Finite Element Analysis
Finite Element Analysis (FEA) is a method of analysing the behaviour of structures and systems under various loading conditions. It is used to predict the performance of a structure, evaluate its safety, and optimise its design.
In structural engineering, FEA involves creating a computer model of the structure using a mesh of interconnected elements. Each element represents a portion of the structure, and the properties of each element, such as its material properties and geometry, are defined. The elements are then assembled into a system of equations, which is solved numerically to determine the response of the structure under specific loads.
FEA can be used to analyse a wide range of structural engineering problems, including static and dynamic loads, linear and nonlinear material behaviour, and complex geometries. It can also be used to simulate the behaviour of structures under extreme conditions, such as earthquakes or high winds.
FEA allows engineers to test various design scenarios, evaluate the impact of different loads and boundary conditions, and optimise the structure’s performance. By simulating the behaviour of a structure before it is built, engineers can identify potential issues and make informed design decisions that reduce costs and improve safety.
Why choose Neilly Davies?
The accuracy of FEA results depends on the quality of the input data and assumptions made during the modelling process. The structural engineering team at Neilly Davies has extensive experience in the numerical methods and engineering principals required to accurately perform FEA. Using SAP2000 and ETABS, the structural engineering team has performed calculations for static, dynamic, linear and nonlinear structural systems to ensure that the building or structure is safe for occupants and the surrounding environment.
