用于计算单自由度结构在地震作用下的响应与反应谱-It used to calculate the response of single degree of freedom structure under earthquake response spectrum

计算地震数据的速度反应谱，以及速度反应谱谱比曲线，可用于处理地震数据，基于Fortran语言汇编(The velocity response spectrum of seismic data and the spectral ratio curve of velocity response spectrum are calculated, which can be used to process seismic data and are compiled based on Fortran lan
