摘要
在设计大吨位的深水导管架时,依据供应商提供的木材性能参数来选取木材许用应力(主要是横纹承压)的通常做法已不能满足新的质量要求.而对于超大型导管架来说,为确保其建造和安装的顺利进行,更有必要对垫木的设计寻求规范依据.论文通过国内外两本木结构设计规范的对比,寻找合理的许用应力的取值方法,对超大型导管架下水滑撑垫木的设计提出指导性意见.
In conventional design, allowable compression stress of the timber is referenced by the data from the vendor, but which cannot meet the quality requirements with the increase in tonnage of deep-water jacket. In this paper, we propose a reasonable method to calculate the allowable stress of timber by comparing two commonly used specifications at home and abroad for structure of timber, and provide guidance designing launch cradle timber for mega jacket.
