The development and evolution of any system–person, organization–nation depends on how the system succeeds to bridge the gap between what the system knows and what the system does (with the knowledge). We call this the gap between knowing and doing or the knowing-doing gap. If the system does not do what it knows, it will lose out in competition with other systems, its relative performance in...

Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake &#10 &#10events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...

Performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (VCE) could be considered as one of the main causes of bridges collapse. In most of bridge design codes, for seismic analysis of bridges, VCE is not taken into account or a distinguished method isn’t presented for assessment of VCE. In the present work, the effect of VCE on two existing...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...

Flood-induced scour is the principal cause of bridge failure worldwide. Nevertheless, risk assessment still based on visual inspections, which may be affected by human errors and cannot performed during flood peaks. This problem, together with simplifications in estimation, might misclassification risk, unnecessary closures or recourse to avoidable mitigation measures. Structural-health-monitor...

As part of a study to develop a comprehensive bridge management system for the Indiana Department of Highways (IDOH), a bridge performance prediction model using the Markov chain was developed. The model can be used to predict the percentages of bridges with different condition ratings as well as to develop performance curves of bridges. The Markov chain, a probability-based method, was used in...
