Study On The Strength Of Normal Section And Diagonal Section Of Reinforced Concrete Shear Wall

The RC shear wall is belong to a member under an eccentric axial force, should calcuate the strength of normal-section and diagonal-section. However, the two aspect strength calulation are problems that haven't been solved very well. In this paper, in order to solve the problems exist in the current code, a study of the shear wall strength calulation have been given based on the current flexural and shear strength researches. The mian contents are as follows:(1) Study the bending property of normal section and shear property of diagonal section for shear wall according to widely collecting the experimental data of flexural and shear strength of shear wall, and analyse the influence of main influencing factors on bearing capacity.(2) Based on the shear property experimental data of shear wall, the calulation formulas of shear strength of reinforced concrete shear wall obtained expressed with different concrete strength indexes adopting mathematical statistics method, and check the calulation by the example analyzing.(3) Based on the experimental data of high strength concrete flexural shear wall, a practical bending bearing capacity formula of high strength concrete shear wall is put forward, and shows the feasibility of it through comparing the results to experiments data. Then adopt Design Code of Concrete Structure and Technical Specification for Concrete Structures of Tall Building for calulation for collected data, and comparative study on experiment results.
