摘要
为探究山西传统民居在地震灾害下的抗震性能.文中通过将传统民居与现代民居的抗震性能进行对比,找寻传统民居在地震作用下响应规律,为传统民居的抗震加固提供理论依据.采用有限元软件ABAQUS计算模态及不同震级下破坏形态、结构损伤等内容.结果表明传统民居的振型频率较低,整体刚度较小,导致其在地震中更易受到影响.由于建造方式、材料选择和结构形式的差异,传统民居的抗震性能明显不如现代民居.在地震作用下,传统民居的位移响应和加速度均较高,且易发生地基边缘损坏,导致其整体性明显减弱,抗震性能降低.
Abstract
The purpose of this study is to deeply explore the seismic performance of traditional houses in Shanxi province under earthquake disasters.By comparing the seismic performance of traditional houses with that of mod-ern houses,the response law of traditional houses under earthquake is found,which provides a theoretical basis for the seismic reinforcement of traditional houses.The finite element software ABAQUS is used to calculate the modes,failure forms,and structural damage under different earthquake magnitudes.The results show that the vibration fre-quency of traditional houses is low and the overall stiffness is small,which makes them more susceptible to earth-quake.Due to the differences in construction methods,material selection and structural forms,the seismic perfor-mance of traditional dwellings is obviously inferior to that of modern dwellings.Under the action of earthquake,the displacement response and acceleration of traditional houses are both high,and the ground edge damage is easy to occur,which leads to the obvious weakening of their integrity and the decrease of seismic performance.
