An informative hand-written notes explaining the concepts of End Offsets, Panel Zone and Moment Releases in ETABS.
Prof. Pennung Warnitchai of Asian Institute of Technology (AIT), Thailand explains the phenomenon of resonance amplification of dynamic response of structures using a simplified mode (often referred to as the Boss Model). The resonance is a phenomenon resulting in large amplification of oscilations which occurs when the frequency of a periodically applied force is same as the natural frequency of the system on which it acts. When an harmonic force is applied at a resonant frequency of a system, it will oscillate at a higher amplitude than when the same force is applied at any other frequency. [...]
