ANALYSIS OF SHEAR BEHAVIOR OF HEXAGON HOLE CELLULAR BEAM AND CELLULAR COMPOSITE BEAM

This article makes the research on the experimental and finite element analysis of the shear behavior of a hexagon hole cellular beam and a cellular composite beam under different parameters. Based on the experimental study, a non-linear finite element model is established on the basis of finite element software, ABAQUS. We carry out the analysis and comparison on the cellular beam and cellular composite beam of different opening rates, flange width and thickness. It was found that the shear resistance of a cellular beam and a cellular composite beam is related to their flange thickness, opening rates and connection degrees. The results show that: the flange thickness variation of a cellular beam has a greater effect on shear resistance, while the flange thickness variation of a cellular composite beam has a smaller effect on shear behavior; concrete slab improves the ultimate shear resistance of a cellular beam. Finally, we propose a calculation formula for the shearing force of a cellular beam and a cellular composite beam.
