Course Aim: To provide basic knowledge on prestressed concrete (PC) and water retaining structural design so that students will be able to design simply supported PC beams and concrete water retaining structures.

Intended Learning Outcomes:

On successful completion of the course, the students should be able to;

➢    describe the attributes of PC structures, prestressing concepts, construction methods, prestressing techniques, and applications

➢    appreciate specific design requirements and integrate structural analysis and crack controlling to design water retaining structures

➢    design prestressed concrete beams conforming to a standard code of practice.

➢    design water retaining structures conforming to a standard code of practice.

Course Content:

➢    Introduction to prestressed concrete: Historical development, basic concepts, high strength materials, pre-tensioning and post-tensioning, devices, definitions, applications, use of codes of practice

➢    Serviceability Limit State (SLS) design: Limits on stress, section design, Magnel diagram, cable profile, debonding, deflection

➢    Prestress losses: Short-term and long-term losses

➢    Ultimate Limit State (ULS) design: Flexure and shear

➢    Design of composite beams: Composite design, un-propped and propped construction

➢    Anchorage design: End block behavior, design of end block reinforcement

➢    Applications in bridges: Bridge beams, beam launching, introduction to bridge loading

➢    Introduction to water retaining structures: Structural types, joints, code of practice

➢    Concrete cracking: Types of cracks, crack formation principles, controlling of cracking, crack width calculation

➢    SLS and ULS design: Structural analysis, design for flexure, axial, shear, and combined actions

➢    Assignment 1 (individual): Design of a composite prestressed beam

➢    Assignment 2 (group): Design of a water retaining structure with computer aided structural analysis
