- Abstract:
- The 2014 Ludian earthquake caused devastating damage to its macro epicenter,Longtoushan town.In this study,the structure information and damage states of 192 buildings in the downtown of Longtoushan(Longquan community)were sorted out and summarized.From the perspective of regional disaster prevention,the characteristics of the earthquake damage,the mechanism of disaster mitigation are studied by analyzing the buildings in Longtoushan town,and the the shelters and recovery process were examined.The function integrity index for regional buildings is proposed to evaluate the the recovery degree at different stages of time.The phenomenon that an relatively small earthquake led to serious seismic damage was primarily attributed to the local anomalies of ground motions and seismic capacity of buildings.A regular building with the necessary seismic fortification measures is largely able to avoid its collapse in an earthquake far beyond its designed fortification level.The proposed functional integrity index can reasonably describe the recovery process of regional buildings and provide a quantitative analysis on the regional seismic resilience.
