Element 1 - Testing & Analysis
Task No. 22.214.171.124 Anchorage of Woodframe Buildings
PI: James A Mahaney (Wiss, Janney, Elstner Associates, Inc)
Sill plates bolted to foundations have not performed well in past earthquakes. Observations following earthquakes and laboratory tests indicate that the principal failure mode is longitudinal splitting of the sill plates at anchor bolts.
The main objective is to improve the understanding of the cyclic behavior of sill plate-to-foundation anchorage connections for a wide range of anchorage configurations. Another objective is to develop sill plate connections that do not exhibit brittle type failures.
This task is divided into a literature review component and a laboratory testing component.
