Synopsis
Excerpt from The Schwedler Bridge
At about the same time appeared a kind of bridge on the Continent, the shape of which is exactly the opposite of that which theory would indicate as the proper form. The top flange is horizontal, the under one in the form of an arch, as shown in Fig. 3. These were constructed without any abutments capable of resisting horizontal thrust, and cannot be considered as arches.
