Introduction to AASHTO Bridge Design Specification

midasBridge TeamFebruary 20, 2024

1. Why do we need design codes?

   Numerous impressive structures were created before the formulation of standardized design codes, but challenges existed. The shift to modern design codes introduced a systematic and scientific approach to bridge engineering, enhancing safety, consistency, and reliability in design and construction. Design codes also play an important role in protecting bridge engineers by providing a framework for legal compliance, standardization, risk mitigation, and professional accountability.

Currently, Prestressed Concrete Beam Bridge, which is generally applied as the most economical bridge type for small and medium-sized bridges in construction works such as highways and national highways, has been introduced to the entire bridge construction field for almost 60 years after the technical proposal.


In this post, we will look at the initial development story and trends of the Prestressed Concrete girder.
