Moving Load Analysis on Skewed Railway Bridge

Recent developments in the field of high speed rail have heightened the need for improving of railway bridges under the passage of high speed trains. However, little attention has been paid to influence of significant parameters playing a key role in dynamic behavior of such bridges. This paper seeks to fill such a gap by carrying out finite element (FE) analysis on an existing railway bridge. ...

Seismic Vulnerability assessment of concrete railway bridge using nonlinear analyses

Bridges, as an essential part of transportation system, play a special role in economy, politic and military all around the world. Serviceability of bridges is of high importance especially in emergencies, helping injured people and proportioning transportation after earthquakes. Earthquake regulation codes, normally suggest linear methods to conduct the analysis, and nonlinear analysis is bare...

On Nonlinear Oscillations in a Suspension Bridge System

In this paper, we study nonlinear oscillations in a suspension bridge system governed by two coupled nonlinear partial differential equations. By applying the Leray-Schauder degree theory, it is proved that the suspension bridge system has at least two solutions, one is a near-equilibrium oscillation, and the other is a large amplitude oscillation.

Observations on the Motility of Rabbit Spermatozoa in Dilute Suspension

1. Rabbit spermatozoa suspended in Baker's solution rapidly lose motility at relatively high dilutions. At a concentration of 0.4 million per ml., the spermatozoa from most ejaculates are completely immotile within 2 or 3 hours. The same phenomenon occurs with chloride-free diluents and is therefore not due to the toxic action of chlorides. 2. This rapid immobilisation may be prevented by suspe...

Smart Suspension Systems for Bridge-Friendly Vehicles

In this paper, the effects of using semi-active control strategy (such as MR dampers) in vehicle suspensions on the coupled vibrations of a vehicle traversing a bridge are examined in order to develop various designs of smart suspension systems for bridge-friendly vehicles. The bridge-vehicle coupled system is modeled as a simply supported beam traversed by a two-degree-of-freedom quarter-car m...
