［提要］近20年來的震害情況表明，在建筑抗震設(shè)計(jì)中不能簡(jiǎn)單地只設(shè)定以生命安全為目標(biāo)的單一抗震設(shè)防標(biāo)準(zhǔn)，而且還應(yīng)該確保地震時(shí)建筑物的正常使用功能。從介紹日本抗震設(shè)計(jì)規(guī)范的思想及其演變過程入手，重點(diǎn)介紹2000年開始實(shí)施的基于性能設(shè)計(jì)的法規(guī)，討論其對(duì)地震力和輸入地震波的特殊規(guī)定以及新驗(yàn)證方法的特點(diǎn)，為我國地震工作者和建筑抗震設(shè)計(jì)人員提供一些參考。
［關(guān)鍵詞］地震力；輸入地震波；開放型工程地基；表層地基
Computing Method of Seismic Force and Input Seismic Wave in  Japanese Structural Seismic Design Code/Pei Xingzhu1,Zhang Li2,Zhou Xiaosong2,Liao Shuqing2(1 Jiangsu University of Science and Technology,Zhenjiang 212003,China; 2 Department of Civil Engineering, Xi"an Jiaotong University, Xi"an 710049, China)
Abstract:The catastrophic of earthquake in the world over the past 20 years shows that the life safety can not simply be the only target for seismic design of buildings. The life safety and building function available during earthquake are both important. The idea of Japanese antiearthquake design code and its developing process are introduced firstly, then the seismic force and input seismic wave in performancebased design code applied from 2000 are introduced, some special conventions and new methods are also discussed principally. The research of Japanese seismic design idea is helpful, and the research can be a reference for Chinese seismologists and civil engineers.
Keywords:seismic action; input seismic wave; open engineering foundation; surface foundation
