Course description and aims
As a basic mathematics, Fourier transform and the concept of frequency domain are introduced. Formulation and solutions are discussed for one degree-of-freedom (1DOF) system with and without damping. The frequency response functions are also discussed for 1DOF system. Basics of multi DOF system are introduced and theoretical background are shown for damping and isolated systems for structures on the basis of the multi DOF system. Finally, formulation and solutions are discussed for free oscillation of simple beams.
To use the resulted equations is important. However, it is much more to understand how and why we reach the results. Thus, this course devote time to discuss the procedure of analysis and theoretical background.
Student learning outcomes
Objective is to understand the basics of structural response during earthquake ground motion. (1) Understanding 1DOF system, (2) understanding multi DOF system, (3) understanding basic concept of damping and isolated system for structures, (4) understanding dynamic response of beams, (5) understanding basics of earthquake-resistant design for structures.
