RISSystem Fragility Assessment of Tall-Pier Bridges Subjected to Near-Fault Ground Motions
Publisher: ASCE
Abstract: Numerous bridges with piers over 40 m are constructed in Southwest China, which is known as a region of high seismicity. In current research, this type of bridge is commonly simplified as a single-column system, and ...
Quasi-Biweekly Oscillation over the South China Sea in Late Summer: Propagation Dynamics and Energetics
Publisher: American Meteorological Society
Abstract: AbstractThe propagation dynamics and energetics of the quasi-biweekly oscillation (QBWO) over the South China Sea (SCS) in late summer [August?September (AS)] are investigated in this study. The QBWO originates from east ...
Analytical Acoustic Power Spectrum Formulations for Rotating Monopole and Dipole Point Sources
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analytical acoustic power spectrum formulations for the rotating monopole and dipole point sources are proposed by employing the spherical harmonic series expansion method. Both the analytical acoustic power spectra and ...
Moisture Absorption and Diffusion Characterization of Molding Compound
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The moisture absorption experiments of two kinds of molding compound are conducted. The diffusion at low temperature and humidity observes the Fick’s Law, but it does not strictly obey at ...
Reliability of High-Power Light Emitting Diode Attached With Different Thermal Interface Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: As a solid electroluminescent source, white light emitting diode (LED) has entered a practical stage and become an alternative to replace incandescent and fluorescent light sources. However, due ...
Ratcheting Study of Pressurized Elbows Subjected to Reversed In-Plane Bending
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With a multi-axial test machine, ratcheting was studied experimentally for pressurized low carbon steel elbows under reversed bending. The maximum ratcheting strain occurred mainly in the hoop ...
Fatigue Behavior of the Group Stud Shear Connectors in Steel-Concrete Composite Bridges
Publisher: American Society of Civil Engineers
Abstract: Clustering stud shear connectors with a narrow spacing to form the group studs is useful for concrete slab prefabrication in steel-concrete composite bridges; however, the group studs fatigue design has not been specified ...
Full-Scale Experimental Study on the Negative Flexural Behavior of Orthotropic Steel–Concrete Composite Bridge Deck
Publisher: American Society of Civil Engineers
Abstract: The orthotropic steel–concrete composite deck, which consists of a concrete slab, an orthotropic steel plate, and shear connectors, has been applied for ameliorating the vehicle-induced fatigue damage on steel bridge decks. ...
Rub-Impact Dynamics of Offset Disc Rotor with Imbalance and Loosening Pedestal
Publisher: ASCE
Abstract: It is easy for rotating machinery to produce looseness at the pedestal after long-term operation. The looseness of the pedestal causes the sudden increase of the vibration for the rotor, which leads to the rub-impact between ...
A Simple Model for Stable Cyclic Stress-Strain Relationship of Type 304 Stainless Steel Under Nonproportional Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a simple two-surface model for cyclic incremental plasticity based on combined Mroz and Ziegler kinematic hardening rules under nonproportional loading. The model has only ...
