What is a Whitmore section?

What is a Whitmore section?

The Whitmore section was described by Whitmore (1952) as a reasonable method for approximating the maximum tensile (and compressive) elastic stress incurred in a riveted gusset plate by the axial force in a connected brace, and found widespread use from the late 1970s (Thornton and Lini 2011).

What is a gusset plate in construction?

Gussets, sometimes known as gusset plates, are metal sheets of various thicknesses used for either joining two or more components together or strengthening joints. These components include beams, girders, truss members, chords, and columns.

What is the difference between gusset plate and stiffener plate?

Steel gusset plates generally support, or reinforce the connection of two major structural steel parts, such as when bolting and/or welding bridge beams or trusses to adjoining load bearing, bridge column supports. Some might refer to these as “stiffeners” rather than gussets. …

Is a gusset plate?

A gusset plate is a thin metal object, typically made of steel, that is used to affix independent members of a structure to each other or to a beam to aid alignment. Gusset plates are used in joint, bend or otherwise disjointed structural locations that require additional support to withstand stresses.

Which is not a compression member?

Which of the following is not a compression member? Explanation: Strut, boom and rafter are compression members, whereas tie is a tension member. Explanation: Generally, ISHB sections are used as compression members.

What is stiffener plate?

Stiffeners are secondary plates or sections which are attached to beam webs or flanges to stiffen them against out of plane deformations. Almost all main bridge beams will have stiffeners. Deep beams sometimes also have longitudinal web stiffeners.

Why do we use gusset plate?

Gusset plates are used to connect beams and columns together or to connect truss members. They can be either the only way of connecting the beam and columns or they can be used with bolts and welds. Gusset plates provide an easy way to retrofit structures that can no longer safely support the applied loads.

Why is built up section used Sanfoundry?

Why is built up section used? Explanation: Size and shape of rolled sections are limited because of limitation of rolling mills. When rolled section do not furnish required sectional area or when special shape or large radius of gyration is required in two different direction, a built up section is used.

How do you calculate net effective area?

The net area at any section is equal to the gross area minus the deduction for holes at that section. The deduction for the hole is the product of the hole diameter and the thickness of the material.
