Key Technologies and Applications for Safety Appraisal of Old Town Residential Buildings
This paper studies the key technologies for safety appraisal of old urban residential areas,including the requirements for changes in safety appraisal evaluation standards,appraisal of buildings with unauthorized demolition and renovation of walls and adding floors,and appraisal of adjacent buildings damaged by foundation pit deformation or foundation settlement.Taking a residential area in Jianye district of Nanjing City as an example,the safety performance of the residential area is evaluated and evaluated at three levels:component,subsystem,and system.Based on the safety level evaluation results of each subunit,and taking the lower level as its safety level,the safety level of the house is rated as Dsu level,which seriously affects the overall bearing capacity and requires structural reinforcement of the original structure.
