Level 3- Highly Addressed, Level 2-Moderately Addressed, Level 1-Low Addressed.
Method is to relate the level of PO with the number of hours devoted to the COs which address the given PO. If >40% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 3
If 25 to 40% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 2 If 5 to 25% of classroom sessions addressing a particular PO, it is considered that PO is addressed at Level 1 If < 5% of classroom sessions addressing a particular PO, it is considered that PO is considered not-addressed.

3. Visit to nearby multi-storeyed building/Apartment etc and collect the structural details.


4. Preparing a model of pre stressed concrete using locally available materials.

5. Understand the concept of formwork for different types of buildings and collect information about stripping times for forms for different conditions.

6. Visit to PSC manufacture site and prepare a report on methodology of different components.

7. Practical difference between RCC and PSC bridges and present it.

8. Use structural analysis software to analyse the various elements of structures

9. Prepare spreadsheet for design of RCC elements

10. Analyse the elements of structures using analysis software

11. Collect the information about Floating column and shear wall and present a seminar on it.

12. Collect the IS codes related to Design of RCC and PSC structures, make a report and present it

NOTE:

1. Students should select any one of the above or other topics relevant to the subject approved by the concerned faculty, individually or in a group of 3 to 5. Students should mandatorily submit a written report and make a presentation on the topic. The task should not be repeated among students. Report will be evaluated by the faculty as per rubrics. Weightage for 5 marks Internal Assessment shall be as follows: (Unsatisfactory 1, Developing 2, Satisfactory 3, Good 4, Exemplary 5) Reports should be made available along with bluebooks to IA verification officer
