Pressure steel - concrete composite floor high-rise buildings in China 's multi- applications become increasingly widespread. It can make full use of steel the tensile and concrete compressive characteristics , to show its superiority in force performance indicators . Combination floor by steel and concrete interface shear connectors measures to ensure the maximum carrying capacity of the board to be fully tapped , the connection can be divided into full shear connection and partial shear connection failure modes were bending failure and vertical shear cut bond failure . Current specification , combination floor design , there is no clearly defined. For a different type of board , longitudinal shear bond bearing capacity of composite slabs , required by test data regression , m-k method commonly used at home and abroad . The combination plate flexural capacity of ordinary reinforced concrete plate bending principle -sectional plastic flexural loading theory , a reduction factor of 0.8 . The stiffness can FLOORS conversion method in accordance with the cross-section of ordinary reinforced concrete floor , but did not consider the impact of the slip on the stiffness of the composite floor slab . To investigate the steel sheeting with indentation - CONCRETE FLOORS force and the deformation properties of the theory and practice in contrast , combined static loading tests Baoye 8 U76 6 U51 combination floor , according to the test results , its longitudinal shear capacity of composite floor slab normal section flexural capacity and deflection study . In addition, this article also affect the the combination floor of factors , such as : stud , transverse reinforcement , concrete models , pressure plate thickness , these parameters combination floor bearing capacity of , and provide reference for the design of combination floor .
