This paper presents a conceptual framework to define seismic resilience of communities and quantitative measures of resilience that can be useful for a coordinated research effort focusing on enhancing this resilience. This framework relies on the complementary measures of resilience: “Reduced failure probabilities,” “Reduced consequences from failures,”(More)
This study examines the fragility curves of a bridge by two different analytical approaches; one utilizes the time-history analysis and the other uses the capacity spectrum method. The latter approach is one of the simplified nonlinear static procedures recently developed for buildings. In this respect, a sample of 10 nominally identical but statistically(More)
DuraNode is a sensor node for real-time monitoring the health of civil engineering structures such as highway bridges and skyscrapers. It is specially designed to take civil engineers’ requirements into account. To meet their requirements DuraNode has a dualmicrocontroller architecture sharing a FIFO memory. Evaluation shows that DuraNode has many(More)
In this paper a simulation approach to modeling the linkages between physical infrastructure systems and the urban economy is developed. A simulation approach based on probabilistically specifying the key model relationships is effective for situations that involve substantial uncertainty, and is particularly suited to assessing risk from natural hazards.(More)
This study develops and investigates reliability and accuracy of wireless MEMS (Micro Electro Mechanical Systems)-type sensors for real-time seismic monitoring of bridges. The wireless capability added to the developed MEMS Sensors makes it possible to avoid the use of lengthy multiple cables for the bridge monitoring. This study introduces two types of(More)
The objectives of this research are to characterize urban building damage , using a comparative analysis of remote sensing imagery acquired before and after an earthquake event, and to develop preliminary damage detection algorithms for locating collapsed urban structures. R emote sensing technologies are emerging as useful post-earthquake damage evaluation(More)
This document provides an assessment of the current state of advanced airborne and spaceborne remote sensing and ground-based technologies applicable to the analysis of seismic risk and vulnerability of buildings and lifeline systems. Continuous Global Positioning System (GPS) ground deformation monitoring and seismological networks provide critical(More)
This paper discusses issues of using wireless sensor systems to monitor structures and pipelines in the case of disastrous events. The platforms are deployed and monitored remotely on lifetime systems, such as underground water pipelines. Although similar systems have been proposed for monitoring seismic events and the structure health of bridges and(More)
