摘要:
单元拼装式自平衡预应力空间网壳具有连续拉和间断压的空间受力特性,其地震作用下的可靠性和性态规律尚不明确.以100跨凯威特K6型双层网壳为研究对象, 选用梁元和索元的混合有限元模型,进行了三向Kobe地震动作用下结构非线性地震反应分析.针对结构地震响应的主要影响参数,对网壳结构的地震响应规律进行了研究,获得了网壳结构的地震反应规律.分析结果表明,结构具有良好的抗震性能,网壳的矢跨比和拉索预应力是抗震设计的主要控制参数.
Abstract:
Self-balanced pre-stressed shell structure assembled with elements and the mechanical characteristics of "continuous pressure, intermittent pull", its reliability and state of the rules under Earthquake is unclear.The combined finite element model of beam elements and cable elements is selected, and the seismic analysis is carried out by method with inputting the three dimensional Earthquake Kobe for a 100m span Kiewitt (K6) double-layer grid lattice spherical shell. In addition, the rules of seismic response are system studied by means of changing the main parameters of structure, and the rule seismic response of latticed shell was obtained. Finally, the results indicate that the structure has good seismic performance. The rise-span ratio and the cross section area of cables are the main control parameters for seismic design.
