| 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) Applying Finite Element linear Method to Analysis of the node's steel beam and to guild the test of node.(2) 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 bearing capacity and formula, and analyze its influence factor.(3) Test 5 steel-concrete composite coupling beam and the shear wall joints specimens under low cyclic loadings..Analysis of failure mechanism and the primary factors which affected the bearing capacity of joints.(4)The failure process and failure characteristics of the joint are given by the analysis of the five specimens failure mechanism summarized.(5) SPSS software is used to make analysis of the main influencing factors of the bearing capacity of joints from the experiment the corresponding regress formula are also presented in the paper and the accuracy and safety is verified by the more data. |
