Abstract: A piezoceramic (PZT) patch can be used simultaneously as an actuator and as a sensor for structural damage detection by utilizing its electromechanical coupling property. In this technique, a PZT actuator-sensor patch is ...

Abstract: The Trans-Tokyo Bay Highway Crossing, completed in 1997, is 11 km in total length and is a combined tunnel and multiple bridge route that includes a ten-span continuous steel box-girder bridge with a total length of 1,630 ...

Abstract: The performance of a damper in controlling large-amplitude vibrations of a stay cable in a bridge is influenced by essential parameters such as the amount of sag and flexural rigidity of the cable, and the stiffness of the ...

Abstract: The combined effect of two dampers, either on the same end or opposite ends of a stay cable, is analytically studied in this paper. By considering small distances of the dampers from the anchorages, an asymptotic formula ...

Abstract: This paper presents a method for computing the response of a 1D elastic continuum induced by a multi-degree-of-freedom (MDOF) oscillator traveling over it. The continuum and the oscillator are nonconservative systems with ...

Abstract: Auto-parametric vibration of a cable-stayed-beam structure under a random excitation is first studied numerically with emphasis on cable local vibration. A simplified 3-degree-of-freedom model that includes linear as well ...

Abstract: The effects of bending on the modal properties of a stay cable with a transverse damper are analytically studied. Considering that the value of the flexural rigidity in the stay cable is small in practice, an explicit ...

Abstract: Active control for small-sag cable using the axial support motion is developed. The nonlinear motion of the cable with moving support is expressed as a bilinear system in which the product of the axial support motion and ...

Abstract: Modern footbridges are often characterized by architectural demands for light, slender, and long structures that may lead to excessive vibration problems. In past decades, occurrences of pedestrian-induced vibration on ...
