| Steel reinforced concrete structure has many excellent properties, especially thegood ductility and energy dissipation performance in seismic area is broad space fordevelopment. In developed countries, this kind of structure has been widely used.Good bonding effect between two materials is to make sure that this kind ofcomponents in the two materials can work together. Want to make best use of theadvantage of this structure, we must make concrete and steel synergies within thecomponent to resist external effect. Cohesive action between steel and concretedirectly influenced the structure calculation assumption, the analysis and calculation ofdeformation and fracture theory.This article research is mainly carried out the following content:1) According to the existing research results, this paper expounds the relationshipbetween each part of the bond-slip, and with the help of experimental results at homeand abroad, the bond-slip constitutive relation, the affect factors are discussed insufficient theoretical analysis.2) Using ANSYS software, the steel reinforced concrete frame node finite elementmodel is established, using the nonlinear spring elements (Combination39) of concreteand steel interaction between the two materials are simulated. Using ANSYS softwareon the one-way load limit bearing capacity of steel reinforced concrete frame node onthe nonlinear finite element analysis, considering bond-slip of concrete and steel isestablished and does not consider the bond-slip both concrete and steel model, throughthe ANSYS simulation of the existing steel reinforced concrete frame node one-waystatic load experiment, the system summarizes the spring unit parameters Settings, modeling method, the finite element model and compared the results and experimentalresults verify the rationality of the ANSYS finite element model, using two modelsunder different strength of materials to study the ultimate bearing capacity of steelreinforced concrete frame node. |
