Planar Asymmetric Cut H-type Frame-shear Wall Structure Layout Research

With the development of economy, a lot of buildings tend to be irregular in shape.Irregular building meets the requirements of the people for appearance, but itsstructural design add problems for designers.The first face is irregular structure’storsion problem under the horizontal loads,especially horizontal strong earthquakeloads.. Secondly,even if the structures satisfy the requirements of torsion, themembers resisting lateral force may not be reasonable. How to arrange the componentto resist lateral force, to control the torsion effect in the specified range, and themembers resisting lateral force reasonable is a difficult problem to the designer.This paper is mainly to study irregular planar H shaped building. The buildingis hospital ward of the Xiangya Hospital. The total building height is89.60meters,24layers,two layers are below the earth, and22layers are above the earth.. First wechoose the pure frame structure, the calculation results show that the lateral stiffnessof the structure,and the torsional stiffness can not meet the requirements. In theearthquake, the interlayer appears large displacement angle, displacement ratio alsoreached1.59, exceeding the standard requirement about1.5. In this case, we choosethe frame shear wall structure. The lateral stiffness of shear wall is far greater thanthe frame. At the same time, the ability of resisting lateral displacement will begreatly improved, but because of the large difference in stiffness, the arrangement ofshear wall will be easy to cause the eccentric of structure. How to arrange the shearwall, can meet the stiffness of lateral and torsional, and can also ensure the reasonablestress of the shear wall are the main research problems.Firstly established the PMCAD with PKPM software frame-shear wall model,the finite element software SATWE analysis, obtains the solution of the interlayerdisplacement Angle ratio, maximum displacement ratio, maximum displacement,cycle, each component of reinforcement to resist lateral force and a series ofvalues.On the research of the final plan in more detail, check the structure of shearweight ratio, just weight ratio, seismic shear coefficient,0.2Q0adjustment coefficientand a series of parameters is in line with the conditions, the problem of individual even Liang Chao reinforcement. Finally summed up the plane irregular h-type frame-shear wall structure of reasonable arrangement principles of shear wall, provideconstructive Suggestions for the same and similar projects.
