摘　　要：由于对上部平台结构的重量控制越来越严格,采用高强度小梁替代低强度小梁是可采用的一项降低重量的措施,但工程实施中往往效果并不理想。从结构校核规范着手,给出了常用规格小梁的受弯容许应力,比较了采用高强小规格梁替代后的受弯容许应力变化,并对其在平台结构中的应用提出了建议。The weight control of topsides is more and more strict,and using high-strength secondary beams instead of lowstrength secondary beams is a feasible measure to reduce weight,but the effect of the application is often not obvious.According to the structure check codes,the allowable bending stress of commonly used secondary beams is given,and the changes in allowable bending stress after replacing high-strength secondary beams are compared.Suggestions are also made for their application in platform structures.
