自从Biot和Housner等人提出反应谱的概念以来,受到了各国专家和工程师的普遍重视,推动了强震观测和结构动力分析的研究工作,并为抗震设计直接建立在强震地面运动的基础之是创造了条件。我国先后颁发试行的若干专业性的抗震设计规范,都是以反应谱理论为基础的。近几年来,我们对规范中设计反应谱的若干具体问题进行了研究,新规范据此作了相应的修改。 Since Biot and Housner et al. proposed the concept of response spectrum, they have received widespread attention from experts and engineers from various countries, promoted the research of strong earthquake observation and structural dynamic analysis, and established the foundation for strong earthquake ground motion for seismic design. It is the creation of conditions. China has issued several trials of professional seismic design specifications that are based on response spectrum theory. In recent years, we have conducted research on specific issues in the design response spectrum of the specification, and the new specification has been accordingly revised accordingly.
