What is LX LY LZ in STAAD?

LX = Effective Length for Lateral Torsional Buckling (as per Table-15, Section 8.3.1) LY = Length to calculate Slenderness Ratio for buckling about local Y axis. LZ = Length to calculate Slenderness Ratio for buckling about local Z axis.

What is postprocessing tab in STAAD *?

Postprocessing tab in STAAD will provide you the results of the analysis you have carried out. The support reactions, support displacement, bending moments, shear forces, axial forces, torsion can be seen and the structure can be designed for the forces and moments occurring in the governing load combinations.

How do you find displacement in STAAD pro?

After analysis, when ie check displacement in a beam by going to Reports>section displacement. it shows max displacement along with global displacement in the Y direction.

What is ky and kz in STAAD?

STAAD includes Ky, Kz, Ly, Lz ,MAIN and TMAIN parameters under design. These parameters govern the slenderness calculation and allowable axial compressive stress of a member in design. Ky and Kz are the effective length factor along Y and Z axes respectively.

What is relative displacement in STAAD?

A straight line is drawn joining the displaced positions of the start and end nodes for the beam. The displacement at all intermediate section locations are reported relative to that straight line.

How is deflection calculated in STAAD?

in staad you can check this with just click on the postprocessor after the run analysis, you can see the deflection along X,Y and Z axis of the node for load cases which you selected/assigned. You can also check with by double click on the member and tab to deflection.

What is UNL in STAAD pro?

UNL (unsupported length) parameter is given in STAAD to design the steel member for the lateral buckling of compression flange. It is used in the design of column and beams.

What is the formula of slenderness ratio?

The slenderness ratio is calculated by dividing the column length by its radius of gyration. The slenderness ratio differentiates short column from long or slender column.
