The Seismic Optimization Of Emulsion Comprehensive Building In Liaoning Province

The wall of frame structure generally adopt infilled wall, non load bearing only to surround and separate, generally assembled with the light plate materials such as masonry. In the actual engineering design, the infilled wall generally equivalent to beam line load, consider the influence of infilled wall on the structural stiffness by the cycle reduction coefficient. This approach doesn’t consider the actual effect of infill walls, ignoring the effect of filler wall on the whole and local structure.The optimizing design of structure is the development trend of engineering design recently. It makes the design of structure to develop more reasonable and safer. As the industrialization of society and the development of science and technology, for frame structure is not only durable 、 economical and reasonable, but also to meet different needs in different situations.The traditional structural design according to the past design experience,constantly test and adjust to meet the requirements of specification and the overall design ideas is single,So it’s necessary to have Study on the optimizing design of structure.This paper optimized and analyzed reinforced concrete frame structure in the horizontal earthquake effect.The main job is to:Using the PKPM software to calculate and analysis the structure,to meet the requirements of specification,using ANSYS software to optimize the design of the reinforced concrete frame structure based on it.Under the action of earthquake, seeing the height of filler wall、the section size of columns and beams as the design variables, and purse the purpose of total cost of reinforced concrete to analysis reinforced concrete flame structure with the software ANSYS, getting finally section size after the optimization.In the optimization process,do the static,modal and spectral analysis,extract the internal force,deformation of structure,compare frequency and vibration type of different models,verify the cycle reduction coefficient of infilled wall to the main structure.This paper establish the finite element model of frame structure according to engineer example,then do the seismic performance optimization design. And the finite element model is completely in conformity with “Code for seismic design of buildings”(GB50011-2010)and“The design code of reinforced concrete structures”(GB50010-2010).By comparing the optimization results of the correlation,steel consumption decreased by 15.5 percent,Concrete consumption decreased by 13.8percent, project cost decreased by 14.4 percent, the unit cost of reinforced concrete reduced by 0.8 percent after optimization,founding that the results meet the requirements of the target and better meets the actual engineering.
