GB150、ASME和JIS标准拉撑结构设计规范对比

Comparison of Braced or Stayed Structure Design Methods in GB 150, ASME and JIS Standards

拉撑结构作为GB 150—2011的新增内容,很好地解决了按照GB 150—1998标准设计带支撑的凸形封头、平封头及筒体计算厚度过大的问题。根据GB 150—2011标准释义的解释,该部分内容的制定参照了ASME VIII-1 UG-47、UG-48、UG-50、UW-19、JIS B 8267和HG/T 20583—2011的相关内容。对GB150、ASME和JIS标准拉撑结构设计规范进行对比,找出其中的共同点和不同之处,方便设计人员更加清楚地理解拉撑结构设计要点。

As a new part of GB 150-2011,the design method for stayed structure has solved the problem of quite large thicknesses of stayed convex heads,flat head and cylinder resulted from using the method in GB 150-1998.According to the interpretation of GB 150-2011,this method is referenced from the corresponding contents in UG-47,UG-48,UG-50,UW-19 in ASME Ⅷ-1,JIS B 8267 and HG/T 20803-2011.Thus,in this article,the design methods for stayed structure in GB 150-2011,ASME Ⅷ-1 and JIS were compared.The same and different points were indicated so as for designers to clearly understand the major points in designing stayed structure.
