Research On The Optimal Design Of High-rise Residential Shear Wall Structure Based On Seismic Performance

China's economic and technology is in a stage of rapid development, with the continuous progress of urbanization, high rise buildings emerge in endlessly,Especially high-rise residential has become a trend,As one of the main structural forms of high-rise buildings, the shear wall structure has been widely used in the field of modern high-rise residential buildings, Because the high-rise shear wall structure is high, the construction period is long, so the cost of capital investment is also more,And it need the high requirements of seismic performance, so most of the architects in the design of high the rise buildings take a relatively conservative design principles, in order to ensure the safety of the structure or in order to save time to catch the progress of projects and some other reasons, only after the pursuit of various indicators to meet the requirements of the relevant norms, with the previous design experience to meet the structural safety requirements, and not on the shear wall structure of a thorough in-depth analysis. This leads to excessive shear arrangement,over-big stiffness, Structures of the lateral shift though small, but the structure to absorb seismic forces will be larger, so it results unsafe design and material properties underutilized. But also to improve the cost structure of the project, so the rational arrangement of shear wall and optimizing the design of shear wall structure are of great significance.After studying the theory of shear wall structure and optimal design, this paper carried out the following main content:(1) Taking a high-rise residential shear wall structure of Xingyang as the research object to make the numerical simulation. With its structural construction Pictured basis,and meeting regulatory requirements, based on the model of the original structure of some of the structural arrangement optimization, mainly for the shear number and length of the pier, to give the other two model programs, and then use high-rise building structural finite element analysis software program ETABS and PKPM the three models modeling, analysis and calculation.(2) Through two kinds of software respectively using mode decomposition response spectrum method to analyze and calculate the engineering examples, get the structure of the seismic performance data, structural self vibration cycle,interlayer displacement angle, story shear force and bending moment, stiffness ratio,through comparative analysis of three schemes above the parameter is known, the optimized scheme also meets the specification requirements, periodic change, inter story displacement angle increases generally, and reduce the internal force of the structure, indicates that the structural stiffness decreases, material make full use of,seismic performance is improved and save the cost of a certain(3) The two software of ETABS and SATWE analysis results were compared and analyzed, and points out their similarities and differences. It is found that the error exists between the two, but were within the allowable range, so you can use SATWE analysis results to verify the correctness and rationality of ETABS software.In the optimization design of the structure, combined with the results of the analysis of the two kinds of software, summarizes some relevant rules and finding out the key control factors, provide some reasonable suggestions of reference for some similar structural engineering optimization design.(4) Finally, add up the amount of material of Option One and Option Three,and the comparison shows that the reduction of the number of the shear wall and the reduction of the wall limb length makes the structural cost savings of 4.9%, the economy has been significantly improved.
