Based on the experimental investigation, it is shown that the gypsum sheathing board of thickness (tb) 12.5 mm with intermediate fastener spacing (df) 300 mm is sufficient to inhibit the LTB of the inverted hat shaped CFS studs. In addition, the analytical investigations were also performed to check the strength of the sheathing bracing. A series of four pilot tests were conducted on the trapezoidal girder with a metal decking top lateral bracing system. The purpose of these tests was to examine whether the use of metal decking as a top lateral bracing system would produce similar increases in bending strength that the X-brace system did.

For example, 20-gauge interior wall partition studs have a thickness of 0.76 mm (30 mil), while 20-gauge ... My question is: What details have you seen in this situation? Should I be designing the cross bracing to take lateral load? If so, I would need much larger members (probably HSS). In buildings I've worked on in the past, the wall was positioned outside of the steel which allowed the steel studs to be continuous, and the bracing to be continuous.

This is because plan bracing provides lateral restraint, i.e. it stops the compression flanges of beams from moving sideways. Plan bracing takes the form of diagonal members, usually angle sections, connecting the compression flanges of the main beams, to form a truss when viewed in plan. This makes a structure that is very stiff in response to lateral movement. LGS Concept LGS framing with design principles General approach to design; Beams (joists) require torsional restraints, lateral bracings at intervals or alongside of the beam. Bracing will minimize the lateral and torsional deformations and will transfer Shear and torque forces to other members. 27.
