In designing statically indeterminate structures of partially prestressed concrete under service load conditions, it is reasonable to take into account the reduction of flexural rigidity due to cracking for computing redundant forces.
In this paper, experiments are conducted to clarify flexural deformation of partially prestressed concrete beams, and a simplified moment-curvature relationship is proposed for rapid nonlinear analysis of continuous girder bridges.
Furthermore numerical examples clarify effects of the level of prestressing and the pattern of cracking on redundant forces under service load conditions.
