SUBJECT: Structural Steel Design
TOPIC: Axially Loaded Columns & Other Compression Members
SUB TOPIC: Euler’s Stress for Hinged - Columns
Sample problem:
A hollow mild steel tube 5 m long, 4 cm internal diameter and 5 mm thick is used as a strut with
both ends hinged. Find the crippling load and safe load taking FOS as 3. Taking E = 2 x 105
N/mm2.
Explanation with solution and answer:
By use of Euler critical load formula we can find the crippling load in strut.

𝐸𝑢𝑙𝑒𝑟 𝑐𝑟𝑖𝑡𝑖𝑐𝑎𝑙 𝑙𝑜𝑎𝑑, 𝑃 =
𝐿2
Where:
L = length of strut = 5m = 5000 mm
E = 2 x 105 N/mm2
I = moment of inertia of the section = I big - I small
