Warren Bridge Force Diagram. The first was a wood and iron rectangular truss by a. These forces are represented in the free body.
Warren pratt howe k truss c. Because the bridge has two parallel trusses it is herein assumed that the total load applied on the bridge is divided equally to each truss. Here are two diagrams showing how the forces are spread out when the warren truss is under a load.
A fbd can be constructed in three simple steps.
Warren trusses are normally used for spans up to 61 m in length. The first shows a localized load in the center of the bridge. This is the washington ave. Beams and columns deflection and stress moment of inertia section modulus and technical information of beams and columns.
