Research on Seismic Performance and Earthquake Damage Prediction of Buildings Based on Performance Testing

Research on seismic performance of high-rise buildings, predict structural response under earthquake to reduce casualties and design seismic scheme. According to the seismic performance and seismic damage characteristics of the structure, the main factors influencing the seismic damage results of the structure are given. These main factors include the structure form, site type, construction age, building floor number and building area. Each influencing factor is quantified and given different weights according to its sensitivity, and the fuzzy analogy prediction method is adopted to predict the seismic damage of group houses. The structural finite element analysis software SAP is used to predict, analyze and calculate the earthquake damage of buildings. By calculating the inter-story displacement angle, the seismic performance of some important buildings is evaluated by simplified evaluation method. The results show that the method can meet the requirements of the compilation of comprehensive seismic disaster prevention planning for cities.
