Question
Download Solution PDFThe effective length of lateral buckling for a simply supported beam under normal loading conditions, provided torsional restraint as fully restrained and warping restraint as both flanges fully restrained should be _______.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe buckling load (Pcr)of a steel column is
\({P_{cr}} = \frac{{{\pi ^2}EI}}{{L_{eff}^2}}\)
where EI = flexural rigidity, Leff = effective length of the column
The effective length of a column (Leff)
It is the length of the column between points of zero moments.
IS:800 – 2007 uses ‘L’ for unsupported length and ‘kL’ for an effective length
where
\(\left\{ {\begin{array}{*{20}{c}} {k = 2,\;for\;a\;cantilever\;column\;}\\ {k = 1,\;for\;both\;ends\;hinged\;column\;}\\{k = 0.8,\;for\;one\;end\;fixed\;and\;other\;end\;hinged\;}\\{k = 0.7,\;for\;both\;end\;fixed\;and\; fully\;restraint} \end{array}} \right.\)
