Parametric Sensitivity Analysis of Long-Span Arch-Truss String Structure

Abstract:

Parametric sensitivity to static behavior and dynamic characteristics of Long-span Arch-truss String Structures (ATSS), which is based on statistical distribution of parameter errors including elastic modulus of the material, effective area and pre-stress of cable, and thickness of steel pipe, etc., was studied by Monte Carlo simulation method of ANSYS. The error of sectional area of cable is found to be the most sensitive parameter and the natural frequencies are greatly sensitive to the errors of modulus of members. The results help to determine suitable updating parameters of ATSS, and provide valuable advices to guide the construction control.
