Description

Structural engineers designing structures to resist earthquake loading rely on ductile behavior to absorb seismically-induced loads, and yet brittle fractures have been observed after earthquakes. These apparent paradoxes can be understood when the role of shear stresses and ductility is properly understood. Notches and constraint, known to be problematic when ductility is desired, can also be explained in terms of shear stresses. Designing structural systems to enable the development of shear stresses is essential if ductility is desired. This presentation will give insight into how ductility can be achieved and provide some insight into how Mohr's Circle can be used to easily explain ductility.

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 Ductility and Brittle Fracture Series and is not included in the NCSEA Webinar Subscription. The registration fee for the Series is $395 for members ($500 for nonmembers), which includes all 3 hours of education.

Thank You to our Sponsor!

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.
