Abstract_Chinese:为有效降低导管架平台上部组块重量, 针对导管架平台120人生活楼结构, 提出生活楼外壁取消斜撑、直接采用波纹板进行承载的结构设计方案．针对生活楼局部框架波纹板模型, 探讨SACS模拟波纹板结构的方法和波纹板网格划分密度, 在此基础上, 采用SACS建立生活楼整体结构的有限元模型, 对88种载荷组合工况进行计算, 引入强度增强系数和刚度增强系数, 深入分析对比波纹板与斜撑对生活楼结构的强度和刚度贡献．结果表明, 波纹板对结构的刚度贡献大于斜撑, 对大部分杆件的强度贡献亦大于斜撑, 因此在考虑波纹板承载的基础上, 生活楼外壁取消斜撑的结构设计方案是可行的．
Abstract_English:Based on a 120-people-living quarter on jacket platform，a new structural design of living quarter bulkhead that corrugated panels were directly used to carry loads instead of diagonal bracings was proposed in order to decrease the weight of topside. Based on a local corrugated frame panel，the method of modeling a corrugated panel and the mesh size of finite element in SACS were discussed. Furthermore，three kinds of finite element model of the whole living quarter were built by SACS and structural stress and deformation were analyzed under 88 kinds of load combinations. In order to make a comparison of contribution to structural strength and stiffness between corrugated panel and diagonal bracing，strength enhancement coefficient and stiffness enhancement coefficient were introduced. The analysis showed that the stiffness contribution rate of corrugated panels was slightly bigger than that of diagonals bracing and the strength contribution of corrugated panels to most of beams was also bigger than that of diagonal bracings. Generally，the structural design of living quarter bulkhead was feasible.
