Evaluation And Damage Detection Of Highway Bridges With Distinct Vulnerabilities, Mohammad Abedin

FIU Electronic Theses and Dissertations

Bridge failures over the past few decades have shown conventional bridge monitoring is insufficient to effectively evaluate the safety of this important piece of infrastructure. Therefore, new methods for bridge monitoring and special considerations in bridge design are needed to ensure the health of these structures as they continue to age and prevent the possibility of catastrophic collapses. The objective of this research is to explore new means for detecting damage in bridge members during normal operations that are both accurate and affordable at the same time. However, to make any damage detection method effective and efficient, the behavior of …

Extending Use Of Simple For Dead Load And Continuous For Live Load (Sdcl) Steel Bridge System To Seismic Areas, Ramin Taghinezhadbilondy

FIU Electronic Theses and Dissertations

The steel bridge system referred to as Simple for Dead load and Continuous for Live load (SDCL) has gained popularity in non-seismic areas of the country. Accordingly, it results in many advantages including enhanced service life and lower inspection and maintenance costs as compared to conventional steel systems. To-date, no research studies have been carried out to evaluate the behavior of the SDCL steel bridge system in seismic areas. The main objective of this research was to extend the application of SDCL to seismic areas.

The concept of the SDCL system was developed at the University of Nebraska-Lincoln and a …
