Steel: Braced Frame Connections

Description

Properly designed steel braced frames provide lateral strength and stiffness, as well as deformation capacity, such that the structure’s performance is reliable. Seismic loading can result in large forces in members and their connections, as well as deformation demands in braces, their connections, and the beam-to-column connection. Special Concentrically Braced Frames accommodate frame movement through brace buckling, which can impose additional connection deformations; this system also benefits from distributed yielding, including some connection contribution. This presentation will address:

  • Designing gussets for strength
  • Proportioning gussets for ductility
  • Rotation demands at beam-to-column connections
  • Accommodating brace buckling in SCBF
  • When to worry about the “chevron effect” (and when not to)

  • Course will award 1.5 hours of continuing education
  • This course is Diamond Review approved in 49 states. New York does not accept hours from recordings.
Please note: This webinar is part of the Seismic Connections Series and is not included in the NCSEA Webinar Subscription. The registration fee for the Series is $595 for members ($900 for nonmembers), which includes all 9 hours of education.

NCSEA Webinars and Digital Events Cancellation and Refund Policies

Webinar Cancellation

By NCSEA: If a webinar is canceled by NCSEA, all registered attendees will be notified via email. NCSEA will issue a full refund if the event cannot be rescheduled. If the event is rescheduled and a registrant can not attend on the rescheduled date, NCSEA will offer a credit in the amount of the purchase price.

By Registrant/Attendee: Cancellations must be made at least 24 hours in advance of the webinar (or the first webinar in the case of a series or bundle) and in writing via email ( ncsea@ncsea.com) with the subject line "NCSEA Webinar Cancellation" and include the following in the body of the email: Title of Webinar, Order/Invoice Number, Name of Registrant, and Reason for Cancellation. No telephone refund requests will be accepted.

If the request has been approved, NCSEA can do one of the following:
  • Refund the amount back to the original order payment method (a $25 cancellation processing fee will be assessed)
  • Issue a full credit on the purchaser’s account that can be used towards a future webinar/event.

If you are unable to attend the webinar and the cancellation deadline has passed, a recording will be available (in most cases) in the Education Portal after the webinar has concluded.
Refunds are not granted due to attendee technology issues. It is your responsibility as the webinar attendee to test your computer setup prior to the start of the webinar.
