Application And Analysis Of High Shear Wall Structures With Dual Coupling Beams In High Rise-residential

The form of sheer wall structure is generally used in the building structure of high-rise residence,but it often encounter the overreinforced phenomenon which results from the lack of coupling beam‘s shear capacity.Because most of structure designers are not very familiar with the performance of dual coupling beam component and its specific effect on the overall structure,so the dual coupling beams can not be widely used in actual engineering structure design.This paper attempts to analyze double coupling beam‘s overall influence on the shear wall structure in ordinary high-rise residence,and try to find the design parameters which are most favorable to the overall performance of the structure by controlling the variables.Making a contrastive analysis between single coupling beam and dual coupling beams through the SATWE finite element structural analysis software.It is proved that the double coupling beam structure has a great advantage in reducing the seismic shear force and solving the problem of the coupling beam‘s overreinforced phenomenon.Meanwhile,it is proved that the dual coupling beam component presents better ductility in the structural earthquake-resistant through some index,such as shear span ratio.And the static elastic-plastic analysis of PUSH-OVER also confirms that the design method of double coupling beam is better for the ductility of the whole structure,and it can avoid the plastic hinge to come into being prematurely in vertical members(shear wall).At the same time,in order to find the most favorable design method,this paper compares the ratio of the upper beam and the under beam‘s height,the size of dual coupling beam‘s centre joint,the span-depth ratio of dual coupling beam in different coupling beamand combined engineering‘s actual operability with theory to establish three contrast models.It can be seen from the data that the size of the coupling beam‘s centre joint has no obvious effect on the overall performance of the structure,but it provides the structure designer more choice,so they can adjust the the height of the the upper beam and the under beam ob the basis of actual needs.The requirement of stress heremainly refers to the vertical loadwhich directly contact the upper and under beam.According to the previous study,the distribution of the force in the double coupling beam is positively correlated with size of coupling beams.The size of coupling beam‘s centre joint also has no obvious impact on the holistic performance index of structure.We can decide the size of the centre joint according to the construction complexity during the design process,and I suggest that it should be no less than 50 mm.By comparing some of the model data of the span-depth ratio,it is found that the double coupling beam and single coupling beam are both sensitive to the difference of span-depth ratio.This paper combined the theoretical analysis with the finite element numerical simulation of SATWE software to analyze the various uncertain parameters encountered in the design of dual coupling beam component.The multi-model comparison analysis demonstrates that the double coupling beam has a great advantage in the application of shear wall structure of high-rise residence and to find the the parameters which will influence the overall structure.To promote the use of double coupling beam in structural design and provide some reference advice for structural designers in the use of dual coupling beam.
