Abstract
To cross deep valley PC box girders have been adopted. Recently, a developed form of the girders with corrugated web begins to be used to satisfy the severe request of the reduction for the cost and time during construction. However, the corrugated web does not possess rigidity along the span axis, and influence due to shear deformation strongly appears under bending. This report introduces an elastic equation extending beam-bending theory considering shear deformation. To respond to the demand from bridge engineers who require rational design method, a series of analyses varying structural dimensions were achieved and the effect of the shear deformation is investigated for the actual structure.
