Most of the existing strong motion instrumentation on civil engineering structures is installed and operated as federal, state, university, industry or private applications, in many cases operated as a closed system. This affects co-operation and data exchange, hampering the acquisition of strong motion and structural data, sometimes even within a single country. There is a need to inform engineers of existing strong motion data and to improve the accessibility of data worldwide. This book should play a role in fulfilling such a need by disseminating state-of-the art information, technology and developments in the strong motion instrumentation of civil engineering structures. The subject has direct implications for the earthquake response of structures, improvements in design for earthquake resistance, and hazard mitigation.
