Rebound Theory – Characteristic of earthquake – Estimation of earthquake parameters - Magnitude and intensity of earthquakes – Spectral Acceleration. Two degree of freedom system – modes of vibrations – formulation of equations of motion of multiĭegree of freedom (MDOF) system - Eigen values and Eigen vectors – Response to free andįorced vibrations - damped and undamped MDOF system – Modal superposition methods.Įlements of Engineering Seismology - Causes of Earthquake – Plate Tectonic theory – Elastic UNIT II MULTIPLE DEGREE OF FREEDOM SYSTEM Undamped structures – Response to harmonic and periodic forces. System - D’Alemberts principles – effect of damping – free and forced vibration of damped and Structure as single degree of freedom system – Formulation of Equations of motion of SDOF Loading is also one of the focus of the course.ĭifference between static loading and dynamic loading – Degree of freedom – idealisation of The detailed study on the performance of structures under earthquake Different types of dynamic loading also toīe discussed. Performance of the structures to the students. The main objective of the course is to introduce dynamic loading and the dynamic
