PCI eLearning Course T523: Girder Stability During Transport-Proposed Recommended Practice Errata v2.2

Proposed Recommended Practice Errata v2.2

Pdf Summary

The proposed errata consists of various changes and additions to the Recommended Practice for Lateral Stability of Precast, Prestressed Concrete Bridge Girders. Some of the key changes include:<br /><br />- Replacing the first bullet in the second paragraph of section 3.2.2 with a new bullet regarding the factor of safety against cracking.<br />- Adding a paragraph after the second paragraph of section 3.2.2 to address cases where the maximum factor of safety occurs just before cracking.<br />- Adding a sentence to the last paragraph of section 3.2.3 to emphasize checking both sides of the girder for critical stresses and factors of safety.<br />- Modifying equations in sections 3.2.3.1 and 3.2.3.2 to reflect changes in factors of safety.<br />- Adding a paragraph at the end of section 3.2.3.2 to discuss the possibility of the girder rotating past vertical due to wind decreasing rotation.<br />- Revising the second paragraph of section 3.3.1 to provide a clearer explanation of the three different checks performed to verify girder stability.<br />- Making revisions to various equations and definitions in sections 3.3.2, 3.5, 4.2.2, and other sections.<br />- Adding equations and notations related to wind, deflection, and other factors.<br />- Making corrections to equations and terms used in various sections.<br /><br />These proposed changes aim to improve the accuracy and clarity of the recommended practice for lateral stability of precast, prestressed concrete bridge girders.
