RISReal-Time Monitoring of Early-Age Concrete Strength Using Piezoceramic-Based Smart Aggregates
Publisher: American Society of Civil Engineers
Abstract: It is well known that concrete is the most common type of structural material, and a proper estimation of concrete strength in its early age can provide guidance for staged concrete construction and ensure the load-bearing ...
New Type of Pounding Tuned Mass Damper for Confined Space
Publisher: ASCE
Abstract: Due to their construction features, many structures have confined spaces, such as the hollow tube of a wind turbine tower and the tube members of large-span space structures. To meet the requirement of aesthetics, the ...
Temperature Sensing and Hydration Study of Carbon Nanofiber Aggregates
Publisher: ASCE
Abstract: Fiber research in concrete construction technology has been helping to prevent catastrophic disasters due to the loss of structural integrity and service life by functioning as structural health monitoring (SHM) technology. ...
Two-Dimensional Deformation Estimation of Beam-Like Structures Using Inverse Finite-Element Method: Theoretical Study and Experimental Validation
Publisher: ASCE
Abstract: The real-time estimation of structural deformations using discrete strain data, known as shape sensing, is critical to the health monitoring of structures such as bridges. An innovative methodology called the inverse ...
Investigation of Locking Force for Stay Cable Vibration Control Using Magnetorheological Fluid Damper
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The locking force of stay cable vibration control using a magnetorheological (MR) fluid damper is investigated in this paper. For a single mode vibration of a stay cable equipped with a MR ...
Automatic Controls for the Carbon Fiber Tape-Based Deicing Technology
Publisher: American Society of Civil Engineers
Abstract: Snow and ice on roads are hazardous. Many methods are applied for road surface deicing. Most of these methods, however, suffer from one or more of the following shortcomings: low energy efficiency, large labor requirements, ...
Numerical Assessment of Electric Roadway Deicing System Utilizing Emerging Carbon Nanofiber Paper
Publisher: American Society of Civil Engineers
Abstract: Traditional deicing approaches such as salting pollute the environment and corrode reinforcing steel bars in concrete. Meanwhile, recently emerging carbon nanofiber material has improved electrical conductivity, a large ...
Monitoring the Soil Freeze-Thaw Process Using Piezoceramic-Based Smart Aggregate
Publisher: American Society of Civil Engineers
Abstract: Monitoring the soil freeze-thaw process is of great importance to engineering design of infrastructure, observation of hydrology, variation of climate, and existence of vegetation in cold regions. This paper presents ...
Scour Monitoring System Using Fiber Bragg Grating Sensors and Water-Swellable Polymers
Publisher: American Society of Civil Engineers
Abstract: Bridge scour has emerged as a significant concern worldwide, especially in the United States; approximately 60% of bridge failures are scour related. Because of the difficulty of bridge-scour inspection, scour-induced ...
Experimental Study on Carbon Fiber Tape–Based Deicing Technology
Publisher: American Society of Civil Engineers
Abstract: In cold regions, snow and ice cause serious safety problems to the transportation system. South central Alaska, particularly Anchorage, is susceptible to a number of icing events resulting from frequent freeze/thaw cycles ...
