-
If the moment of inertia of a section about its axis is I and its effective sectional area is A, its radius of gyration r about the axis, is
-
The critical load for a column of length I hinged at both ends and having flexural rigidity El, is given by
-
Pick up the correct statement from the following:
-
A structural member subjected to compressive stress in a direction parallel to its longitudinal axis, is generally known as
-
The equivalent axial tensile load Pe, which produces an average axial tensile stress in the section equivalent to the combined stress due to axial tension P and bending M, at the extreme fibre of the section, is given by (where Z is the section modulus of the section).
-
Live load
-
The most economical section for a column, is
-
If the depth of two column sections are equal, then the column splice is provided
-
The distance between e.g. of compression and e.g. of tension flanges of a plate girder, is known as
