约束条件对天津极地海洋馆网壳结构性能的影响
The Effect of Constraints on the Structural Performance of Tianjin Polar Ocean World's Latticed Shell
摘要
Abstract
The steel structure roof of Tianjin Polar Ocean World, based on the principle of bionics design, simulates the shape of a whale. The body of the whale is 275m in length. 117m in width and 45. 6m in height, which is simulated by a double-layer latticed shell. The dorsal fin of the whale is 69. 4m in height, which is simulated by a spatial truss. Based on the finite element analysis of the object of steel structure roof, the static characteristic, dynamic characteristics and aseismatic performance of the double-layer latticed shell in different constraints are studied in the article, in order to analyze the effect of support stiffness on the structural performance of latticed shells. The different constraints include elastic support and fixed hinge support. Compared with fixed hinge support, elastic support can remarkably improve the mechanical properties of the double-layer latticed shell roofs. The article has some theoretical value and applicable significance for related research and engineering design.关键词
