3. Materials used in Masonry structures and there properties
4. Structural Members in Masonry Structures.
5. Types of Masonry Structures.

Timber

1. Types Of Timber

Unit 5: Structure Design Of Masonary And Timber Structures

Introduction: Characteristics of load bearing masonry structures, their merits, demerits and limitations vis a vis RCC framed structures. Classification of bricks and mortars according to strength. Allowable stresses in masonry; effects of slenderness ratio, area and shape factors on allowable stresses.

Design of Simple two storeyed House in load bearing masonry construction: Load calculations on slabs, transfer of load from slabs to load bearing masonry supporting walls. Design of load bearing masonry walls. Design of simple spread footings and retaining walls  for load bearing masonry walls.

Timber Structures: Structural timbers available in India, Structural properties and their allowable stresses, Design of timber Beams. (Simple M/Z application and shear check for forces along the grains (no slopes) Design of timber posts & trusses for simple cases. (No mathematical analysis for timber trusses).

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.
