Bridges are an important component of transportation. Flutter is a self-excited, large amplitude vibration, which may lead to collapse of bridges. It must be understood and avoided. This paper takes the Jianghai Channel Bridge, which is a significant part of the Hong Kong-Zhuhai-Macao Bridge, as an example to investigate the flutter of the bridge deck. Firstly, aerodynamic force models for flut...

The results of an experimental investigation of kerbside bridge deck drainage units are presented. The conveyance capacity, resistance coefficients and sediment transporting efficiencies of different types of drainage unit used in shallow bridge drainage decks are examined over a range of bed gradients likely to be encountered in practice. The use of a V-shaped cross section is shown to be part...

Most of the work on card shuffling assumes that all the cards in a deck are distinct, and that in a well-shuffled deck all orderings need to be equally likely. We consider the case of decks with repeated cards and decks which are dealt into hands, as in bridge and poker. We derive asymptotic formulas for the randomness of the resulting games. Results include the influence of where a poker deck ...

A time domain method is presented to identify the moving loads on the bridge deck from measuring strains. The bridge deck is modelled as a rectangular orthotropic plate. The vehicle is modelled as two axle loads moving on the bridge deck. Like all inverse problems, the identification is an ill-posed problem, so a regularization technique is employed to stabilize the solution. This paper gives a...

In present study, a mathematical model of the vehicle–floating slab track (FST) interaction is established to investigate the coupled behaviour of vehicle–track system. The FST is modelled as the double Euler -Bernoulli beam including the rail and slab. The railway vehicle is simplified as a multi-rigid-body model. The wheel–rail interface is treated using a nonlinear Hertzian contact model, co...

In this study, the flexural performance of a new composite beam–slab system filled with concrete material was investigated, where mainly prepared from lightweight cold-formed steel sections beam and deck slab for carrying heavy floor loads as another concept conventional lower cost impact. For purpose, seven samples profile sheet–dry board (PSSDB/PDS) carried by C-purlins (CB) were named “compo...
