Nonlinear analysis of RC frame structure including bond-slip effects

The RC structure under monotonic loading was analyzed including bond-slip effects based on fiber model,flexibility method.Consideration of bond-slip between concrete and bar,the corner and curvature of the components were calculated.During the course of iterative,the curvature were used to amendment the one of section.At last,the load-displacement curves were gained.By comparison between the results considered the slippage and ones not considered the slippage,as well as comparison between results of computation and results of tests:The results could reflect the bond damage between steel and concrete.
