What is a Whitmore section?
The Whitmore section is used to determine the peak tension or compression stress of an uneven stress distribution at the end of the joint.
What is the size of gusset plate?
Dimensions of the gusset plates of 850 mm x 700 mm x 13.3 mm and 850 mm x 700 mm x 9.8 mm, the material properties and the boundary conditions taken from [5] are used.
How do you measure a gusset plate?
In design, gusset plates are treated as rectangular, axially-loaded members with a cross section Lw × t, where Lw is the effective width, and t is the plate thickness. The effective width is calculated by assuming the stress spreads through the gusset plate at an angle of 30°.
What is maximum pitch distance?
Explanation: Pitch shall not be more than 16t or 200mm, whichever is less in tension member where t is thickness of thinner plate. Pitch shall not be more than 12t or 200mm, whichever is less in compression member, where t is thickness of thinner plate.
Why is it called a gusset?
The original gussets were used in chain mail or armor, to cover unprotected areas. The word comes from the Old French gosset, “armhole,” or “piece of armor for the armpit.”
What is the maximum pitch for a staircase?
OSHA regulations for industrial stairs allow a maximum of 45 degree stair slope. IBC requirements for egress stairs allow up to a 32.4 degree angle for the stair slope.
What is meant by shear lag?
On account of shear strain, the longitudinal tensile or compressive bending stress in wide beam flanges diminishes with the distance from the web or webs; this stress diminution is called shear lag.
What is gusset base?
A gusseted base consists of a base plate of reduced thickness, two gusset plates and cleat angles are placed on column flanges.
Why are gusset used?
In sewing, a gusset is a triangular or rhomboidal piece of fabric inserted into a seam to add breadth or reduce stress from tight-fitting clothing. Gussets were used at the shoulders, underarms, and hems of traditional shirts and chemises made of rectangular lengths of linen to shape the garments to the body.
