Earthquake force analysis method Dynamical method
In contrast with the static loading, dynamical analysis method is discussed. In this method, structure reflections at any point of time during the earthquake are determined by impressing accelerations due to ground motion (map acceleration) in structural basic level and performing related dynamical calculations. This method can be used in elastic linear or nonlinear analysis of the structures.
Dynamical analysis method has been suggested along with other methods in Japan and USA at the present time. In this method, structure dynamical behavior has been analyzed under earthquake mapping acceleration, and forces, anchors, tensions, and displacements are obtained. Dynamical analysis could be materialized in elastic and rigid domains. Some of the factors that make dynamical analysis method essential are:
