The Design Application of Steel Fiber Concrete on Bottom Frame Structure

Abstract:

The concrete frame with bottom frame structure bear the load from the upper floors, roofing and brick walls, internal force is quite large, so the designed section size of frame beams is big, sometimes even the clear height of the building can't meet the architectural requirements; And more reinforcement, construction of concrete are difficult to pound, even vibration bar are difficult to insert into the beam, seriously influence the construction quality of reinforced concrete and the frame structure quality can't t be assured. This article introduces the design and application of steel fiber reinforced concrete in the bottom frame through the practical engineering examples. Steel fiber concrete can enhance the tensile and shear strength, and make it has good resistance to crack and toughness. As a result of the steel fiber concrete, the bearing capacity of bottom frame is greatly improved, and the problem in the project is solved.
