wenchuan Earthquake. The buildings, which have the severe structural defect on the main structural members or the possibility of collapse or falling down of the structural members are judged to be dangerous buildings, which should be demolished soon. In this paper, the outlines of the urgent structural assessment and the structural conditions of the damaged buildings in the extremely heavy disaster area of Qingchuan County are introduced. The earthquake damaged buildings are primarily analyzed. Some suggestions are proposed to guide the site structural assessment and to enhance the seismic capacity of building structures.
