Reinforced Concrete Beam Opening Behavior Research

The use of high-rise building in Beams with Large open, so that equipment from the beam pipe through the abdomen, can significantly reduce the building height and increase the use of an area of the building, can effectively reduce the cost and use of buildings and maintenance costs, and has a good comprehensive cost-effective. And the structure now used as compared to RC Beams with Large open with good mechanical properties, materials and the amount of the province and low construction cost, engineering practice has a broad application prospects.In this paper, reinforced concrete beam on the theoretical study on the constitutive relationship of reinforced concrete and the finite element model. The use of large-scale finite element software to establish a reinforced concrete beam hole and open hole prescribing finite element model, and through stress, deflection and strain analysis of the three parameters of the reinforced concrete beams of rectangular open-hole, the hole size and the level of location of the its impact on mechanical properties; reinforced concrete beam opening hole, the holes on the orifice size and location of the impact of stress and bearing capacity.
