Efficiency of scalar and vector intensity measures for seismic slope displacements

Gang WANG

Frontiers of Structural and Civil Engineering 2012, Volume 6, Issue 1, Pages 44-52 doi: 10.1007/s11709-012-0138-x

Abstract: Ground motion intensity measures are usually used to predict the earthquake-induced displacements inprediction models as well as the ground motion selection criteria for time domain analysis of seismic slope displacements

Structural health monitoring with fiber optic sensors

F. ANSARI

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 2, Pages 103-110 doi: 10.1007/s11465-009-0032-y

Abstract: Optical fiber sensors have been successfully implemented in aeronautics, mechanical systems, and medical applications. Civil structures pose further challenges in monitoring mainly due to their large dimensions, diversity and heterogeneity of materials involved, and hostile construction environment. This article provides a summary of basic principles pertaining to practical health monitoring of civil engineering structures with optical fiber sensors. The issues discussed include basic sensor principles, strain transfer mechanism, sensor packaging, sensor placement in construction environment, and reliability and survivability of the sensors.
