RISFast Kinematic Calibration of a Robotic Manipulator Through a Single Continuous Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The measurement step of the existing calibration approaches for robotic manipulators can take a considerable amount of time to settle a robotic manipulator down at certain static configurations, making the calibration ...
Experimental and Numerical Study on Rolling Friction in Tower Saddle of Suspension Bridges
Publisher: ASCE
Abstract: Rolling friction pairs in the tower saddle of suspension bridges could significantly reduce the horizontal load that is transferred to the tower. To investigate the dependence of the rolling friction coefficient (μ) of a ...
Which Temperature and Precipitation Extremes Best Explain the Variation of Warm versus Cold Years and Wet versus Dry Years?
Publisher: American Meteorological Society
Abstract: AbstractIntensifying climate extremes are one of the major concerns with climate change. Using 100-yr (1911?2010) daily temperature and precipitation records worldwide, 28 indices of extreme temperature and precipitation ...
Concrete Crack Assessment Using Digital Image Processing and 3D Scene Reconstruction
Publisher: American Society of Civil Engineers
Abstract: Traditional crack assessment methods for concrete structures are time consuming and produce subjective results. The development of a means for automated assessment employing digital image processing offers high potential ...
Experimental Study on Tensile Behavior of Wet Joints in a Prefabricated Composite Deck System Composed of Orthotropic Steel Deck and Ultrathin Reactive-Powder Concrete Layer
Publisher: American Society of Civil Engineers
Abstract: The widely used orthotropic steel deck system is subject to several durability problems: fatigue cracking of the steel, wearing of the surfacing, and corrosion. Thus, the composite deck system composed of an orthotropic ...
Modeling Techniques for Strain-Range-Dependent Hardening Behavior of Low-Yield-Point Steel Shear Panel Dampers
Publisher: American Society of Civil Engineers
Abstract: Shear panel dampers made of the low-yield-point steel exhibit significant overstrength under cyclic loading—a phenomenon that has been observed to depend not only on accumulated plastic deformations but also the loading ...
Seismic Performance of Joints between Steel K-Style Outrigger Trusses and Concrete Cores in Tall Buildings
Publisher: American Society of Civil Engineers
Abstract: This paper presents finite-element analysis (FEA) and experimental study on the seismic behavior of joints between steel K-style outrigger truss and concrete core in tall buildings. Two new joint types with different ...
Stress Increment of Unbonded Prestressing Tendons in Prestressed Concrete Girders with Corrugated Steel Webs
Publisher: American Society of Civil Engineers
Abstract: Experimental and finite-element studies have shown that a significant correlation exists between the stress increment of unbonded prestressing tendons and the flexural load of prestressed concrete girders with corrugated ...
Cable Anchorage System Modeling Methods for Self-Anchored Suspension Bridges with Steel Box Girders
Publisher: American Society of Civil Engineers
Abstract: The multiscale modeling method is newly introduced to the research on cable anchorage systems for self-anchored suspension bridges with steel box girders to improve the reliability of the conventional modeling methods. Two ...
Stability and Adequate Bracing Design of Pretensioned Cable-Braced Inverted-Y-Shaped Ferris Wheel Support System Using Matrix Structural Second-Order Analysis Approach
Publisher: American Society of Civil Engineers
Abstract: Elastic buckling and second-order analyses are conducted using the matrix structural analysis approach for the in-plane and out-of-plane stability and adequate bracing design of a new type of Ferris wheel support system ...
