Smart bridge sensors
The project is designed to showcase the future of smart, sustainable, user-centered transportation infrastructure that helps to monitor structural and environmental health.
Factors Leading to Concrete Bridge Cracks
When the current infrastructure was built in the 1950s, it was constructed for that era's traffic demands, with little focus on maintenance.
Flexible Materials Help Keep Bridges Open in a Big Quake
Bridge columns built using memory-retaining nickel/titanium rods and a flexible concrete composite returned to their original shape after a 7.5-magnitude tremor.
More Infrastructure Failures Likely as U.S. Assets Age
Fitch says in its 2016 Water and Sewer Medians report that capital spending dropped to the lowest level the agency has observed since publishing its annual medians.
Ultrasonic Technology Diagnoses Bridge Repair
Cement suspensions will be injected into the damaged areas of the arched bridge in such a way as to preserve the original appearance of an historic viaduct.
Robots Help to Build Modular Bridge
Robots may reduce health and safety risks by removing manual lifting and handling, while enhancing the quality of the weld, helping to ensure consistency and increasing output.
Bad Roads Can Cost You Money
Driving on poor roads increases consumer costs by accelerating vehicle deterioration and depreciation, increasing the frequency of required maintenance and boosting fuel consumption.
Electricity Used to Track Water, Identify Concrete Degradation
The technology can determine where and whether water is infiltrating concrete, as well as how fast it is moving, how much water there is and how existing cracks are influencing the water movement.
Photos Used to Catalog Building Damage
The researchers have to train the algorithms to recognize scenes and locate objects in the images.
Could Bacteria Create Building Foundations?
Researchers are modifying E. coli bacteria to create a "gene circuit" that would enable the bacteria to respond to their environment by producing biocements.
Mass Plywood Panel to Compete in Timber Market
Mass plywood panel is a large-scale panel designed to be an alternative to cross-laminated timber.
"Sensing Skin" Detects Damage in Structures
The skin consists of three layers, which can be painted onto the surface of a structure or pre-assembled and attached like wallpaper.
Sea-Source Heat Pump Warms Buildings
The sea-source heating system comprises coils of pipes fixed to 12 stainless steel platforms known as "pond mats" that are sunk beneath a nearby pier and draw heat from the surrounding water.
Snow Could Reduce Air Conditioning Load
Directing a building’s air-handling units through snow collected and stored from winter road-clearing operations can reduce the need to use air conditioning during warmer parts of the year.
Little to Protect Persian Gulf Construction Workers
Nearly all the workers come from other countries, drawn by plentiful work in recent years due to the fast pace, high volume and large scale of construction on some of the world’s tallest skyscrapers.
Wave Splash Model Could Improve Seawall Design
Use of the model could help inform the design of seawalls that, until now, have not taken into account the pattern of spray produced by waves.
Data Centers Cause Buildings' Electricity Use to Spiral
Cooling electricity intensity in buildings with data centers was found to be almost double that of other buildings in both the smallest and largest categories of office buildings surveyed.
Simplified Solution for Offshore Wind Turbine Installation?
The offshore wind turbine system can be pre-assembled onshore and towed to its final site.
New York Bridge, Tunnel Upgrades Planned
Tunnels will be hardened to withstand a 500-year flood, with water-tight barriers installed to block floodwaters from entering.
