Presentation Outline: Current practices to accommodate lateral drift of non-bearing cold-formed steel stud exterior systems cannot fully isolate the exterior system to receive zero damage in a seismic event since the drifts can often exceed three inches per floor.  In-plane lateral drift and out-of-plane lateral drift are accomplished in many different ways.  With various types of joints, tracks, and slotted clips both of these drifts can be achieved, but it can be difficult to accomplish both drifts effectively where walls intersect.  Detailing must allow for inelastic building drifts without failure of the exterior system that would result in a falling hazard.  This webinar adPDHsdressed the various ways to accommodate large lateral drifts in exterior and interior cold formed steel framing systems.

This Webinar includes:

  • The science behind lateral loading and movement of buildings.
  • Amounts of drift to expect with various structural systems and building types
  • Current practices for accommodating building drift on both interior partitions and exterior walls
  • Other methods for reducing drift related damage
  • Specific details and methodologies for problem areas such as wall intersections and building corners

Why you should attend?

  • In areas where there are frequent moderate earthquakes, building owners want to reduce the amount of damage and cost of repairs.
  • Improper detailing of drift connections can lead to life-safety issues
  • Proper detailing and installation of these systems are critical to their proper performance during a high wind or seismic event.
