RISShear Lag Effects in Reinforced Concrete C-Shaped Walls
Publisher: American Society of Civil Engineers
Abstract: Shear lag effects can significantly reduce the moment capacity of nonrectangular reinforced concrete walls. Although this phenomenon is recognized as an important component in the analysis and design of buildings, it is ...
Decay of Torsional Stiffness in RC U-Shaped Walls
Publisher: ASCE
Abstract: Reinforced concrete (RC) U-shaped walls are a popular construction choice, commonly used to resist the lateral loads from wind and earthquakes. In many buildings, the center of stiffness of a floor is eccentric from the ...
Field Monitoring of RC-Structures under Dynamic Loading Using Distributed Fiber-Optic Sensors
Publisher: ASCE
Abstract: The ability to properly assess existing reinforced concrete (RC) structures provides an opportunity to prevent costly rehabilitations or replacements and aid in the optimization of future designs. Distributed fiber-optic ...
Lessons from Flipping Subjects in Engineering: Effectiveness of Student Learning in a Flipped Environment at the University Level
Publisher: ASCE
Abstract: This paper outlines the subjective and quantitative outcomes of the introduction of the flipped classroom approach to two engineering subjects at the University of Melbourne. In this approach, lectures are delivered online ...
Development of an Axial Strain Measurement System for Rails
Publisher: ASCE
Abstract: Train derailments caused by buckled or broken rail continue to be both a safety and economic concern for North America’s railway industry. These track failures are often attributed to excessive axial stresses in continuous ...
Flexure–Torsion Response of Compressed Open Reinforced-Concrete Cores: Experimental Strain Gradients, Numerical Methods, and Interaction Diagrams
Publisher: American Society of Civil Engineers
Abstract: Together with axial and flexural actions, modern-designed reinforced-concrete walls can also be subjected to torsion during rare loading events, such as large-magnitude earthquakes or strong winds. For certain widely used ...
Soot Formation in a Turbulent Swirl Stabilized Laboratory Combustor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effect of pressure and fuel composition on soot formation was studied using a high pressure, tubular laboratory burner with a swirl stabilized diffusion flame. A specially-designed water ...
Distributed Strain Behavior of a Reinforced Concrete Bridge: Case Study
Publisher: American Society of Civil Engineers
Abstract: To effectively assess and manage aging infrastructure, sensing technologies that produce accurate and useful quantitative data are required. Distributed fiber optic strain measurement systems are one potential technology ...
Methanol as a Soot Reducer in a Turbulent Swirling Burner
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The combined effect of using methanol as a fuel additive together with a prototype multifuel injector has been evaluated with regard to soot formation in a tubular laboratory burner with a ...
Time-Dependent Behavior of RC Beams Retrofitted with CFRP Straps
Publisher: American Society of Civil Engineers
Abstract: A retrofitting technique that uses prestressed unbonded carbon-fiber-reinforced polymer (CFRP) straps to provide additional shear capacity has previously been shown to be successful under short-term static loading conditions. ...
