Bond-Slip Effect in Analysis of RC Beams Using Layered Section Method
- 발행 : 2005.11.01
초록
An analytical procedure to analyze reinforced concrete (RC) frame subject to cyclic as well as monotonic loadings is proposed on the basis of the layered section method. In contrast to the classical nonlinear approaches adopting the perfect bond assumption, the bond-slip effect along the reinforcing bar is quantified with the force equilibrium and compatibility condition at the post-cracking stage and its contribution is implemented into the reinforcing. The advantage of the proposed analytical procedure, therefore, will be on the consideration of the bond-slip effect while using the classical layered section method without additional consideration such as taking the double nodes. Through correlation studies between experimental data and analytical results, it is verified that the proposed analytical procedure can effectively simulate the cracking behavior of RC beams, columns and Frame accompanying the stiffness degradation caused by the bond-slip.
