Abstract: The radial, lateral, and tangential stiffness of spoked bicycle wheels depends upon the rim's bending inertia, torsional inertia, the spoke sizes, and the spoke geometry. The spokes of three rear bicycle wheels of different ...

Abstract: The responses of two, low-rise, 2-degree-of-freedom base isolated structures with different isolation periods to a set of near-field earthquake ground motions are investigated under passive linear and nonlinear viscous ...

Abstract: This paper describes a simulation method for the equivalent magnetic permeability of mangetorheological (MR) fluids considering cluster formation of suspended particles. The cluster formation under ...

Abstract: This paper evaluates momentless, or funicular, arches designed using Bernoulli-Euler beam theory and evaluates the errors associated with the Bernoulli-Euler and straight-beam approximations. When arches support hydrostatic ...

Abstract: Passive damping in shock and vibration isolation systems reduces the deformation of the isolation system but can increase the acceleration sustained by the isolated object. Semiactive (i.e., controllable) damping systems ...

Abstract: This paper presents statistical models for the generation of biaxial earthquake ground-motion time histories with spectra that match those from samples of ground-motion records. The model parameters define near-field ...

Abstract: Sets of ground-motion records used for seismic hazard analyses typically have intensity measures corresponding to a particular hazard level for a site (perhaps conditioned on a particular intensity value and hazard). In ...
