Slender beams (concrete beam: EC2)
|
Second order effects associated with lateral instability may be ignored if beams are within the geometric limits given by the following; |
||
| L0t |
|
50*bcomp/(h/bcomp)1/3 |
| and | ||
| h/bcomp |
|
2.5 |
| where | ||
| L0t |
|
distance between torsional restraints, taken in Tekla Structural Designer as the distance between faces of supports |
| h |
|
total overall depth of the beam at the centre of L0t |
| bcomp |
|
width of the compression flange of the beam ( = bw for rectangular sections and beff for flanged beams) |
|
||
|
If either of the above checks fail then a Warning is displayed. |
