Investigation On The Mechanics Property Of Epiboly Profiled Bar-Concrete Beam

The characteristic of Profiled Bat-Concrete structure is to set profiled bar in concrete. The profiled bar could be rolled or welded. The type of bar can be selected according to cross section area, performance of the member. The bar can enhance the bearing capacity and stiffness of the member, so that the cross section area of member can be significantly reduced, and function area of the building can be increased. The height of the room is increased .The height of the beam is decreased so that the net height of the room is increased, or the storey height and the total height of the building can be reduced .Because of highly improved strength and stiffness, Profiled Bat-Concrete structure can be applied to wide-span structure, heavily load structure and high rise building.Composite structure is widely applied due to its merits. Traditional Profiled Bat-Concrete structure is to set profiled bar in concrete ,while the paper proposed a new type of profiled bar concrete beam ,in which profiled bar envelopes concrete.The paper studied tests on three epiboly profiled bar concrete beams, bearing capacity of normal section, stiffness and behavior of cracks, and put forward formulas as advise .Based on extant nonlinear concrete theory, a FEM model was built by ANSYS program .The results of FEM analysis was verified by tests data .some parameters in FEM model were changed to build different models and the analysis results were compared with the advised formulas.
