Dynamic Response of Bridges and its Effect on Soil Medium
Abstract: The analysis of dynamic behaviour of bridge structures that are subjected to moving loads has been one of the research benefits in recent years. Specifically in railway bridges, resonance ensues when the load frequency is equal to a multiple of natural frequency of the structure. Resonance vibrations have been practical in railway bridges, especially subjected to high-speed lines. They are caused primarily because of two reasons: one is the repeated …

A Study on Method and Modelling of Structural Analysis and Finite Elements: A Review
Abstract: The finite element method (FEM) or finite element analysis (FEA), is a numerical method usually employed for solving engineering (structural mechanics) and mathematical physics problems. Generally, the analytical solution of these problems require the solution to boundary value problems for partial differential equations. Specimens are usually tested and analysed using finite element method (FEM) for investigating the behaviour of square concrete columns confined by fibre reinforced polymer (FRP) and sheets.

Finite Element Analysis of Rectangular Plate of S460J2 With Multiple Circular Holes
Abstract: Stress concentration is the main root cause of failure of multi-hole plates in bi-axial loaded conditions. Therefore it is essential to study such Stress Concentration Factors (SCF) to achieve the failure criteria. The method used for analysis is FE analysis. The main cause of increment in the stress is the geometrical irregularity, which may be caused by the various machining operations. Some kind of operations also requires such irregularity for …
