Girder-PC - A Computer Program for Design Checking of Prestressed Concrete Box Girder Bridges.

摘要

A computer program for the design analysis of multi-span prestressed concrete bridge structures is described,the analysis and design checking procedures are explained,and a detailed user's guide is presented. The program is primarily applicable to cast in-situ prestressed concrete box girder bridges. The girder must be straight in plan,and it must be possible to idealize any girder cross section as an equivalent I-section,otherwise the program is applicable to structures of a wide variety of geometrical shapes. The girder depth,width and slab thicknesses may vary arbitrarily along its length,vertical or inclined monolithic piers may be specified,and internal hinges and expansion joints may be included. Any number of prestressing cables may be specified,with arbitrary profiles and anchorages at any point. Some spans of the girder may be non-prestressed if desired.
