A rigid-frame
bridge is a load resistant skeleton constructed with straight or curved
members. It is a simple structure with top and sides of one solid piece of
reinforced concrete. It is specially
designed to resist bending, shearing, and axis loads. This type of bridge was
cheaper to construct and easy to maintain and stronger than traditional bridges
for its day. Wilbur Wilson, a professor
of Civil Engineering and researcher of the fatigue of structures at the
University of Illinois was a tremendous advocate of this type of structure.
