Wireless Vibration Monitoring for Damage Detection of Highway Bridges
The development of low-cost wireless sensor networks has resulted in resurgence in the development of ambient vibration monitoring methods to assess the in-service condition of highway bridges. However, a reliable approach towards assessing the health of an in-service bridge and identifying and localizing damage without a priori knowledge of the vibration response history has yet to be formulat...
متن کاملSeismic radiation from regions sustaining brittle damage
Dynamic changes of elastic moduli in source volumes are predicted to produce "damagerelated-radiation" associated with products of the changes of elastic moduli and total elastic strain components in the source volume [Ben-Zion and Ampuero, 2009]. Decreasing elastic moduli (as produced by brittle deformation of low-porosity rocks and explosions) increase the radiation to the bulk, while increas...
متن کاملSeismic radiation from regions sustaining material damage
S U M M A R Y We discuss analytical results for seismic radiation during rapid episodes of inelastic brittle deformation that include, in addition to the standard moment term, a damage-related term stemming from changes of elastic moduli in the source region. The radiation from the damagerelated term is associated with products of the changes of elastic moduli and the total elastic strain compo...
متن کاملA methodology for Determining the Seismic Vulnerability of Old Concrete Highway Bridges by Using Fragility Curves
Past earthquakes have demonstrated that old RC bridges may be seismically vulnerable. Bridge responses during the last decades illustrated the necessity of the seismic assessment of bridges especially those which were designed with old codes. In this research an existing concrete bridge representative of the most common bridges in the highway system in Iran are studied. Push over and nonlinear ...
متن کاملDamage Accumulation in Unreinforced Masonry Due to Seismic Loading
Masonry has low cohesive strength and is susceptible to the brittle failure, when subjected to induced tensile stresses. It fails due to lateral tensile stresses even when masonry prisms are tested in uni-axial static compression and the stress-strain curve remains almost linear up to failure. Although masonry normally resists compressive forces, under lateral in-plane cyclic loads some parts o...
