Projects : Task Order 36

Development of Technical Brief on Structural Design Issues:
Seismic Design of Structural Wood Diaphragm Systems

SUMMARY

The primary objective of this task was to produce a new techbrief addressing the analysis, design, detailing, and construction of structural wood roof, floor and wall diaphragm systems for use as lateral load-resisting systems in buildings in areas of moderate to high seismic activity.

This techbrief synthesized model building code requirements and leading practitioner-recognized techniques, resulting in clear and concise analysis, design, and construction guidance on structural wood diaphragm systems for use by practicing structural engineers.
