ST4071 Advanced Prestressed Concrete Syllabus – Anna University PG Syllabus Regulation 2021
OBJECTIVE:
To develop an understanding of the philosophy of design of prestressed concrete
To be able to design indeterminate prestressed concrete structure
To design the prestressed concrete bridge and composite sections.
UNIT I INTRODUCTION
Concepts of Prestressing – Materials and methods of prestressing – Design philosophy- Analysis methods, Time-dependent deformation of concrete and losses of prestress.
UNIT II DESIGN FOR FLEXURE, SHEAR AND TORSION
Behaviour of flexural members, determination of ultimate flexural strength using various Codal provisions – Design for Flexure, Shear, torsion and bond of pre-stressed concrete elements – Transfer of prestress – Box girders – Camber, deflection and crack control.
UNIT III DESIGN OF CONTINUOUS AND COMPOSITE BEAMS
Statically indeterminate structures – Analysis and design of continuous beams and frames– Choice of cable profile – Methods of achieving continuity – concept of linear transformations, concordant cable profile and gap cables – Composite sections of prestressed concrete beam and cast in situ RC slab – Design of composite sections – Partial prestressing – Limit State design of partially prestressed concrete beams
UNIT IV DESIGN OF TENSION AND COMPRESSION MEMBERS
Pre-stressed concrete compression and tension members – application in the design of prestressed pipes and prestressed concrete cylindrical water tanks – Design of compression members with and without flexure – its application in the design of piles, flag masts and similar structures – Two way pre-stressed concrete floor systems – Connections for pre-stressed concrete elements
UNIT V DESIGN OF PRESTRESSED CONCRETE BRIDGES
Review of IRC and IRS loadings. Effect of concentrated loads on deck slabs, load distribution methods for concrete bridges. Analysis and Design of superstructures – Design of pre-stressed concrete bridges incorporating long-term effects like creep, shrinkage, relaxation, and temperature effects, Dynamic response of bridge decks.
OUTCOMES:
On completion of the course, the student is expected to be able to
CO1 Identify the various methods of prestressing and estimate the loss
CO2 Design the beams for flexure, shear, bond and torsion
CO3 Design the continuous beams and composite beams
CO4 Design the water tank, piles and masts
CO5 Analyze and design the prestressed concrete bridge
