Benchmark Studies For Structural Health Monitoring Using Analytical And Experimental Models
… incidents, anomalies due to deterioration and damage during regular operation as well as after an extreme event. Dynamic testing and analysis are concepts widely used for health monitoring of existing structures. Successful health monitoring applications on real structures can be achieved by …

Inelastic seismic behavior of stiffening systems : multi-span simply-supported (MSSS) bridges
… and mass), 41 strong motion records, and several damage criteria are considered and effects of the stiffening parameters variations on the dynamic response of simple stiffening systems are presented. It is shown that on the average the displacement response is lower for stiffening systems, …

Structural Health Monitoring of Adhesively Bonded Joints With Piezoelectric Wafer Active Sensors
… parallel to the surface and could detect damage that would escape some ultrasonic methods. The major focus of this research was directed towards the electromechanical impedance method for disbond detection. The electromechanical impedance (EMI) method was modeled extensively with …

Port Infrastructure Resilience through Combined Wind-Surge Demand Characterization
… effect of waves on dockside container cranes. A damage index prediction tool that considers both maximum wind speed and storm surge height is developed and applied to historical hurricane data for effectiveness. Comparisons of the new damage index with traditional damage indices based solely on …

Experimental Damage Diagnosis of a Model Three-Story Spatial Frame
Structural damage can be induced by a variety of events from short-term abnormal stresses to long-term natural aging. Detection of changes in a structure's ability to withstand subsequent loads can aid decisions on safety, repair, rehabilitation, and demolition. Dynamic property shifts can show …

Seismic modeling, analysis and design of structural concrete pile-deck connections
… the pile-deck interface, (ii) the evaluation of damage indices reported in the literature, for use in characterizing the ensuing nonlinear behavior, and (iii) a parametric study of structural interactions affecting pile-deck connections. Initially, a fiber-based computational model, comprising …

Performance of Full-Scale Reinforced Concrete Columns Subjected to Extreme Earthquake Loading
… bar and tie spacing are minor. The evolution of damage during application of the various loading protocols was quantified using several cumulative and noncumulative damage index models. In addition, observed visual damage to the specimens was used to assess calculated damage indices based on …

Post-Earthquake Damage Repair and Probabilistic Damage Control Approach for Reinforced Concrete Bridges
… reinforced polymers (CFRP) and probabilistic damage control approach (PDCA) for reinforced concrete (RC) bridges. To develop repair methods, first repair objectives were defined. To define repair objectives, internal earthquake damage was quantified and correlated to a series of visible damage …
