Types of Structural Members and Supports
Structural members are usually classified according to the principal stresses induced by loads that the members are intended to support. Axial-force […]

Figure 13.3 shows some of the common trusses used for bridges. Pratt trusses have diagonals sloping downward toward the center and
Loads are forces that act or may act on a structure. For the purpose of predicting the resulting behavior of
In the most natural type of arch, the horizontal component of each reaction, or thrust, is carried into a buttress, which
Structural tubing is being used more frequently in modern construction (Art. 6.30). It is often preferred to other steel members
A two-hinged arch has hinges only at the supports (Fig. 4.2a). Such an arch is statically indeterminate. Determination of the
End bearings transmit the reactions from trusses to substructure elements, such as abutments or piers. Unless trusses are supported on
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 sequence may serve as a guide to the design of truss bridges: Select span and general proportions of
The following shapes for truss members are typically considered: H sections, made with two side segments (composed of angles or
