’Smart Bridge’ Technology Debuts in New Mexico

20.07.2004


The new Interstate 10 bridge over University Avenue in Las Cruces may look like any other highway bridge, but it isn’t.

Embedded deep within the bridge’s concrete beams are fiber-optic sensors that will allow engineers to continually monitor the safety of the bridge. The $6.3 million bridge is the first interstate highway bridge in the nation to be fitted with this type of “smart bridge” technology.

“Traditionally, bridge inspections have relied primarily on a visual inspection of the exterior of the bridge,” says Rola Idriss, a professor of civil engineering who is leading NMSU’s “smart bridge” research. “This monitoring system can provide information on the effects of stress long before signs of fatigue begin to show visibly, allowing engineers to address potential problems before they become serious and costly.”



Ultimately, Idriss says, the technology should lead to better bridge designs.

The sensors embedded in the four-lane bridge are made by a Swiss company called Smartec. One hundred and twenty sensors were embedded in each of the bridge’s six 90-ton beams when they were cast in Albuquerque, N.M., earlier this year.

Fiber-optic lines also were strung throughout the concrete to shoot beams of light through the structure. As the beams are stressed, the properties of the light change. These changes are picked up by the sensors and relayed to a data collection box about the size of a refrigerator that is located off the side of the bridge. NMSU researchers will collect the data from this box, study it, and share it with the New Mexico Department of Transportation.

NMSU received a $500,000 grant from the NMDOT and the Federal Highway Administration to cover the cost of purchasing the sensors, installing them, and monitoring the bridge for three years. Albuquerque Underground Inc. (AUI) was the contractor on the project.

The technology was tested in 2000 on a smaller bridge over the Rio Puerco west of Albuquerque. It was monitored for a year following construction, and proved to be a success.

Depending on the research results of the I-10 bridge over University Avenue, Idriss says that “smart bridge” technology might become standard in the construction of bridges in the future.

Idriss says the same technology could be applied to buildings in earthquake-prone areas to monitor unseen structural damage after earthquakes.

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
