Program Main Features
This program calculates the response of bridge superstructures to dead loads, superimposed dead loads, post-tensioned loads, live loads, user-defined vertical loads, and temperature loads. The program creates some default load combinations; additional custom load combinations which can be defined by the user.
CIP RC/PT Girder also calculates individual girder and total width shear, moment and deflection, axial, support reactions (including live loads), displacements (deflections and rotations), and stresses at default points-of-interest (POI) or at user-specified POIs. CIP RC/PT Girdercan check the stresses (top and bottom of girders) and the ultimate strength of the section at various stages (i.e., Initial and Final,). This program can also check or design the shear capacity of the girders, analyze or determine the approximate level of post-tensioning force required to satisfy the stress requirements, and determine the amount of mild steel required for ultimate strength.
This product is specific to post-tensioned box girder and slab bridges, and may have a monolithic connection at the bent. Span hinges and a variety of column shapes and fixity conditions can also be accommodated.
General
- The design is performed according to the requirements of the Canadian Highway Bridge Design Code (CHBDC).
- Default working units are Metric (S.I.).
- Reduce input time using predefined libraries for CHBDC vehicle types, mild steel reinforcement, and post-tensioning tendons. You can modify or add data to each of the custom libraries. Select CHBDC design vehicle groups from the locked library loads or define a new design vehicle manually.
