Analysis On The Mechanical Behaviors Of Reinforced Concrete Deep Coupling Beam

Reinforced concrete shear wall structure is the most widely used structure in high-rise building at present,the beam plays an important role in shear wall structure,there are all kinds of coupling beams is an important component of energy coupled shear wall in high-rise building structures,the beam is the first line of seismic fortification. When the lateral deformation of the structure is larger,as Stiffness of wall is not easy to meet, reduce the coupling beam is a way to improve the overall stiffness of the structure, in addition to the reasons for the building structure, the coupling beam has become a common component in high-rise building.Research shows that the coupling beam stress with the general characteristics of Liang Mingxian, according to the traditional reinforcement method is difficult to meet with the beams bearing capacity, ductility and energy dissipation performance requirements, so to find a suitable coupling beam reinforcement of reinforced concrete structure design important significance.The design and analysis software Midas/Building is used to analyze the elastic response spectrum of a 25 story shear wall structure, the average span beam structure change, effect of high ratio on the seismic performance of beam cross shear wall structure of the. the results show: coupling beam structure has good performance in resisting earthquake, can better ensure the lateral stiffness of the structure. Then established the span ratio of five different reinforcement schemes for shear wall coupling beams model 1 using the finite element software ABAQUS, nonlinear analysis is carried out, study on the mechanical properties of different reinforcement schemes, and focus on the study of the effects of concrete strength grade and different reinforcement ratio on the mechanical properties of the two schemes are studied, the conclusions and recommendations of the study can be used as reference for designers.
