| 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. |
