Earthquake Engineering detail syllabus for Civil Engineering (96), M scheme is taken from TNDTE official website and presented for diploma students. The course code (31083), and for exam duration, Teaching Hr/week, Practical Hr/week, Total Marks, internal marks, theory marks, duration and credits do visit complete sem subjects post given below.
For all other civil 6th sem syllabus for diploma m scheme tndte you can visit Civil 6th Sem Syllabus for Diploma M Scheme TNDTE Subjects. For all other Elective Theory II subjects do refer to Elective Theory II. The detail syllabus for earthquake engineering is as follows.
Rationale:
Diploma holders in civil engineering have to supervise construction of various earthquake resistant buildings. Therefore, the students should have requisite knowledge regarding terminology of earthquake and the precautions to be taken while constructing earthquake resistant buildings
Objectives:
On completion of the course, the student will be able:
- To know the causes and consequences of earthquakes;
- To understand the magnitude and effects of earthquakes on structures;
- To understand the behaviour of various types of buildings during earthquakes;
- To know about the design concepts of earthquake resisting buildings;
- To know the methods of evaluation and retrofitting of damaged structures.
