PHASE I RESEARCH REPORT

CKI-09: Design Guidelines for Ductility and Drift Limits

This report summarizes each of the studies that have been conducted in California as a part of the CUREe-Kajima Research Project #5, entitled "Design Guidelines for Ductility and Drift Limits." This research project has been supported by a grant provided by the Kajima Corporation and administered by CUREe (California Universities for Research in Earthquake Engineering). This financial support is gratefully acknowledged.

The report includes:
