Predicting the Dynamic Response of Friction Dissipative Foundations Using a Modified Newmark Model

, 2016
This paper analyses the dynamic behaviour of a seismic isolation technology adopted for the foundations of the towers of two recent long-span bridges, consisting of a dissipative layer of granular soil placed at the contact of the foundation caisson with

Dynamic Response of Prestressed Tapered Timoshenko Beams to Uniform Partially Distributed Moving Loads

Academy Journal of Science and Engineering, 2022
The dynamics of a prestressed variable cross-section Timoshenko beam subjected to a moving partially distributed load is investigated. The Finite element method with Lagrange interpolation functions and reduced integration element were used to model the ...

Analysis of active vibration control of multi-degree-of-freedom flexible systems by Newmark method

, 2016
A flexible robot arm can be modeled as a lumped-parameter multi-degree-of-freedom mass spring system. The actuator at one end positions the payload at the other end. The flexibility causes the vibration of the payload at the end point.
