In order to popularize the application of external prestressing technique in existing building green retrofits,this paper presents the compilation of nonlinear analysis program for externally prestressed beams based on both the geometrical nonlinearity type and the material nonlinearity type. Combined the static-load-experiment with 12 concrete beams prestressed with external tendons, the calculative results showed that this program matched relatively well with the experimental results.
