Prerequisite
Structural Analysis-I & II, Concrete technology, Design of Reinforced concrete structure
Rationale
For improving the behavior and strength of concrete structure under various service conditions, prestressing is one of the most effective methods. It is widely used in long span building structures and bridges. Bridge is an important infrastructure facility required to construct for passage over railways, road ways etc. Hence this subject is designed to combine both things, which are most relevant to the field of Civil Engineering. The subject focused on various aspects related to design of prestressed concrete slab & girders and design of the simple girder type bridges. This course would add the knowledge of designing long span structures using prestressing.
Course Outcome
After learning the course the students should be able to:
1. apply concepts & methods for pre stressing systems for different materials.
2. compute stresses in beams due to transverse loads & prestressing.
3. determine the losses in beams due to prestress, short and long term deflection, flexural and shear strength of beam.
4. design the pre-tensioned and post-tensioned concrete beams & slab, anchorage zones.
5. know various specifications of IRC for planning, analysis & design of bridges.
6. analyse and design of simply supported RC slab & girder type superstructure as per IRC specifications,
7. analyse and design substructure, foundation and adjoining elements.

Active Learning
Preparation of power-point slides: which include videos, animations, pictures, graphics for better understanding theory and practical work. The faculty will allocate chapters/ parts of chapters to groups of students so that the entire syllabus can be covered. The power-point slides should be put up on the web-site of the College/ Institute, along with the names of the students of the group, the name of the faculty, Department and College on the first slide. The best three works should submit to GTU
