Design Methods
The AISI Specification is structured such that nominal strength equations are given for various types of structural members such as beams […]
Structural Steel
Design Considerations
Design considerations for steel railroad bridges differ somewhat from those for highway bridges. Railroad bridges have a higher live-to-dead load ratio
Design Loadings
Bridges must be designed to carry the specified dead loads, live loads and impact, as well as centrifugal, wind, other lateral
Description of Wind Forces
The magnitude and distribution of wind velocity are the key elements in determining wind design forces. Mountainous or highly developed urban
Deformations in Beams
Article 3.18 presents relationships between a distributed load on a beam, the resulting internal forces and moments, and the corresponding
Deflections of Statically Determinate Trusses
In Art. 3.23, the basic concepts of virtual work and specifically the unit-load method are presented. Employing these concepts, this method
Deck Design
For most truss members, the percentage of total stress attributable to dead load increases as span increases. Because trusses are normally
Cutting, Shearing, and Sawing
Steel shops are commonly organized into departments such as receiving, detail material, main material cut-and-preparation, assembly and shipping. Many shops also
Dead-Load Deflection
Although, in general, building codes restrict the magnitude of live-load deflections, they do not contain criteria or limitations relating to dead-load
