Abstract

Abstract: According to "unified standard for reliability design of highway engineering structures" GB/T50283-1999, the reliability of the formulas for the design of CFST beam-columns is analyzed, which is given in the "Code for design of steel-concrete composite structure" DL/T5085-1999. The result shows that the reliability of the formulas can meet the requirement of reliability index set in the GB/T50283-1999.

Key words: highway engineering, concrete filled steel tube (CFST), beam-columns, reliability

摘要： 根据《公路工程结构可靠度设计统一标准》GB/T50283-1999的规定,对《钢-混凝土组合结构设计规程》DL/T5085-1999中钢管砼压弯构件的承载力计算公式进行了可靠度分析.结果表明,其计算公式可靠指标β值都在4.2以上,满足GB/T50283-1999的要求,可供公路工程钢管砼构件设计时参考.
