Abstract:
The research purposes were that using the cellular steel-concrete composite beams to instead of steel shed support in coal roadway in this article, the typical honeycomb composite beam (hexagon hole and round hole) model was the fundamental research object, and the carrying capacity of the steel-concrete honeycomb composite beams was analyzed, and the change features of normal stress and shear stress which are on cross section of steel-concrete honeycomb composite beams after weakening web were analyzed by ANSYS. The results show that the mechanical behavior of steel-concrete honeycomb composite beams is superior to the honeycomb beam, and can play a good supporting role. The mechanical behavior of round hole of steel-concrete honeycomb composite beams is more close to the solid-web composite beams than the hexagonal hole of steel-concrete honeycomb composite beams, because of no angularity, the round hole greatly reduces the stress concentration phenomenon caused by the opening hole.
