Task – Shear Walls
* Objectives:
- Improve understanding of the cyclic behavior of full-scale
shear walls of different construction
- Expand upon City of Los Angeles project at UC-Irvine
- Correlate with Task Shake Table Tests
* 46 samples: 16’ x 8’, 6.5’ x 8’, 3’ x 8’
* Two large scale multi-story wall tests - 16’ x 17’
* Main test variables:
- Gravity loads, nail types, grade of framing lumber, staples,
hold-downs, aspect ratio
