Design Of Steel Structures

Step 1: Lacing force concept.
The transverse shear carried by lacing system is taken as of the axial load in the column.

Step 2: Calculation.
Since lacing is provided on both faces: But by code provisions, design is generally based on **10% of axial load shared by lacing members in total**, hence:

Step 3: Conclusion.
The lacing must resist a transverse shear of .
