Staggered Trusses
In an effort to provide a structural-steel framing system with a minimum floor-to- floor height for multistory residential construction, the staggered
Specifications
The design of truss bridges usually follows the specifications of the American Association of State Highway and Transportation Officials (AASHTO) or
Specifications and Loadings for Cable-Suspended Bridges

Space Frames
These represent one of the more efficient uses of structural materials. Space frames are threedimensional lattice-type structures that span in
Span Lengths and Deflections
Many designers believe that steel girders, because of their lower weight per foot, should have longer spans than concrete beams for
Span Growth of Suspension Bridges
Figure 15.25 shows the growth of maximum spans by year. It is obvious that in the 60-year period from the Golden
Slope-Deflection Method
One of several displacement methods for analyzing statically indeterminate structures that resist loads by bending involves use of slope-deflection equations.
Skewed Bridges
To reduce scour and to avoid impeding stream flow, it is generally desirable to orient piers with centerlines parallel to direction
