摘要
湛江某原料场平面为200m×595m,采用单跨结构难以满足要求。设计上采用两侧落地、中间设置混凝土框架支承的两跨双层柱面网壳结构形式。采用多个空间计算程序对该结构进行了静力计算对比和动力特性及抗震性能分析,并介绍了支座设计特点。结果表明:该原料场两跨双层网壳结构安全可靠,具有较好的抗震性能。
The plane size of a raw material yard in Zhanjiang is 200m × 595m and the single-span structure could not meet the requirements.The double-layer lattice vault with two-span was used in the design which was consisted of two double-layer lattice vaults landing on both sides and concrete frame in the middle.The structure was calculated by many space calculation programs,the dynamic characteristics and seismic performance of the structure were analyzed,and the characteristics of supports were introduced.The results show that the structure of the raw material yard is safe and reliable.And it has good seismic performance.
