Structural analysis of the deck of access bridges in offshore docks under dynamic loading of moving heavy vehicles (Case study: 10 feet concrete deck with prefabricated beam, under the passage of 125-ton bogie)
Ports are the most important economic, political and military bottlenecks. This puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. Pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. Correct and exact estimation of...
متن کاملResearch on Moving Force Estimation of the Bridge Structure using the Adaptive Input Estimation Method
The vehicle/bridge interaction moving forces are important for the bridge structure design and the reliability evaluation. Therefore, the dynamic moving forces produced by the vehicles on the bridge structure must be determined by adopting the estimation method or measurement techniques. Direct measurement of the vehicle moving forces using sensors with higher precision is expensive and is subj...
متن کاملIdentification of Moving Loads on a Rectangular Orthotropic Plate from Strains
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...
متن کاملVibration and Stability of Axially Moving Plates by Standard and Spectral Finite Element Methods
Based on classical plate theory, standard and spectral finite element methods are extended for vibration and dynamic stability of axially moving thin plates subjected to in-plane forces. The formulation of the standard method earned through Hamilton’s principle is independent of element type. But for solving numerical examples, an isoparametric quadrilateral element is developed using Lagrange ...
