Trusses
When relatively long spans are involved, trusses are frequently selected for the floor-framing system. As for open-web joists, mechanical ductwork can […]

The following shapes for truss members are typically considered: H sections, made with two side segments (composed of angles or
At every joint in a truss, working lines of the intersecting members preferably should meet at a point to avoid eccentric
When it is necessary to locate a truss bridge on a curve, designers should give special consideration to truss spacing, location
Principal parts of a highway truss bridge are indicated in Fig. 13.1; those of a railroad truss are shown in Fig.
Truss members generally are designed to carry only axial forces. At panel points, where members intersect, it is desirable that
The following sequence may serve as a guide to the design of truss bridges: Select span and general proportions of
For long or heavily loaded bridge spans, restrictions on depth of structural system imposed by vertical clearances under a bridge generally
An arch is a beam curved in the plane of the loads to a radius that is very large relative
