When performing the slenderness check, the user may evaluate the following values:
|
Ly |
System length for buckling around y axis |
|
ky |
Buckling ratio (used during code check) for buckling around y axis |
|
ly |
Buckling length for buckling around y axis ly = Ly * ky |
|
Lam y |
Slenderness around y axis
Iy : buckling length for buckling around y axis iy : radius of gyration around z axis |
|
Lz |
System length for buckling around z axis |
|
kz |
Buckling ratio (used during code check) for buckling around z axis |
|
lz |
Buckling length for buckling around z axis lz = Lz * kz |
|
Lam z |
Slenderness around z axis
Iz : buckling length for buckling around z axis iz : radius of gyration around z axis |
|
l LTB |
The lateral-torsional buckling length l LTB = kLTB * L LTB |
Second order buckling ratio of the slenderness check can be obtained by means of:
Open service Steel:
either using tree menu function Steel,
or using menu function Tree > Steel.
Select function Slenderness.
In the Property window select the values that should be displayed and adjust the other parameters as required.
The diagrams are displayed on the screen.
Note: More information about displaying of results can be found in chapter Results > Displaying the internal forces in the Reference manual for Nemetschek SCIA.
