The Mechanical Properties Analysis Of Steel Reinforced Concrete Coupling Beams

With the accelerated pace of China’s reform and opening up, many complex high-rise buildings have emerged, steel reinforced concrete composite structure is widely used in such buildings, but also exposes the problem of imperfect research, relevant norms etc. This article will select will select steel reinforced concrete coupling beams of Such structures to study the mechanical properties, specific content includes the following aspects:1) Brief introduction of the research work that in order to solve the coupling beam shear overrun in recent years and revision of2010code on the coupling beam design.2). Research the mechanical properties of steel reinforced concrete coupling beams using finite element and contrast with ordinary concrete coupling beams, and analysis the shear of steel, reinforced to concrete using graph. Emphasizing the improvement of the mechanical properties of the coupling beam as well as the member stiffness and bearing capacity.3). On the basis of the above comparison, research the impact of cross-section parameters of coupling beam. These parameters include span-depth ratio, steel webs, steel flange and concrete strength. And to brief investigate the shear capacity formula of steel reinforced concrete coupling beams4). Take actual engineering of the framework core barrel structure for example, researching the difference of ordinary concrete coupling beams and steel reinforced concrete coupling beams, specifically compared the overall parameters and internal forces, and hoping that can provide some reference for future design.
