A Study on Performance of Long-span Double-layer Cylindrical Reticulated Shell Structure

WANG Shuai，YIN Yue2，YANG Xin1 （1.TianjinMunicipalEngineeringDesign&ResearchInstituteCo.Ltd.，Tianjin3Oo392，China;2.ScholofCivilEnginering， Tianjin University，Tianjin 300072，China） 【Abstract】：Inordertostudythe stabilityof long-span double-layer cylindrical reticulated shellstructure，awarehouse of Shougang Jingtang United Iron & Steel Co.，Ltd.was taken as an example.The influence of diffrentload distributions on the structure is analyzed byusing the structural design software midas GEN，and the frequent earthquake response analysis of the reticulated shellstructure was conducted.The general finite element analysis software ABAQUS was employed to analyze the entire load-displacement process of the structure，and the results of the fullelastic process analysis was obtained.These results demonstrate thatthe double-layer cylindrical reticulated shell exhibits excellent overall stability.

雙層網(wǎng)殼結(jié)構(gòu)是將桿件沿著曲面有規(guī)律地布置而組成的空間結(jié)構(gòu)體系，其受力特點(diǎn)與薄殼結(jié)構(gòu)類似，大部分荷載由網(wǎng)殼桿件的軸向力承受，結(jié)構(gòu)簡(jiǎn)單，傳力明確，跨越能力強(qiáng)。（剩余4572字）
