ST4009 Design of Masonry Structures Syllabus:
ST4009 Design of Masonry Structures Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE:
To design, detail and retrofit a masonry structure
UNIT I INTRODUCTION
Introduction – Masonry construction – National and International perspective – Historical development, Modern masonry, Material Properties – Masonry units: clay and concrete blocks, Mortar, grout and reinforcement, Bonding patterns, Shrinkage and differential movements.
UNIT II DESIGN OF COMPRESSION MEMBER
Principles of masonry design, Masonry standards: IS 1905 and others – Masonry in Compression – Prism strength, Eccentric loading -Kern distance. Structural Wall, Columns and Plasters, Retaining Wall, Pier and Foundation – Prestressed masonry
UNIT III DESIGN OF MASONRY UNDER LATERAL LOADS
Masonry under Lateral loads – In-plane and out-of-plane loads, Ductility of Reinforced Masonry Members Analysis of perforated shear walls, Lateral force distribution -flexible and rigid diaphragms. Behaviour of Masonry – Shear and flexure – Combined bending and axial loads – Reinforced and unreinforced masonry – Infill masonry
UNIT IV EARTHQUAKE RESISTANT DESIGN OF MASONRY STRUCTURES
Structural design of Masonry – Consideration of seismic loads –concepts of confined masonry – Cyclic loading and ductility of shear walls for seismic design -Code provisions- Working and Ultimate strength design – In-plane and out-of-plane design criteria for load-bearing and infills, connecting elements and ties. Modeling Techniques, Static Push Over Analysis and use of Capacity Design Spectra – use of Software.
UNIT V RETROFITTING OF MASONRY
Seismic evaluation and Retrofit of Masonry – In-situ and non-destructive tests for masonry – properties – Repair and strengthening of techniques.
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Explain the properties of a masonry unit and the various components
CO2 Design a masonry structure for compression
CO3 Design a masonry structure for lateral loads
CO4 Design an earthquake-resistant masonry wall
CO5 Suggest retrofitting techniques for existing masonry walls
