An analytical study on two-plate-girders skew bridges
Reported in this paper were the analytical calculation of the additional bending stress occurring to slabs and the study of the measures to reduce the stress, on a sample bridge having a skew angle of 60 degrees, a radius of curvature of 800 m and main girders forming angles at intermediate supports with those of adjacent spans (the application of the rationally-designed bridge to such a bridge is not allowed presently). As a result, it was confirmed that no stress problem was involved even when the bridge of the studied structure was designed in the same procedure as conventional plate girder bridges and that no concrete reinforcement of cross beams and no laterals ware required specifically. In the case of a rationally-designed bridge having a skew angle at bridge ends or a smaller radius of curvature, however, it is possible that exceed stress resultant occurs near intermediate supports. Thus, further data accumulation through studies is required.
