Steel Beams Embedded In The Experimental Research And Analysis Of The Length Of The Bearing Capacity Of Steel - Concrete Composite Coupling Beams And Concrete Shear Wall Node

The steel-concrete composite structure apply more and more in the domestic and foreign civil engineering, and there are many prominent merits such as the high bearing capacity, the light own weight, frugal material, the small cross section dimension and the high aseismatic performance and so on. The hybrid hull core structure with the steel-concrete composite coupling beam is a new construction structure, and it is advantageous in further enhancing our country composite structure research level, and expanding and accelerating the steel - concrete composite structure application. In the joint of steel - concrete composite coupling beam and the shear wall research, analysis the failure pattern, bearing capacity of core area and some influence factor about bearing capacity—those have the important value for instruction design, promoted the hybrid hull core structure consisted by combination beam and shear wall and the correlation regulations formulation. At this point, the paper mainly does work as follows:(1) According to the steel-concrete composite coupling beam and the shear wall joint theoretical analysis, preliminarily discuss stress situation of core area, and propose the vertical bearing capacity and the level shear bearing capacity formula, and analyze its influence factor.(2) Test 2 steel-concrete composite coupling beam and the shear wall joints specimens under low cyclic loadings. Analyze and discuss failure pattern of joint, the strain distribution rule, the vertical bearing capacity and the horizontal shear bearing capacity of joint, and propose the influence of steel girder embedment length of composite coupling beam to the bearing capacity of joint.(3) Preliminarily analyze some specimen structure measure to joint bearing capacity influence. In terms of the finite element elasticity analysis to specimen, understand steel girder stress distribution situation, and favor in the experiment.
