In This Presentation
This webinar is based upon the design example “Four-story Wood Light-frame Structure” in Volume 2 of the SSDM series. Presentation talks about rigid vs flexible diaphragms and potential problems with torsion in these types of buildings. Presentation includes the design and detailing for a multi-story wood framed shear walls using the continuous tie down system including boundary element and tension rod design. The presentation also includes how to calculate wood frame shear wall deflections. There is a brief discussion on the design and detailing of wood framed trusses and the use of collector trusses. The presentation concludes with a side by side comparison of force-transfer-around-openings (FTAO) using both the SEAOC/Thompson Method and the Diekmann Method.

About the Webinar Series
This series of lunchtime webinars features an in-depth look at design examples from SEAOC’s newly published 2015 IBC Structural/Seismic Design Manual (SSDM) Volumes 1, 2 and 3. This will be your opportunity to hear directly from contributing authors of the example problems as they share their significant expertise and experience in the design area and underlying building code provisions of the new 2015 International Building Code (IBC). With built-in time for audience questions and answers at the end of each session, these unique sessions are sure to be useful to experienced and new engineers alike. All webinars will be held live in January and February 2017.
About the SEAOC Structural/Seismic Design Manual (SSDM)
The SEAOC Structural/Seismic Design Manual (SSDM), throughout its many editions, has served the purpose of illustrating good seismic design and the correct application of building-code provisions. The SSDM has bridged the gap between the treatment of topics in the building code and ASCE 7, the SEAOC Blue Book (Recommended Lateral Force Requirements and Commentary) and real-world decisions that designers face in their practice.
The SSDM uses example buildings to illustrate code-compliant designs engineered to achieve good performance under seismic loading. The examples address the full range of seismic design considerations, from conceptual level through details of connections and load path. In some cases simply complying with building-code requirements does not ensure good seismic response; here the SSSDM makes recommendations for exceeding the minimum code requirements in such cases, with discussion of the reasons for doing so.
The newly released 2015 SEAOC SSDM has updated and revised the examples for consistency with the 2015 edition of the International Building Code. Volumes 1, 2, and, 3 (addressing light-frame, tilt-up, masonry, and reinforced concrete buildings) have had the most significant changes. Learn more and purchase your copies today >
