RISExperimental Study on Damage Assessment of Concrete T-beam Bridges
Publisher: American Society of Civil Engineers
Abstract: The effect of damaged transverse connection of diaphragm beams on the bearing capacity of prefabricated concrete T-beam bridges was studied through model experiment and finite element analysis. On the basis of standard ...
Determination of Optimal MR&R Policies for Retaining Life-Cycle Connectivity of Bridge Networks
Publisher: American Society of Civil Engineers
Abstract: Bridge management problems are computationally difficult to solve when considering network connectivity, because all bridges must be analyzed together. Past research has usually adopted simulation-based numerical methods, ...
Method for Generating Statically Determinate Cable Net Topology Configurations of Deployable Mesh Antennas
Publisher: American Society of Civil Engineers
Transient Growth and Receptivity of Steady Disturbances to Irregular Rough Walls
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Direct numerical simulations (DNS) are performed to investigate the transient growth of a steady disturbance induced by a numerically generated Gaussian rough wall in a laminar boundary layer. In the calculation of the ...
Thermal Non-Newtonian EHL Analysis of Rib-Roller End Contact in Tapered Roller Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An EHL approach to the rib-roller end contact in tapered roller bearings has been achieved by taking into account the non-Newtonian behavior of lubricants and thermal effects and with full ...
Influence of Proximity of the Seabed on Hydrodynamic Forces on a Submarine Piggyback Pipeline Under Wave Action
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental investigations were mainly carried out to clarify the influence of the seabed proximity on hydrodynamic forces on a submarine piggyback pipeline under regular and irregular wave action. Nondimensional force ...
Hydrodynamic Forces on a Large Pipeline and a Small Pipeline in Piggyback Configuration under Wave Action
Publisher: American Society of Civil Engineers
Abstract: Experiments on a large pipeline and a small pipeline in a piggyback configuration under regular and irregular waves are carried out. A comparison of the wave forces on the large pipeline and the small pipeline is made. The ...
Pore-Scale Simulation on Pool Boiling Heat Transfer and Bubble Dynamics in Open-Cell Metal Foam by Lattice Boltzmann Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Based on the newly developed geometrical model of open-cell metal foam, pool boiling heat transfer in open-cell metal foam, considering thermal responses of foam skeletons, is investigated by the phase-change lattice ...
Fault Diagnosis for Road Heading Bearings Based on a Multiscale Enhanced Cascaded Difference Filter
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a novel multiscale morphological filter (MMF), called multiscale enhanced cascaded difference filter (MECDF), is proposed for the fault detection of road heading bearings. First, the cascaded morphological ...
Synthetic-to-Real Domain Adaptation with Virtual Laser Scanning and Self-Training–Based Category-Aware Cuboid Mixing for Semantic Segmentation of Bridge Point Clouds
Publisher: American Society of Civil Engineers
Abstract: AbstractA scarcity of real-world point clouds poses a considerable challenge in training a
bridge semantic segmentation model. Although virtual point cloud synthetization offers
a promising alternative, the persistent ...
