- Description
- This
module
presents an overvi
ew of structural steel products that are used for steel bridge construction. It is intended to serve as
a reference and educational tool for structural engineers involved with bridge design and evaluation.
The primary focus is on
steel plate and rolled s
hape products that
are available under the ASTM A
709 Specification. This includes both a general
introduction to steel making practices and a detailed discussion of mechanical properties. It also includes a brief introduc
tion to
other steel products such
as bolts, castings, cables, and stainless steels that are often used for steel bridge connections and
components. References are provided to the relevant AASHTO and ASTM standards for additional information.
The mechanical properties of bridge steels ar
e presented based on the A 709 specification. The stress
-
strain behavior of the
various steel grades is presented to provide an understanding of strength and ductility. Fracture toughness is discussed to
relate
how the Charpy vee
-
notch test relates to fr
acture resistance in structures. Finally, the methodology for determining atmospheric
corrosion resistance
is presented along with the requirements for classification as "weathering steels" for use in un
-
coated
applications.
