This live web event has ended. Thank you for attending.

Description

This presentation will cover Examples 1 and 7 from Volume 3. Example 1 addresses concrete shear walls, focusing on key concepts including: desired behavior of concrete walls, design for flexure, bar cut-offs and lap splices, design for shear, effect of gravity framing, detailing of wall boundaries, detailing of coupling beams, and wall stiffness. The presentation will draw on observations and lessons learned from past earthquakes, in addition to code requirements and recommendations from research. This presentation will also cover design of diaphragm, chords and collectors using a simplified approach, to comply with the requirements of IBC 2018. Conclusions based on the results are presented at the end of the example.

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.
