When designing a column against buckling, how do you decide weather to use the Johnson or Euler formula in your calculations when computing the critical buckling load?
Derive the elastic lateral torsional buckling formula of a
cantilever I-beam subject to a concentrated load at the end. The
load is applied at the top of the flange.
A circular Euler column with one end fixed and the other pinned
(or hinged or simply-supported) is under a compressive axial load.
Given the length L of the column and bending rigidity EI, what is
the buckling load Pcr ?
Consider four identical circular Euler columns under a
compressive axial load with a) one end fixed and the other pinned
(or hinged or simply-supported), b) both ends fixed, c) both ends
pinned (or hinged or simply-supported), d) one end fixed and the
other free. What are the buckling loads Pcr for each one and which
one is the strongest against buckling? Given are: the length L of
the column and bending rigidity EI, ?
Q4: Experiments were conducted to determine the safe buckling
load on columns with T-section 100 mm × 100 mm × 10 mm with
different support conditions. When both ends of the columns are
fixed, safe crippling load carried by the column was found to be 60
× 103 N. Suggest the length for other three columns for the same
crippling load when the support conditions are changed to one end
fixed but the other end free, both the ends hinged...
