Abstract:
The existed research shows that when SRC component is under stress, there is bond-slip happened between shape steel and concrete. And the bond-slip have a certain influence on the bearing capacity of SRC component, when component is loaded to ultimate load, the bearing capacity descends quickly because of the effect of bond-slip between shape steel and concrete. Finite method of fiber finite element is a useful way to simulate this kind of composite components, but it ignores the behavior of bond-slip between shape steel and concrete. So building a bond-slip formula for fiber element to simulate SRC component has a practical significance. It’s not only gets more precisely calculated results, but also make the simulation of failure model close to the practical situation. In this paper, in order to add bond-slip effect into fiber element theory, a formula was set up to adjust stress of steel material, which was based on constitutive equations of our bond-slip tests. The method was programmed in OpenSees and used to simulate tests of SRC frame under cycling load, the simulate results shows that the method suggested in this paper is an effective way to express behavior of bond-slip in SRC component.
