Extended Evaluation of CBG (Curved Box Girder) and WCBG (Wide Curved Box Girder) Computer Programs
An extended evaluation of CBG and WCBG computer programs was conducted to study the inaccuracies of the CBG program as span/width ratios of curved rectangular box girders decreased. A total of 20 bridges were analyzed in this phase. The effects of abutment skew angle and degree of curve on important structural parameters was studied using the WCBG program. A total of 35 bridges were analyzed, for this portion. Results for the most part are presented in dimensionless ratios and indicate that analysis methods based on a unit beam concept are quite accurate for span/width ratios above two and degrees of curve below thirty. Results of the skew and curvature studies indicate that both cause significant changes in most structural parameters and dramatic changes in shear force and abutment reactions when compared with a straight bridge of the same span.
