UPPER BOUND SEISMIC LOADS ON SUPPORTING FRAMES OF SPATIAL BROKEN PIPELINES

Wang Qianxin Liu Chunguang(Institute of Engineering Mechanics, State Seismological Bureau)  
The conventional methods will never be valid to calculate the seismic responses of supporting frames under the condition of unknown rigidity distribution of the pipelines. In this paper, an approach with novel idea is presented. The upper bound seismic responses can be determined by putting the product function specially defined in this paper in extrema. Only two modes which have contributions to the responses need to be considered in design,as all the other high modes have strictly no contributions.
