Capacity Design • To guarantee the desired performance at the Lifeprevention level • Explicit selection of a mechanism of inelastic deformation • Explicit recognition of effects caused higher modes of response • Larger than forces obtained from DBD analysis (1 st mode!) • Larger floor accelerations
Test Structure 63’-0” 21 m PT wall Gravity columns Flange wall Cantilever web wall • 7-story building slice with cantilever wall as the lateral force resisting system • Tallest building structure ever tested on a shaketable • Single axis of input ground motion in the plane of the wall • Phase 1 Testing: 12 ft. long rectangular wall • Phase 2 Testing 14 ft. 7 in. long T-wall
