This book describes tests performed on model adobe buildings used to evaluate seismic damage mitigation techniques applicable to the retrofitting of historic and culturally significant adobe structures. Part of the Getty Seismic Adobe Project (GSAP), the three-year program outlined in this volume was designed to develop and test minimally invasive, inexpensive, and easily implemented methods of protecting such structures from severe earthquake damage. The authors identify typical failure modes of adobe structures and describe specific retrofit techniques to help minimize such failures. Extensive photographic documentation is included.
