［摘要］湛江某原料場平面為200m×595m，采用單跨結(jié)構(gòu)難以滿足要求。設(shè)計(jì)上采用兩側(cè)落地、中間設(shè)置混凝土框架支承的兩跨雙層柱面網(wǎng)殼結(jié)構(gòu)形式。采用多個(gè)空間計(jì)算程序?qū)υ摻Y(jié)構(gòu)進(jìn)行了靜力計(jì)算對比和動(dòng)力特性及抗震性能分析，并介紹了支座設(shè)計(jì)特點(diǎn)。結(jié)果表明：該原料場兩跨雙層網(wǎng)殼結(jié)構(gòu)安全可靠，具有較好的抗震性能。

Abstract: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.

Keywords:raw material yard;two-span double-layer lattice vault;static analysis;dynamic characteristics;seismic performance
