钢梁上托钢筋混凝土柱组合结构节点的有限元研究

1、ab atsteel beam and reinforced concrete column composite frame (rcs), composed of steel beam and reinforced concrete column, is a newly low cost and highly efficient structure for its economical utilization on the characteristic of steel and reinforced concrete. it is necessary and meaningful to kno

2、w the function of the joint, improve construction details of the kind of connections. it helps to assure the safety of the composite structures and widen the use of rcs composite structures through study on the mechanical behavior of the joint<the joint that reinforced concrete column supported b

3、y steel beam of steel beam and reinforced concrete column composite frame was studied in this paper.first, six joint models that reinforced concrete column supported by steel beam of steel beam and reinforced concrete column composite frame had been design in the pape匚 they were analyzed by the ansy

4、s 3-d nonlinear finite element program. in the analysis, the models were at the action of horizontal and vertical loading.distribution of stress in the core of the joint was researched. the load delivery mechanism of joints and situation of concrete borne load in the core of the joint were analyzed.

5、second, according to contrasting the simulating data of six models, we can obtain their features, reasonability and feasibility.the final, a number of issues to be resolved were made on the basis of the conclusion of the paper.keyword : steel beam and reinforced concrete column composite frame (rcs)
