Structure Earthquake Analysis Program using Computer-Aided IT Sensor

Abstract

The purpose of this study is to develop a complex test and analysis technique to improve the reliability of seismic performance evaluation of buildings, and to establish a seismic performance evaluation system using shear damper as an earthquake preparation technology. In this study, validated examples of viscoelasticity provided by OpenSees were selected for verification of hybrid experimental results data and compared with hybrid experimental techniques. By applying the analysis program and the developed Labplugin, the hybrid experimental system built through the connection between the equipment was verified. As a result, the behavior of the cyclic loading test showed the general behavior of the damper, but in the hybrid test, the behavior of the damper with respect to the ground acceleration and the decrease in stiffness caused by fracture were found. From the above comparison experiment, it can be seen that the hybrid technique developed in this study shows excellent seismic behavior compared to the cyclic loading experiment, dynamic experiment, and analytical technique. With the system built in this study, it is judged that it is possible to design a structure damper in the future. In addition hybrid experimental system will help to conduct more economical and reliable research on seismic control by applying partial experimental data to structures with nonlinear behavior in the future.
