The topic of the paper is to investigate procedure to determine bending moment resistance of girders with corrugated webs. Concepts provided by Eurocode EN 1993-1-5 and EN 1999-1-1 are different and not very clear for practical design. To clarify determination of elastic critical bending moment, a finite element model of simply supported beam under uniform bending moment has been created. Positive influence of web corrugation on bending stiffness has been expressed through the improved factor c1 used for flat girders. Results of bending moment resistance have been compared to show the difference between the concepts and to provide more appropriate assessment.
deformations were obtained by using the response modification factor R (for the seismic forces), and the deflection amplification factorC d . The values of R and C d for existing and retrofitted structures are presented in Table I . Table I: Response
cement-treated considering element size is adjusted by the introduction of compression softening factorC ( Fig. 9 ) base on the test results. C is a post-peak adjustment factor for the stress-strain relationship. The adjustment factor depends on L
