Engineering for Structural Stability in Bridge Construction

Résumé du livre

This manual is intended to serve as a reference. It will provide technical information which will enable Manual users to perform the following activities: (1) Describe typical erection practices for girder bridge superstructures and recognize critical construction stages; (2) Discuss typical practices for evaluating structural stability of girder bridge superstructures during early stages of erection and throughout bridge construction; (3) Explain the basic concepts of stability and why it is important in bridge erection; (4) Explain common techniques for performing advanced stability analysis along with their advantages and limitations; (5) Describe how differing construction sequences effect superstructure stability; (6) Be able to select appropriate loads, load combinations, and load factors for use in analyzing superstructure components during construction; (7) Be able to analyze bridge members at various stages of erection; (8) Develop erection plans that are safe and economical, and know what information is required and should be a part of those plans; and (9) Describe the differences between local, member and global (system) stability.
