Cumulative Seismic Damage Prediction of Damper in Elasto-Plastically Damped Buildings
Abstract eng: This paper discusses simplified theories on cumulative damage evaluation for elasto-plastic (EP) damper under earthquake ground motion. The theories are based on the seismic behavior of single-degree-of-freedom (SDOF) elasto-plastically damped structure, cumulative plastic deformation of damper can be clearly expressed as a function of natural period of structure and duration of earthquake ground motion as well as stiffness parameter and ductility demand. The relationship between cumulative plastic deformation of damper and its maximum deformation is also clarified. Accuracy of proposed evaluation method is demonstrated via numerous time history simulations by using a wide range of multiple-degrees-of-freedom (MDOF) models and earthquake ground motions.
