CUREe-Caltech Woodframe Project - Task 1.4.3
Seismic Behavior of Wood Cripple Walls

Specimen#25: 1:2 Stepped cripple wall subjected to the near-fault ground motion protocol (Krawinkler et al 1999)
Tested on 12/05/00

Test Matrix: 100plf gravity loading with stucco
(click photos to enlarge)
Fully Assembled Test (North face)
Existing cracks in stucco prior to testing
Progressive cracking in stucco - upon pulling (uphill) to a displacement of 1.422"
Split sill at uphill panel - at the end of testing

Lateral Force-Displacement Response of Specimen #25 (compared with Specimen #24 - similar detailing - subjected to the ordinary ground motion protocol)
