Nonlinear Time History Analysis of Anti Seismic Device on Highway Bridges
International Journal of Advances in Scientific Research and Engineering, 2020 There are many earthquake suppression technologies offered by experts, one of them is the use of Lead Rubber Bearing (LRB) in civil buildings. LRB works by reducing the dynamic load acting on a bridge caused by seismic loads. It diverts the load that works through the dynamic system by maintaining a balance between the force and displacement that ...

Properties and stability of freely propagating nonlinear density waves in accretion disks [PDF]
, 2007 In this paper, we study the propagation and stability of nonlinear sound waves in accretion disks. Using the shearing box approximation, we derive the form of these waves using a semi-analytic approach and go on to study their stability.
