Seismic Resistance Characteristics of Buildings in Chuxiong Yi Autonomous Prefecture Based on High-Precision Building Data
摘要
Abstract
Based on the high-precision data of building reinforcement projects in earthquake prone areas of Yunnan Province and the first comprehensive natural disaster risk survey project,the seismic hazard risk level of individual buildings in Chuxiong Yi Autonomous Prefecture was calculated,and the development of the reinforcement project of housing facilities in Chuxiong Yi Autonomous Prefecture was statistically analyzed.Through spatial comparison,the seismic resistance characteristics of buildings in Chuxiong Yi Autonomous Prefecture were analyzed.The results show that the seismic hazard level of buildings in Chuxiong Yi Autonomous Prefecture is relatively high,with the exception of urban residential buildings,which have a general hazard level,and the hazard level of other types of buildings being key.The number of building facility reinforcement projects in Chuxiong Yi Autonomous Prefecture exceeds 8.7%of the total number of buildings.The implementation of building facility reinforcement projects has effectively improved the overall seismic capacity of regional buildings,but it is still necessary to strengthen the reinforcement work of buildings with general hazard levels in the region.The collection of seismic fortification information for building facilities is the key link in accurately grasping the base of the hidden danger of earthquake disasters risk in buildings,and the timeliness and authenticity of data collection should be ensured.关键词
