A simple beam element is developed for the solution of large deflection problems. The total Lagrangian formulation is based on the kinematic relations proposed by Reissner for finite rotations and stretching as well as shearing of plane beams. The motion is discretized by linear expansions of the ...
N} as described in Equation (2.52). In the first iteration, the noise correlation matrix will be simply σ2I (or σ2R0 for SPM). After the last iteration, all the time delays for which a signal was detected are tabulated and the earliest delay is chosen as the first TOA of the ...
This article provides a state-of-the-art review on the design and construction of the standard simply-supported beam (simple beam) bridges for high-speed rails in China. The structural components discussed include the main girder, deck, and substructure. The live load models, deformation limiting...
