| This dissertation presents a static and dynamic analysis of curved thin-walled girder bridges using a new direct stiffness method. This method is based on the warping torsion theory of curved thin-walled girders. Seven degrees of freedom at each joint are taken in this procedure: displacement of shear center in the direction normal to the plane of curvature, displacement of shear center in the direction vertical to the plane of curvature, axial displacement, angular displacement due to bending moment M... |
