1. Issue Team Recommendations for Wood & CFS
Mid-rise light-frame shear wall buildings
New soft-story structures
New hillside structures

Light-frame structures with masonry veneer

2. Mid-rise Light-frame Shear Wall Buildings: Performance, Design, Detailing

3. Mid-rise Light-frame Shear Wall Buildings: Performance, Design, Detailing
Issues:
Extended into mid-rise construction without adequate knowledge of seismic performance
Is adequate safety provided?
How do we design for performance?
What tools are needed for multi-story stacked shear wall analysis and design?

4. New Soft-story Structures: Reconsider Irregularity Implications

5. New Soft-story Structures: Reconsider Irregularity Implications
Issues:
Analysis and shake table testing consistently shows that light-frame construction exhibits extreme soft story behavior, regardless of design to avoid this behavior
Study is needed to consider what is achieved by current code limitations and practical ways to approach new building design
