Research On Evaluation And Comparison Of Seismic Performance In China’s Rural Residential Buildings

China is one of the countries affected by earthquake most heavily. Our countrylocated in the southeast of the Eurasian plate. Due to the impact of Himalayan seismicbelt and the circum-Pacific seismic belt, China’s earthquakes is frequent and strong.At present, China’s population in rural areas is about800million, of which about80percent lives in seismic hazard zone where’s basic intensity is Ⅵ degrees and above.Both the level of social development or the level of economic development in ruralareas are relatively backward compared with that in rural areas, at the same time, theawareness of preventing and reducing disaster is relatively weak.China is an earthquake-prone country; rural areas were affected heabily in theprevious earthquakes. China is vast and the population in rural areas is relatively large.Rural housing is fundamental to the survival of farmers. But the work on preventingand reducing earthquake disaster of rural residential buildings is relatively weak. Sothe earthquake disaster prevention of rural residential buildings is worth attention.Also, due to the geographical differences, the seismic performance of rural residentialbuildings in various areas is different. Make analysis to understand their specificcircumstances, which has certain reference in the future work of earthquake disaster.This paper evaluates rural residential buildings’ seismic performance in variousareas of China based on the entropy method and gray clustering method. On the basisof substantial theoretical research and analysising120surveys of seven regions, makethe comprehensive evaluation of rural residential buildings’ seismic performance.1) See literature on earthquake disaster prevention and summarize the researchprogress in this area. Combined with rural residence, and relevant norms earthquakedamage ever recorded, summarized the concepts and definitions of rural residence anddamage performance. The same time, make analysis of recent earthquake disaster inearthquake closeness rank correlation region and from rural residential the differentangles to make detailed structural damage analysis. 2) On the basis of the seismic damage analysis combined with the properties ofrural residential buildings, build seismic performance evaluation system of ruralresidential buildings; build seismic performance evaluation model of rural residentialbuildings based on the entropy method and gray clustering method.3) Analyse the precent situation of China’s rural residential buildings from thethree aspects of construction era, structure type and layers’ number. Come to that thedistribution characteristics of China’s rural residential buildings in every region fromthese three aspects. Reference to the evaluation and comparison of seismicperformance in China’s rural residential buildings4) Make seismic performance calculation of rural residential buildings using theevaluation model. Do comparative analysis of rural residential buildings in everyregion based on the consolidated results. Come to the conclusion on the whole that thebest and the worst seismic performance of rural residential buildings are northeastregion and southwest region. Analysis the rural residential buildings’ conditions inseven regions and the relative ranking of their situation compared with other regionsfrom various indicators.
