4. Conclusions The study proposes an evaluation formula for the flexural buckling strength of reinforced steel angle members, taking into account the effect of eccentric load and the amount of reinforcement. It is important to note that the proposed design formula is being tested through small-scale experiments to ensure its accuracy. These experiments are crucial in providing evidence to support the validity of the formula and, ultimately, its ability to deliver reliable results. By utilizing the quadratic function, it was able to effectively evaluate the inelastic behavior of the member while maintaining continuity between theories. This approach not only ensures accuracy but also enhances the overall reliability of our analysis. The test results confirm that the proposed formulas can evaluate the strength of eccentrically loaded members and reinforced steel angle members with acceptable accuracy.
