 to this class of dynamics of a structure. In this class, we would be learning how to analyze structures and systems subject to dynamic loads. So, we will start the course by simplifying systems to a single degree of representation or a multi-degree of freedom representation. And for both type of representation, we will see how to analyze those systems subject to different type of loadings which we might encounter in real life. And some of those loadings could be initial condition or it could be harmonic or periodic motion or it can also include the arbitrary pulse type motions or triangular loading and those are simply representation of different type of loads that they are subjected to. And then we will also look at that how to analyze single and multi-degree of freedom system subject to non-uniform or non-purity loading which could include earthquake or seismic loading or wind type loading. And we will learn about numerical methods that can be employed to find out solutions or the response of system subject to dynamic loads in cases where the analytical solutions might not be available. Then we will look it into the simplifying continuous structural members so that they can be analyzed a single degree of freedom system and we will see the concept of shape function and shape vector. Then we will get into multi-degree of freedom system and learn about what do we mean by mode shapes and modal frequencies. And then we will see how to analyze multi-degree of freedom system subject to different type of loadings using modal superposition methods and how to extend that through different analysis methods as well. And towards the end of this course we are going to look at some real life examples of dynamics of structures which are utilized to analyze or design specific type of seismic protective systems. So, by end of this course you would have adequate knowledge to interpret the behavior of structure subject to dynamic loads as well as you will possess the required skills to find out the response of the structures subject to dynamic loads. All right, thank you.
