Maintaining bridges is pricey. There are 600,000 of them within the US, and the organizations that personal and preserve them can simply pay $50,000 for sensor gear alone, with additional prices incurred by the necessity to preserve them and analyze the information they generate. Smartphones are a less expensive possibility.
However, work nonetheless must be carried out to make this method a actuality, says Ahmet Emin Aktan, a professor of civil, architectural, and environmental engineering at Drexel University, who was not concerned within the research. He believes it’ll be a very long time earlier than the method turns into broadly adopted.
Aktan expects visible inspections to stay the first technique of monitoring bridges for the subsequent 10 to twenty years, as a result of each sensors and smartphones can produce information that’s tougher to interpret than what engineers see with their very own eyes. Even one thing as strange as climate or variations in site visitors load can have an effect on the way in which buildings behave and transfer, which may then have an effect on the information. For instance, they change into stiffer in colder climate.
But ultimately, he says, it’s probably that the business will wish to use a mixture of that visible commentary with the information collected from smartphones.
