Question

4. In a universal beam section, b = 40 mm and t = 2 mm for its flange element. Calculate the theoretical
local buckling stress of this element in compression?

Expert Solution

Step 1: Introduction

The width of the flange section is $b equals 40 space text mm end text$ .

The thickness is $t equals 2 space text mm end text$ .

The formula to calculate the theoretical local buckling stress is given by,

$f subscript o l end subscript equals k fraction numerator pi squared E over denominator 12 open parentheses 1 minus nu close parentheses squared end fraction open parentheses t over b close parentheses squared$

Here, $E$  is Young’s modulus, $t$  is the plate thickness, $b$  is the plate width, $k$ is is a plate buckling coefficient which depends on the support conditions and $nu$  is Poisson’s ratio.

The value of $k$ is $4 minus 4.5$ . Take $k equals 4$ .

Assume $E equals 2 cross times 10 to the power of 5 space text N/mm end text squared$ and $nu equals 0.30$ .
