FINITE ELEMENT METHOD (03209152)

Type of Course: M. Tech.

Prerequisite: Mechanics of Solids, Matrix Methods of Structural Analysis andStructural Analysis

Rationale:Complicated geometries, loadings, and material properties, analytical solutions generally require the solution of ordinary or partial differential equations, which are not usually obtainable. Hence, the structural engineers need to rely on numerical methods, such as the finite element method, finite difference method, and boundary element method etc., for acceptable solutions. Among thesenumerical methods, finite element method is such a widely accepted method that can be systematically programmed to accommodate complex and difficult problems.

STRUCTURAL DYNAMICS (03209152)


Prerequisite: Mathematics, Engineering Mechanics and Earthquake Engineering Rationale:Earthquakes impose time-dependant lateral inertia forceson the structure. To make a structure earthquake resistant, it is to be designed for lateral loads in additionto gravity loads. The lateral loads acting on structure are calculated using theory of structural dynamics.Therefore, the understanding of structural dynamics, characteristic of earthquakes and its effect onstructure is essential for safe design of civil engineering structures.
