关于Multi-Point Response Spectrum
反映谱分析包括Single-Point Response Spectrum (SPRS) 和Multi-Point Response Spectrum (MPRS)。In a single-point response spectrum (SPRS) analysis, you specify one response spectrum curve (or a family of curves) at a set of points in the model, such as at all supports,
In a multi-point response spectrum (MPRS) analysis, you specify different spectrum curves at different sets of points。
如果地震谱在三个方向都有，且不同，但作用于一个节点上，还算是Multi-Point Response Spectrum (MPRS)吗？谢谢指导！
