Unit 1

Force and Displacement measurement – generalized or independent measurements – constrained or dependent measurements – n dimensional space – principle of superposition – methods of structural analysis. Structure with single and two coordinates – flexibility and stiffness matrices in n coordinates – examples – symmetric nature – constrained measurements – stiffness and flexibility matrices of the element as well as the system – computing the influence coefficient. Strain energy in terms of stiffness and flexibility matrices – interpretation of coefficient – Betti’s law – other energy theorems using matrix notation.

Unit 2

Flexibility and Stiffness Methods (Element Approach): Choice of redundant – ill and well condition equation – Transformation Matrices – transformation of one set redundant to other set – thermal expansion – lack of fit – application to pin-jointed plane truss – continuous beams, frames and grids. Development of stiffness method – analogy between flexibility and stiffness – analysis due to thermal expansion, lack of fit – Stiffness matrix with rigid body motion – application to pin jointed plane and space trusses – continuous beams – frames and grids – static condensation techniques. Problem solving by computer – choice of the method.

Unit 3

Introduction to Finite Element Method: Basic concepts – Rayleigh-Ritz Method – Finite difference method – Variational principles – MWR (theory only) – Steps in finite element method – Axial element force formulation by displacement method only – Theory of stress model -Displacement model – Hybrid models. Analysis and Design of Pin-jointed and Rigid-jointed Framed Structures using STADD pro (2D and 3D), Introduction to SAP, ETABS, ABAQUS.
