Design Input cum Review Record

Department: Civil Engineering For the Academic Year: 2015-2016

Semester: M.Tech Subject and subject code: Dynamics and Earthquake Engg Lab. - MSEL 27

Course Objectives:

1. Enable the students to learn the phenomenon of vibration of structures under base motions, occurrence of resonances in multi degree- of-freedom (dof) systems, normal modes and their visualization, and the nature of the frequency response functions in mdof systems.

2. To give factual knowledge to appreciate how horizontal base motion can induce torsional responses in frame

structures. The importance of angle of incidence of base motions in computing structural responses. 3. The student here would learn about the concept of displacement transmissibility and conditions under which, an

isolation device would be effective.4. To provide knowledge on structural systems subjected to dynamic loads, areas of vibrations applied to structural

systems.
