Abstract
An apparatus for visually or audibly displaying swinging reducing effect in a structure with a damper or a base isolator, which reduces swinging of building structure during earthquake and increases performance characteristics and structural safety of the structure. The apparatus comprises an earthquake observation device, a computer, a display unit and a communication system for connecting the earthquake observation device, the computer and the display unit. The earthquake observation device records input seismic wave to the structure and response wave of the structure at each given time, and the computer calculates response in case the structure is not provided with damper or base isolator, using dynamic characteristics of the structure and input seismic wave in observation records. Thus, the input seismic wave, observed response wave with damper and base isolator, calculated response wave without damper or base isolator, as well as damping effect and base isolation effect are given on the display unit.
