Optimization Study On The Arrangement Of The High-rise Frame-Shear Wall In Henan

In the structural system of the high-rise building, the reinforced concrete frame shear wall structure system has been widely used in all kinds of buildings, because it can not only provide greater use of space, but also has good lateral resistant ability. In the structure system, the quantity of shear wall and shear wall layout is related to the safety and economic rationality of structure.In the actual structural design, the designer usually relys on experience to design.They adjust results of computer-simulation by the specification, what is time consuming and cconservative. That is so hard todevelop the effective understanding foe the frame-sheer wall structure. Because the traditional structural design is too conservative, the frame-sheer wall structure optimization design is so necessary. At present, the specification on high-rise building structure selection and reasonable arrangement has not yet developed specific provisions. Based on the principle of conceptual design, we study and analyze the safety and reliability of the frame-sheer wall structure to enhance the ones of buildings.Firstly, this paper introduces the principle of the frame-shear wall structure space cooperative work, and analyzes the layout of the frame-shear wall structure. Then,based on the construction scheme, four different shear wall arrangement models are selected to be simulated by the software PKPM and it use YJK sofeware to cheeck the data. Besides,all the models satilfy the rules of structureral design and specification.Finally, through the comparison of various model structure of the shear weight ratio,stiffness to weight ratio and period ratio, elastic ratio, elastic inter story displacement parameters, we judged the model of shear wall arrangement rationality, and choosed the most appropriate arrangement of shear wall model. The optimal shear wall arrangement scheme and the original design scheme are compared and analyzed to which show that the shear wall arrangement is safe and economical. The analysis results show the reasonable quatites and arrangement of the shear-wall. Besides, we can provide some reasonable suggestions for the application of the frame shear wall structure in practical engineering.
