Bolting
Most field connections are made by bolting, either with high-strength bolts (ASTM A325 or A490) or with ordinary machine bolts (A307 […]

In new work, ASTM A307 bolts or high-strength bolts used in bearing-type connections should not be considered as sharing the stress
Bridges should be designed so that a total movement due to temperature change of 11â„4 in per 100 ft can take
Beams are structural members subjected to lateral forces that cause bending. There are distinct relationships between the load on a
For a member subjected to flexure, the bending strength depends on the shape of the member, width/ thickness or depth/ thickness
AISC ASD Approach. Beams may be supported directly on concrete or masonry if the bearing pressure is within the allowable.
There are many cases where beams are supported only at the bottom flange. In one-story buildings, for example, beams often
Table 11.29 lists the allowable stresses for railroad bridges recommended in the AREMA Manual. The stresses, ksi, are related to the
