Abstract
According to the present invention, an analysis system constructed as a rheology model of a foundation-ground system that is capable of expressing a frequency dependent dynamic spring by using elements with non-frequency-dependent coefficients may be provided. The analysis system according to the present invention is a model for reproducing dynamical characteristics of a system including the foundation and the ground. The analysis system includes an elastic element, a damper element for damping vibration, and a reaction force generation element that generates reaction force proportional to relative acceleration of both ends thereof. The analysis system is constructed as a base system in which the elastic element, the damper element and the reaction force generation element are connected in parallel. Also, the analysis system may include at least one core system provided with any of two elements among the elastic element, the damper element and the reaction force generation element connected in parallel, and a remaining element connected serially thereto. And the base system and at least one core system may be connected in parallel to construct the analysis system.
