Ambient Vibration Test on Reinforced Concrete Bridges

The Non-Destructive Test of Steel Corrosion in Reinforced Concrete Bridges Using a Micro-Magnetic Sensor

This paper presents a non-destructive test method for steel corrosion in reinforced concrete bridges by using a 3-dimensional digital micro-magnetic sensor to detect and analyze the self-magnetic field leakage from corroded reinforced concrete. The setup of the magnetic scanning device and the measurement mode of the micro-magnetic sensor are introduced. The numerical analysis model is also bui...

Steel versus Steel-reinforced Concrete Bridges: Environmental Assessment

Bridge material selection has traditionally been b~ed on e.ngineering and economi~ criteria. With the increasing interest of the public, industry, and government m sustainable:: development, en~lronmental. assessment in construction is becoming more important. However, we need metrtcs and data on deSign alternatives for effective decision making. In this paper, we present results of a life cycl...

Tapered Polymer Fiber Sensors for Reinforced Concrete Beam Vibration Detection

In this study, tapered polymer fiber sensors (TPFSs) have been employed to detect the vibration of a reinforced concrete beam (RC beam). The sensing principle was based on transmission modes theory. The natural frequency of an RC beam was theoretically analyzed. Experiments were carried out with sensors mounted on the surface or embedded in the RC beam. Vibration detection results agreed well w...
