Abstract: The upper part of Yellow River Estuary Model Testing HallA is triple-layer space truss structure ( some part is fourfold-layer truss), and the lower part of the supporting system consist of 26 reinforced concrete columns. The structural system, mechanical characteristics and the load of the whole structure are described. Static analysis, dynamic analysis and seismic analysis are camed out. Seismic performance of the structure under frequent and rare earthquake are studied. Through the analysis the weak points of the structure are pointed out, and the result can provide reference for similar projects.
Keywords: large span triple-layer space truss structure; elasto-plastic time-history analysis; seismic performance
