中日两国建筑抗震设计规范对比及其在大阪世博会中国馆的应用研究
Comparative study of seismic design codes in China and Japan and application in the China Pavilion at Expo Osaka
摘要
Abstract
To investigate the differences of the seismic design codes for steel structures in China and Japan,this study systematically reviews their seismic fortification objectives,design methods,and seismic action calculations,using the China Pavilion at the Osaka Expo as a case study.Designs of the China Pavilion were carried out according to the seismic parameters specified in the codes of both countries,analyzing the overall seismic performance indicators,member dimensions,and material usage under each code.Collapse fragility analyses were conducted using 11 seismic waves from the Chinese code and 7 from the Japanese code as input sets.The results indicate that Japan's first and second seismic design levels correspond to China's seismic design requirements for moderate-to-high-intensity regions under frequent and rare earthquakes.For short-period structures,the seismic actions prescribed by the Japanese code are greater in low-intensity areas,whereas those prescribed by the Chinese code are greater in high-intensity areas.For long-period structures,the Chinese code specifies lower seismic actions in low-intensity areas,with both codes prescribing similar actions in high-intensity areas.Under the same project,the member sizes and steel quantities designed according to the Japanese code are larger than those designed according to the Chinese code.For the same seismic intensity,the seismic waves selected by the Japanese code induce greater structural responses.Structures designed by the Japanese code demonstrate higher seismic performance redundancy and collapse resistance under rare and very rare earthquake conditions.关键词
