摘要: 為了驗(yàn)證抗震性能等級(jí)的標(biāo)準(zhǔn),使用設(shè)計(jì)實(shí)例比較了靜力計(jì)算和時(shí)程反應(yīng)分析的結(jié)果. 解釋了驗(yàn)證流程和分析條件,以及用于驗(yàn)證的地震波. 在這些地震波中,覆蓋層放大系數(shù)使用的是 MLIT 告示的簡(jiǎn)化法. 驗(yàn)證用地震波和實(shí)際設(shè)計(jì)使用告示波的比較表明,驗(yàn)證用地震波得到的響應(yīng)值較大,約為告示波的 1. 2~ 1. 3 倍.

Abstract: In order to verify the criteria for seismic performance grade, the results of static design and dynamic responseanalysis were compared using design examples. The verification flow and analysis conditions were explained, as well as theseismic waves used for verification. In the verification wave, the approximate value shown in the notification of MLIT wereused for the amplification factor of the surface. Comparison between the design waves in the actual showed that the dynamicresponse to the verification wave was 1. 2 to 1. 3 times severer.
