The Dynamic Analysis And Seismic Discussion Of The Shear-Wall Structure With Src Supporting Frames And Girder Transfer Floor

with the city urbanization, land costs rising, and the high-rise buildings increasing,many tall buildings of the city commercial district often require the buildings largerspace used as restaurants, shopping malls, and the upper part is often used as offices orresidences. Due to the different functional requirements, these buildings offen need toconvert structural style. When the upper is the shear wall structure, and the lower frameis supported by frame pillar, the upper load is transferde to the lower frame pillar by thetransfer beam, this conversion form is called frame supported conversion. Because thegirder transfer layer has been used widely due to the force transmission direct, clear, andeasy to calculate,so this paper pays attention to analysy the trailing wall girder transferfloor frame supported shear wall structure.The frame pillar and beam supported frame of the Girder Transfer floor Shear-WallStructure with Supporting Frames at the bottom will generally use reinforced concretematerial, but their strength is lower, the load of the upper part of the shear wall willcause frame pillar and beam supported frame of the bottom to become biger to impactarchitectural function, and their ductility, aseismic weak ability is poor. For the steelreinforced concrete member with higher bearing strength, better ductility and aseismiccapability, the steel reinforced concrete is introduced into the beam supported frameand frame pillar, which can improve the seismic performance of the overall structureIn this paper a analytical model is firstly created. Select rightly the section of RCbeam supported frame, RC frame pillar, and the section and the steel Specification sizesof SRC beam supported frame, SRC frame pillar by the PKPM calculation results. Bycomparing it can apparently find the section size of SRC beam supported frame andSRC frame pillar become smaller. At the same time, analyse their influences onstructural seismic indexes for section variation, and explor the change of the upper shearwall force transmission route of shear wall on the transfer beam and its sectionmechanical characters for the section height becoming higher. Then establish3modesof steel content and section changes of the beam supported frame, frame pillar. UseETABS to explore the periodic change, vibration characteristics of the three modes. Bycomparing the results it reveals the effect of structure for section and steel quantitychanging.Then considering the7degree multiple earthquake response spectrum of theX, Y unidirectional earthquake action, use mode decomposition response spectrum method to analys of the structure’s bending moment, the shear,layer lateraldisplacement and angle of floor displacement characteristics to find the regulations.Comparing the analysis results of the three mode, it reveales frame-supported beam andframe pillar seismic characteristics differences for section and steel content. At the sametime some conclusion will be given by contrasting the results for periodic structure,floor displacement, storey shear between PKPM and ETABS. Finally, use the elastictime-history analysis to explor envelope curve characteristics of floor shear anddisplacement in three modes acted by X, Y unidirectional seismic wave, compare theresults with the standard response spectrum method to analyse diffent seismic wave’seffection. Lastly explore the vertex displacement and the bottom frame pillar seismicshear response of specific mode in different seismic waves.
