Tag: Compression Members Columns and Other Compression Members

The principal factors governing the proportioning of members carrying compressive forces are overall column buckling, local buckling, and gross section area. The effect of overall column buckling depends on the slenderness ratio Kl/ r, where Kl is the effective length, in, of the column, l is the unbraced length, and r is the least radius of gyration, in, of the cross section. The effect

Tag: Compression Members Stress and Strain

Structural capacity, or ultimate strength, is that property of a structural member that serves as a measure of is ability to support all potential loads without severe cracking or excessive deformations. To indicate when the limit on load-carrying usefulness has been reached, design specifications for the various structural materials establish allowable unit stresses or design strengths that may not be exceeded under  maximum loading.

Tag: Compression Members Member Design Example-LRFD

The design of a truss hanger by the AASHTO LRFD Specifications is presented subsequently. This is preceded by the following introduction to the LRFD member design provisions. LRFD Member Design Provisions Tension Members. The net area, An, of a member is the sum of the products of thickness and the smallest net width of each element. The width of each standard

Tag: Compression Members Truss Member Details

The following shapes for truss members are typically considered: H sections, made with two side segments (composed of angles or plates) with solid web, perforated web, or web of stay plates and lacing. Modern bridges almost exclusively use H sections made of three plates welded together. Channel sections, made with two angle segments, with solid  , perforated web, or web of

Compression members should be configured so the main elements of the section are connected directly to the gusset plates, pins, or other members. For members consisting of parts connected by lacing or solid cover plates, the minimum thickness of the web plate, should not be less than: Outstanding Elements In Compression The width, in, of the outstanding elements of compression

Tag: Compression Members Criteria for Built-Up Compression Members

Compression members should be designed so that main components are connected directly to gusset plates, pins, or other members. Stresses should not exceed the allowable for the gross section. The radius of gyration and the effective area of a member with perforated cover plates should be computed for a transverse section through the maximum width of perforation. When perforations are

Tag: Compression Members Built-Up Compression Members

Design of built-up compression members should comply with the basic requirement for prevention of local and overall buckling of compression members as summarized in Arts. 6.16 and 6.23. To ensure, however, that individual components, such as plates and shapes, of a built-up member act together, the AISC ASD and LRFD specifications for structural steel buildings emphasize proper interconnection of the components. Many of the
