Two-Hinged Arches
A two-hinged arch has hinges only at the supports (Fig. 4.2a). Such an arch is statically indeterminate. Determination of the […]
Structural Analysis
Truss Supports and Other Details
End bearings transmit the reactions from trusses to substructure elements, such as abutments or piers. Unless trusses are supported on
Trusses
When relatively long spans are involved, trusses are frequently selected for the floor-framing system. As for open-web joists, mechanical ductwork can
Truss Member Details
The following shapes for truss members are typically considered: H sections, made with two side segments (composed of angles or
Truss Joint Design Procedure
At every joint in a truss, working lines of the intersecting members preferably should meet at a point to avoid eccentric
Truss Bridges on Curves
When it is necessary to locate a truss bridge on a curve, designers should give special consideration to truss spacing, location
Truss Components
Principal parts of a highway truss bridge are indicated in Fig. 13.1; those of a railroad truss are shown in Fig.
Truss Connections
Truss members generally are designed to carry only axial forces. At panel points, where members intersect, it is desirable that
Truss Design Procedure
The following sequence may serve as a guide to the design of truss bridges: Select span and general proportions of
