Beams Seated Atop Supports
There are many cases where beams are supported only at the bottom flange. In one-story buildings, for example, beams often […]

Basic Allowable Stresses
Table 11.29 lists the allowable stresses for railroad bridges recommended in the AREMA Manual. The stresses, ksi, are related to the
Axial Tension
L = length of connection in the direction of loading, in Larger values of U are permitted when justified by tests
Axial-Force Members
In an axial-force member, the stresses and strains are uniformly distributed over the cross section. Typically examples of this type
Basic Allowable Stresses for Bridges
Table 11.16 lists the basic allowable stresses for highway bridges recommended in AASHTO Standard Specifications for Highway Bridges for ASD.
Assumptions for Analysis of Trusses
The analysis of trusses is usually based on the following simplifying assumptions: 1. All members are connected only at their
Arrangement of Members of Plane Trusses-Internal Stability
Based on our discussion in Section 3.4, we can define a plane truss as internally stable if the number and

ASD and LRFD Specifications
The American Institute of Steel Construction (AISC) has developed design specifications for structural steel with two different design approaches: Specification for
ASD versus LRFD
results in lighter or shallower members. For example, LRFD will typically result in material savings in the range of 10 to
