RISContinuous Approximation of Deficit Functions for Fleet Size Calculation
Publisher: ASCE
Abstract: It is a fundamental and important task to determine the minimum fleet size required for a public transit (PT) system because the fleet cost is a major operating expense experienced by PT agencies. More importantly, the ...
Shear Performance Evaluation of Reinforced Concrete Piers Subjected to Vehicle Collision
Publisher: ASCE
Abstract: In this study, finite element (FE) simulation is conducted to analyze the dynamic response and damage/failure characteristics of typical three-column reinforced concrete (RC) piers under vehicle collision, taking into ...
Theoretical Design and Dynamic Analysis of a Quasi-Zero Stiffness Device Using Precompressed Springs as Negative Stiffness Component
Publisher: ASCE
Abstract: Based on the principle of parallel connection of positive and negative stiffness structures, a new quasizero stiffness (QZS) isolation device is proposed in which the negative stiffness structure is designed by a nonlinear ...
Adaptive Synchronization Control of Multiple Spacecraft Formation Flying
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An adaptive nonlinear synchronization control approach is developed for multiple spacecraft formation flying with elliptical reference orbits. It can guarantee that both the tracking errors and ...
Imitation Control for Biped Robot Using Wearable Motion Sensor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In conventional imitation control, optical tracking devices have been widely adopted to capture human motion and control robots in a laboratory environment. Wearable sensors are attracting extensive ...
Measurement of Soft Tissue Deformation to Improve the Accuracy of a Body-Mounted Motion Sensor
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Skin deformation caused by muscle motion is a common source of error for body-mounted sensors. A new method of measuring joint angles using a combination of two-axial accelerometers and reaction ...
Experimental Investigation on Seismic Retrofitting of Square RC Columns by Carbon FRP Sheet Confinement Combined with Transverse Short Glass FRP Bars in Bored Holes
Publisher: American Society of Civil Engineers
Abstract: Jacketing is less effective to large square/rectangular RC columns due to the inability of the rectangular-shaped jacket in restraining the dilation of concrete in the middle of a straight side. A new retrofit method is ...
Health Monitoring System Developed for Tianjin 117 High-Rise Building
Publisher: American Society of Civil Engineers
Abstract: Tianjin 117 is a high-rise building comprised of a reinforced-concrete core and perimeter steel framing that includes megacolumns and megabraces, with a height of 597 m. As the construction process goes on, the influences ...
Strain Monitoring on PHC Pipe Piles Based on Fiber Bragg Grating Sensors
Publisher: American Society of Civil Engineers
Abstract: Fiber Bragg grating (FBG) sensors emerged as a relatively new strain-sensing technology for civil engineering applications. This study presents a field test to assess the feasibility of FBG sensors in monitoring the strain ...
Estimation of Active Earth Pressure on Inclined Retaining Wall Based on Simplified Principal Stress Trajectory Method
Publisher: American Society of Civil Engineers
Abstract: Because of the existence of wall-soil friction behind retaining wall, the transfer direction of the principal stress will be inevitably changed. Therefore, the arching effect of soil mass is considered and the circle ...
