RISBehavior of Perforated Shear Connectors in Steel–Concrete Composite Joints of Hybrid Bridges
Publisher: American Society of Civil Engineers
Abstract: Perforated shear connectors (PSCs) in steel–concrete composite joints are usually deeply embedded in concrete, and the perforated plate thickness varies significantly, which is different from those in a steel–concrete ...
Surface Albedo over the Arctic Ocean Derived from AVHRR and Its Validation with SHEBA Data
Publisher: American Meteorological Society
Abstract: A method is presented for retrieving the broadband albedo over the Arctic Ocean using advanced very high resolution radiometer (AVHRR) data obtained from NOAA polar-orbiting satellites. Visible and near-infrared albedos ...
Semianalytical Method for Controlling the Deformation of Retaining Structures Subjected to Asymmetrical Loads
Publisher: ASCE
Abstract: In excavation engineering, most of the retaining structures are subjected to asymmetrical loads, including in asymmetrical excavation and asymmetrical overloading. However, a theoretical solution to, and deformation-controlling ...
Vehicle-Induced Lateral Vibration of Railway Bridges: An Analytical-Solution Approach
Publisher: American Society of Civil Engineers
Abstract: The lateral vibration of railway bridges induced by moving trains has traditionally been solved through numerical integration. Although it provides practical prediction, the numerical approach does not explicitly reveal ...
Effects of Earthquake-Induced Hydrodynamic Force on Train–Bridge Interactions
Publisher: ASCE
Abstract: High-speed trains running over sea-crossing railway bridges can be subjected to earthquake action in deepwater. In analyzing hydrodynamic-induced response on train–bridge interactions, the effect of earthquake-induced ...
Numerical Study of the Seismic Responses of Precast Segmental Column Bridge under Spatially Varying Ground Motions
Publisher: American Society of Civil Engineers
Abstract: Compared with traditional monolithic columns, precast segmental columns can significantly reduce the residual displacement after a severe earthquake. Previous studies of precast segmental columns mainly focus on the column ...
A Critical Examination of Satellite Cloud Retrieval from AVHRR in the Arctic Using SHEBA Data
Publisher: American Meteorological Society
Abstract: This study examines the validity and limitations associated with retrieval of cloud optical depth τ and effective droplet size re in the Arctic from Advanced Very High Resolution Radiometer (AVHRR) channels 2 (0.725?1.10 ...
Modeling Noise Radiation From Concrete Box Girder Bridges as an Infinitely Long Periodic Structure Excited by a High-Speed Train
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Concrete box girder bridges occupy over 80% of the total mileage of the Chinese high-speed railway. The box girder structure has many natural modes of low frequencies, which can be excited by a train passing at high-speed, ...
Effects of Nonuniform Crosswinds in Valleys on Dynamic Responses of High-Speed Trains and Long-Span Suspension Bridges
Publisher: ASCE
Abstract: This study examined the influence of nonuniform wind fields in valleys on the dynamic responses of high-speed trains and long-span bridges. The wind field in a valley is considerably different from a theoretical uniform ...
Numerical Investigation on Instability of Buildings Caused by Adjacent Deep Excavation
Publisher: ASCE
Abstract: The embedded ratio of retaining structures and improved depth of ground at an excavation base are two key factors for the stability of deep excavation. For a collapsed excavation in soft clay in Hangzhou, China, a numerical ...
