Application of Assembled Building with Steel-structure in Earthquake-prone Areas in Sichuan Province

Abstract

Anti-seismic, energy-saving and environmental protections are the core themes of residential development in any country or region. China is one of the countries with the most serious seismic hazards in the world. The occurrence frequency of strong earthquakes is in the forefront of the world. Sichuan is located in the relatively active Eurasian seismic belt. In recent years, after the Wenchuan, Ya'an and Jiuzhaigou earthquakes, another earthquake of magnitude 6.0 occurred in Changning County of Yibin City in June 2019. Assembled building with steel-structure has the advantages of high anti-seismic property, high degree of industrial production, short construction period, energy conservation and environmental protection, convenient transportation, and fast construction speed, which can effectively protect people’s lives and property in the event of earthquake. Based on the analysis of the development status of steel earthquake-resistant structures at home and abroad, combined with the particularity of Sichuan geography and geomorphology, this paper discusses the advantages of assembled building with steel-structure in earthquake-prone areas, and the implementation methods of assembled building with steel-structure in Sichuan seismic hazard reconstruction.
