Abstract

The invention discloses a method and device for analyzing the nonlinear process of earthquake response of urban building groups. The method comprises the following steps of: collecting building data;obtaining models corresponding to the building data according to the building data; establishing a multi-particle shear series model or a multi-particle parallel shear bending coordination model corresponding to the building data according to the models corresponding to the building data; through the multi-particle shear series model or the multi-particle parallel shear bending coordination model,carrying out nonlinear process calculation according to acceleration time history data of earthquake ground motion, which are input by the buildings to obtain nonlinear process calculating results; and obtaining the earthquake damage state and analysis results of each floor of each building according to the nonlinear process calculation results. The method has the advantages that the earthquake damage characteristics of buildings at different heights can be accurately reflected and are closer to the actual earthquake damage; and the method is high in calculation efficiency and simple in modeling method and can be used for accurately and timely predicting and analyzing the earthquake damage of urban typical earthquake scenarios.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method and device for analyzing the nonlinear history of earthquake response of urban building groups. Background technique [0002] Earthquakes occur frequently in our country, and a large number of densely populated cities are located in high-intensity areas. Once an earthquake occurs, it will cause serious casualties and economic losses. In order to reduce urban economic losses and casualties caused by earthquakes, it is particularly important to reasonably predict the seismic swarm response of urban buildings. [0003] The current seismic damage analysis methods for urban building groups are mainly: vulnerability matrix method and capacity spectrum method. The vulnerability matrix method is only suitable for areas with rich seismic damage data, and is not suitable for promotion; the capacity spectrum method is difficult to consider the influence of the time-domai...
