2012 IBC Section 1604.3 requires that structures be designed to have adequate stiffness to limit deflections and lateral drift. This web seminar provides you with practical guidance on how to comply with this requirement and covers the following topics:

1. How to perform an accurate analysis for service level lateral loads for the purpose of building drift considerations.

2. Understanding what racking levels under different magnitudes of loading will cause damage that can be objectionable to the building occupants.

3. Explanation of different approaches to assessing the performance of a building under service level loads, with a focus on the analysis requirements and mean recurrence intervals of wind and seismic events applicable to building drift design and control.

4. Methods for designers to make informed decisions about how to proportion the building's lateral force-resisting system to control damage caused by excessive drift from service level lateral loads caused by wind storms and seismic events.
