Course Objectives

• To understand the basic principles of structural mechanics so that it forms the basis for study of structure systems.

Learning Objectives

To understand the structural concept, applications feasibilities, scope and limitations of RCC and Steel Structures. (No detailed designs mathematical calculations or derivation of formulae are needed.)

Masonry Arches, Masonry Vaults & Masonry Domes: Conceptual study as compression structures. (Without design calculations). General understanding of Arch and Dome behaviour and terminology, Historical perspective, Types of domes: Single shell and Double shell domes, Cylindrical, Conical, Spherical domes, Hyperbolic and paraboloid shells. Stresses in domes; Use of Arch and dome structures in Industrial structures and overhead water tanks. Modern day use of Arch and Dome structures.

Tensile Structures : Principles of tensile structures, understanding general structural behaviour of tension systems, calculating sag and cross sectional area of cables, cable suspended and cabled-stayed structure, examples of modern day use.

Introduction to Pre-stressing: Principles of Pre-stressing, Pre and Post tensioning, approximate calculations of pre-stressing force, examples of modern day use Prefab and Industrial structures.

Pedagogy          

·        The lectures by the experts in the field will be arranged for the students so as to give them exposure to the practical aspects construction materials and how they combine to cover space.

·        The emphasis should be given to actual working on materials, making of models and studying their behavior under forces / loads.

·        To prepare the students to use their data/knowledge gained in the subject for practical application.

·        Groups of four to five students should be formed to study the behavior of a materials and their use and to prepare the report on the same.

·        The students should preferably be made to co-ordinate the fabrication of models to demonstrate the behavior of materials and how different components of   structure combine to cover space.
