Survey and analysis of the seismic performance of rural buildings in the south-west of the Handan area
In recent years,small earthquakes have occurred frequently in the south-west of Handan City,Hebei Province.This study takes this area as a survey area.The survey points were selected evenly to analyze the seismic performance of rural houses as a whole,taking into account the topography,transportation,village scale,and other information.According to the survey,rural houses in this area mainly have three types of structures:brick-concrete,brick-wood,and stone-wood,and the seismic performance of the houses is as follows:The stone-wood structure houses were built in the 1960s-1970s of the 20th century,and the construction quality was generally low.The seismic-resistance design was not carried out,and the seismic performance was weak.The brick-wood structure houses were built in the 1980s-1990s of the 20th century without ring beams and structural columns,and their seismic performance was poor.The brick-concrete structure houses were built in the late 1990s of the 20th century and later,and the construction quality is good.Some houses adopt seismic-resistant designs,but the seismic performance is mediocre.Given this,it is suggested that the relevant government departments should strengthen supervision,powerfully propagate seismic resistance,standardize management in combination with rules and regulations,set up a relevant housing subsidy policy,and merge or relocate villages and towns.It is necessary to effectively improve the seismic performance of rural houses to fully protect the safety of people's lives and property.
