The average shear stress for rolled steel beam section, is
-
For a rectangular section, the ratio of the maximum and average shear stresses, is
-
To keep the intensity of bearing pressure between the column base and concrete compressive and to vary from zero to
, the ratio of the moment M to the axial load P should be -
The cross-section of a standard fillet is a triangle whose base angles are
-
Secant formula for direct stress in compression, is applicable only for slenderness ratio upto
-
A second horizontal stiffener is always placed at the neutral axis of the girder if the thickness of the web is less than
-
The rolled steel I-sections are most commonly used as beams because these provide
-
The thickness t of a single flat lacing should not be less than
-
For the steel member exposed to weather and accessible for repainting, the thickness of steel should not be less than (excepting the webs of Indian Standard rolled steel joists and channels).
