Braced wall lines greater than 16 feet shall have a minimum of 4 braced wall panels. Option 3) 4 is correct.
Braced wall lines are essential components in structural engineering, particularly in resisting lateral forces such as wind and seismic loads. When a building has braced wall lines with a length exceeding 16 feet, there's a need to ensure adequate structural support to counteract these lateral forces.
To address this, the International Residential Code (IRC) and similar building codes stipulate that when a braced wall line exceeds 16 feet, a minimum of 4 braced wall panels is required. These panels are strategically placed to provide necessary reinforcement against lateral forces, ensuring the structural integrity and safety of the building.
In conclusion, when dealing with braced wall lines greater than 16 feet, the minimum requirement for braced wall panels according to building codes is 4. This ensures that the building can effectively withstand lateral forces and maintain structural stability.
