RE: Lateral Bracing

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Ahh, a technical question.  Bless you...

If you are using tension-only rod bracing, you could also consider using single-angle, tension-only, "X" bracing. The detailers detail the angles with 2 bolts (minimum) at each end, and 1/8" short of the theoretical bolt to bolt length for the rod length. The angle is tightened when the angle is drawn tight by driving the bull pin in to allign the holes. Once bolts are placed in one hole, the bull pin is removed and the other bolt is installed.

Most of our projects are steel framed, one to three stories in a low seismic zone. We try to use X-bracing with rods and turnbuckles to resist lateral loads but find it difficult to conceal the turn buckles in the walls. ?Type 2? connections are used on projects where the x-bracing won?t work. What is the most popular and economical lateral bracing system to use? What are some other practical types of x-bracing material to use?

Thanks in advance
