Ultimate strength of composite beam with web openings subjected to combined interaction of negative bending and axial tension

Abstract

This research studies had the hypothesis that axial tension presents on the steel section with web openings of the steel-concrete composite beam may accelerate the failure state of composite beam. The developed analytical models in the previous research studies in the composite beam with web openings have evaded the presences of axial tension. In order to verify this hypothesis, a nonlinear three dimensional finite element model (FEM) was developed for composite beam subjected to combined negative bending and axial tension. The model was validated with available experimental data, and the axial tensile load, vertical load and failure mode at ultimate limit state were reasonably fit well with the results of experiment. A parametric study on the square web opening with various widths in square openings was then carried out with validated finite element model. The results show that the early failure state exists in the composite beam with web openings steel components subjected to negative bending and axial tension. This failure prediction should be considered in designing process of the composite beams located where axial tension presents. The results can serve for further study on the developing design models of composite beam with web openings subjected to negative bending and axial tension.
