Question

6. Column with rectangular section is fixed at the base and free at the top and it subjected to a load of 4000 kN, as shown below. Elastic modulus of material is E=30 GPa, and safety coefficient for the stability of the column is [nst]=4.0. The compression strength of the column is met. Try to determine the maximum height of the column.

Answer 1

Answer:

The maximum load at which the column tends to have lateral displacement or tends to buckle is known as buckling or crippling load. Load columns can be analyzed with the Euler’s column formulas can be given as

For both end hinged, n=1

For one end fixed and other free, n=1/2

For both end fixed, n=2

For one end fixed and other hinged, n=√2

Effective Length:

Calculation:

Since both the ends are hinged

Then
