RISA Further Discussion on the Singularity of Driving-Point Receptance in Structural Dynamics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Driving-point receptance of a structure, defined as the displacement amplitude of the structure at the same point and in the same direction as a unit point harmonic force causing the displacement, is a well-established ...
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, ...
