摘要
镇江某温室钢结构采用异形单层网壳结构,网壳杆件截面为矩形管。在设计时采用数道横向空间桁架及]道环向空间桁架对网壳进行加强。对采用加强桁架的异形单层网壳进行了整体分析,结果显示其各项性能指标满足规范要求,结构整体受力特点仍接近网壳,加强桁架的杆件内力差异大于网壳杆件。
Irregular single-layer lattice shell structure is adopted in a greenhouse building in Zhenjiang. The section of the shell member is rectangle tube. The shell is strengthened by space trusses consisting of several transversal trusses and a ring truss. Overall analysis to the strengthened shell shows that all performance indicators meet the demands of design codes. The mechanical characteristic of the structure is similar to lattice shell, and the internal force difference of strengthening trusses is larger than that of shell members.
