Material models are the base of computer simulation
analysis of structure. Many confined concrete
models have been put forward until now; however, there are few comparative studies on effect of confined concrete
models on structural member
analysis. In this paper, four models are selected as the representatives and applied to nonlinear analysis
program for space frames which is based on the beamcolumn element using the finite element flexibility method and the fiber model. Park’s test on columns that are combined axial and bending under monotonic loading are taken as the calibrations, comparisons to material and structural member
level are drawn and the analytical results of various models are
discussed. From this study it is concluded that despite the significant difference in the stress-strain curve of each confinement model the difference in structural member
analysis reduces obviously but still remarkable. The simulation
using Mander model shows better agreement with the experimental results.
