Reinforcement Design Of Shear Walls With Complex Cross Sections Of High-rise Buildings

House building of our country has advanced rapidly in all fields. At the same time, high-rise buildings whose heights grow fastly, layers increased highly, areas expanded unceasingly have appeared one after another and numerous shear walls with complex cross sections have come into being. Shear walls with flanges are shear walls with complex cross sections. And the section shapes are mostly 1 shaped section, T shaped section, I section and irregular groove profile shaped section. At the moment, calculation of bearing capacity and basic concepts for shear walls with complex sections are not clearly defined in the standards from different countries. Engineers usually refer to the reinforcement design method for the shear walls with simple cross sections in face of performing design for complex shear walls. In this thesis, ETABS and PKPM are used to achive structural elastic analysis. Then one of the reinforcement design method from partitoned shear wall reinforcement design moethod, combimed shear wall reinforcement design method, whole section shear wall reinforcement design method according to the result of analysis.The details of studying are as follows:(1) The related calculation theories about normal section bearing capacity and reinforcement design method of structural members with complex cross sections at home or abroad, including the methods of quivalent-column and section block on special-shaped columns, the reinforcement design method on combimed shear wall and whole section shear wall, were discussed.(2) Probed the wall element model combined with PKPM/SATWE and ETABS range from its basic assumption to engineering applicability. It is shown that, the wall element model of SATWE can reflect the force state veritably and plate girder wall unit model of ETABS tend to be influnced easily by the opening of shear wall.(3) Builded a model of frame-core wall structure by PMCAD and ETABS. Showed the validity of the model according to JGJ 3-2010 and GB 50011-2010. The structural analysis shows that the control parameters of the model satisfy the demand of the standards.and the structure is capable of wind-resistant and earthquake-resistant.(4) Researched the interforce caculation method, reinforcement caculation method and design flow and proceed the reinforcement design and compared the sesults.It is shown that, partitoned shear wall and combimed shear wall reinforcement design method have security problems or negative economics and whole section shear wall reinforcement design method is more reasonable.
