ISO 21725-1:2021 Scope
This document provides information to perform the design of the prestressed concrete I-girder bridge for road that complies with the limitations established in 6.1. The rules of design set forth in this document are simplifications of more elaborate requirements.
Designs and details for new road bridges address structural integrity by considering the following:
— the use of continuity and redundancy to provide one or more alternate paths;
— structural members and bearing seat widths that are resistant to damage or instability; and
— external protection systems to minimize the effects of reasonably conceived severe loads.
