Analysis On The Mechanical Behaviors Of Beam-tape Transfer Floor And Related Component In Frame-supported Shear Wall Structure

Frame-supported shear wall structure which has good structural arrangement, good to meet the requirements of architectural functions, meet the needs of social development, So transfer storey structure become one of the most rapid development structure forms in recent years. But because the complexity of the structure, its transfer component stress performance and structure stability has been the the main existing problems structure design, And many aspects about the theoretical research is not sufficient, The mechanical behaviors and deformation characteristics in weak parts of transfer storey also need further study.This article will focus on transfer storey structure, using SATWE module and the large-scale finite element analysis software ANSYS in overall and partial component analysis to structure. The main research contents and conclusions are listed as follows:1. By changing the transfer storey vertical position, using SATWE software to make overall analysis, compare the natural period of vibration, seismic response, maximum shear force of floor, the maximum displacement angle and other physical quantities, to find out their common points and different points, the results showed that, regardless of high or low conversion, the transfer storey will appear larger seismic response, and it will forms a weak storey easily at this position. Secondly, with transfer storey increases, the seismic response has exacerbated, And it is not conducive to seismic.2. By large analysis software ANSYS to make analysis in deformation, cracks and other aspects to different forms of transfer storey structure,which are at the action of vertical load stress. The results showed that, the transfer beam with shear wall structure, due to the conversion of transfer beam and the upper wall to form an organic whole structure, So it has the best performance in the bending deformation, followed by transfer structure which has hole in the shear wall, the transfer structure which supports column is worst in the bending deformation. In addition, make an analysis in stress, crack and deformation for a transfer structure which has secondary beam, the results show that the transfer beam with the secondary beam is complex in stress distribution, crack appeared in the bottom of the beam and at the side of no secondary beam. deformation diagram display transfer beam has obvious torsion.3. By changing the reinforcement ratio of transfer beam, concrete strength grade, high span ratio of transfer beam.To compare the structural bearing capacity and deformation capacity in every situation. Get some conclusions as follows:(1) with the reinforcement ratio increases, the structure bearing capacity rises somewhat, but range is not big, but the structural ductility decreased obviously. It is not recommended to substantially increase the reinforcement ratio to increase bearing capacity;(2) with the increase of concrete strength, the structure bearing capacity are also rise, so as to the reinforcement ratio, the deformation of the structure is greatly reduced.(3)with the high span ratio decreases, the ultimate bearing capacity of structure has greatly enhance.at the same time, there was no significant drop in deformation. The results show that, the reasonable ratio of height to span helps to ensure bearing capacity and improve the deformation of the structure.
