- Abstract:
- With regard to a curved continuous bridge with box girder ， two supporting systems were respectivelydesigned，namely ，torsion-resist supports at all supports and torsion-resist supports only at both end supports ,single supports at all middle span supports，and comparative analysis has been conducted on their mechanicalproperties from moment，shear forces，torque and support reaction forces. Bearing eccentricity has been takeninto consideration in this paper，in order to investigate the mechanical properties of curved girder bridge withsingle supports at all middle spans further. Calculation results show that if applicable bearing eccentricity is setup， the disadvantages of curved girder bridge with single supports at all middle spans could be overcome，andits mechanical properties can still meet the requirements of engineering application.
