Prediction of low-cycle fatigue in a cantilever bending element: experimental tests and model prediction

Abstract

TADAS-devices are used in special moment resisting frames and needs certain relative displacements to start energy dissipating. The TADAS (triangular-plate added damping and stiffness) device is one of the examples of hysteretic dampers with elasto-plastic behavior. A TADAS-device is designed and tested on low-cycle fatigue. A test design from a preliminary test is proposed. The objective is to design a TADAS-device ant the testing set-up. The design is improved, taking into account the knowledge gained during the process
