Research of Prestressed Concrete Hollow Multi-Ribbed Composite Box Girder
Base the shortcomings of pre-simple-supported post-continuous girder bridge construction, a new beam-bridge convert structure system is proposed, that is a kind of structure form of prestressed concrete hollow multi-ribbed composite box girders, the calculation method of two phase and noting are put forward. the kind of Cast-in-place assembly structure is light self-weight, force structure reasonable, easy construction, overall good and overall cost low.
