Tripartite Plot of Response Spectra [三联反应谱]

地震反应谱是结构抗震分析与设计中的重要工具。结构抗震设计中常用的反应谱主要包括位移谱Sd(Displacement Reponse Spectra)、伪加速度谱Spa(Pseudo-Acceleration Response Spectra)及伪速度谱Spv(Pseudo-Velocity Response Spectra)。当谱加速度为常数时,谱速度和周期之间呈线性关系,为沿45°斜直线方向;当谱位移为常数时,谱速度和周期之间呈线性关系,为沿-45°斜直线方向;利用上述关系,可以将位移谱Sd(Displacement Reponse Spectra)、伪加速度谱Spa(Pseudo-Acceleration Response Spectra)及伪速度谱Spv(Pseudo-Velocity Response Spectra)统一表述到4对数坐标系(Four-Way Logarithmic Graphs)中,相应的反应谱称为三联反应谱(Response Spectra Tripartite Plot)。
