A precise algorithm for weighting functions interpolating, integrating and differentiating digital strong motion data

Zhang Xiao-zhi, Xie Li-li (Institute of Engineering Mechanics, China Seismological Bureau, Harbin 150080, China)  
In the present method of strong motion data processing, integration and differentiation are frequently used. However, usually the existing methods involve various errors. In this paper, the strong motion data are assumed to be accordance with the sampling theorem and a precise algorithm is established as a basis for various calculation involved in strong motion data processing and structural dynamic analysis.
