| It bring different materials character and behavior and multiple structure's synthetic behavior after mixed reasonably and orderly into play. The design and calculation of join is one of the capital problems in structure's design and caleulation. Bceause the reliable and safe join is Premise of structure' s normal work. The hybrid hull core structure made up of steel coupling beam and the reinforced concrete shear wall is one kind of new hybrid hull core structure. And especially steel coupling beam have the big stiffness, the good performance, economy and so on. In the joint of steel 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 theoretical analysis to node of steel coupling beam and the shear wall, preliminarily discuss stress situation of core area, and propose the vertical bearing capacity and the level shear bearing capacity formula.(2) Based on the experiments of 1 specimens of steel-concrete composite coupling beam and the shear wall joints under low cyclic loadings and compare with the result before, analyze and discuss failure pattern of joint, the strain distribution rule, the vertical bearing capacity and the horizontal bearing capacity of joint, determined the point of yield and the node bearing capacity formula.(3) This text introduces briefly steel concrete hybrid structures characters, development history, fundamental type and analytic method of the text principles of nonlinear finite element method and related knowledge of ANSYS. Preliminarily analyze some specimen choosing modal and constitutive relation of material, make related parameter to study the joint bearing capacity. |
