Interactive Software for Analysis and Design of GFRP Reinforced Concrete Columns per ACI 440.11-22 Code

As structural engineers become more familiar with the new ACI 440.11-22 code, it is inevitable to develop software for structural design of reinforced concrete with GFRP bars. In this paper, the development of a comprehensive interactive software for designing and analyzing circular and rectangular concrete columns reinforced with GFRP bars is presented. The program can analyze column sections subjected to biaxial bending and axial compression/tension. The software is extensively tested against an independent program developed for validation. Comparisons with experimental results are carried out. Two examples are solved highlighting similarities and differences in behavior with columns reinforced by conventional steel bars.
