Column Buckling
- Thread starter peach
- Start date
The Australian Bridge Design Code gives the following formula for a reinforced concrete column:<br>
<br>
Nc = (pi^2/Le^2)*(200*d*.6*Mub)/(1+Beta_d) where<br>
<br>
Nc = Buckling load<br>
Pi = pi or 22/7<br>
Le = effective length of column<br>
d = depth to outermost layer of tensile steel<br>
Mub = moment corresponding to nuetral axis depth of 0.6*d<br>
Beta_d = ratio of dead load to total load.<br>
<br>
Hope this helps!<br>

Indian Standards Gives a method for the design of slender RCC Columns subjected to biaxial bending. I have a software called COLDES which is capable of designing such columns. email me roynshenoy@vsnl.com or visit and see the software section.<br>
