Vulnerability evaluation of high-rise earthquake-proof buildings in high-pressure area

Abstract

In order to solve this problem, the vulnerability evaluation method of high-rise seismic buildings in high-pressure area based on fuzzy comprehensive evaluation is proposed. According to the knowledge of earthquake engineering, the relationship between magnitude and intensity and the law of intensity attenuation are analysed. Based on the seismic risk and the vulnerability of the isolation layer of the building structure, the failure evaluation criteria are established. The evaluation indexes of structural vulnerability are selected, and the weight coefficients of each index are determined by using tomographic method, and the corresponding matrix is obtained. The fuzzy comprehensive evaluation method is used to evaluate each index. According to the fuzzy relation matrix and index weight coefficient matrix of evaluation index and vulnerability level, the vulnerability of building structure is calculated and evaluated. Experimental results show that the evaluation performance of this method is better than that of the experimental comparison method.
