Sensitivity Analysis of CFST Frame Sidesway Based on Correlation

Abstract:

This paper focused on sensitivity analysis about CFST frame sidesway (concrete-filled steel tubular) according to mutual relationships between variables. Two specimens were tested by incremental loading and cyclic loading. The finite element package ANSYS was used to study the nonlinear behavior of such specimens. The model was validated by comparing the computed values with experimental results. The probabilistic sensitivity analysis of CFST frame sidesway was carried out based on correlations in variables of the frame sidesway. Interlayer spacing was important sensitive parameter for frame sidesway. Good agreement between sensitivity analysis and mechanical formulation of lateral rigidity was observed.
