| Abstract | ||
| A layered technique formulation through the depth of reinforced concrete beam section is devoted to develop an incremental-iterative algorithm suitable for the analysis of beams strengthened by CFRP laminates under monotonic and cyclic loading conditions. Concrete nonlinear behavior in compression through loading, unloading, and reloading stages is considered with a tension-stiffening model to represent concrete in tension. A bilinear behavior with strain hardening model of steel reinforcement bars through loading, unloading, and reloading stages is used. A computer program Matlab code is developed and verified through comparisons with given experimental case studies available in literature, which show good agreement. Extending the present algorithm to include different sections, hybrid beams, and long term effects are recommended as future work. | ||
