Finite element simulation of the device CAR1 on braced frames

Résumé

The developed device, has the codename CAR1, belongs to the passive energy dissipation systems, as it doesn't require external power to generate system control forces. It can be used on new or existing structures and can be easily adapted to the particular demands of structures. It can be installed in a variety of ways such as in single or X diagonal bracing in building frames. Moreover the use of this device may result in improving (i) the increase of stiffness (ii) the absorption of seismic energy, (iii) as well as control of the axial forces that are developed at the diagonal steel braces. The main part of CAR1 device is the groups of superimposed blades, which absorb seismic energy through simultaneous friction and yield. Firstly this paper discusses the experimental and numerical evaluation of the effectiveness of this steel device. Full scale CAR1 device was experimentally investigated under cyclic loading in Laboratory for Strength of Materials and Structures of Aristotle University of Thessaloniki. Finite Element Models of CAR1 device were developed and analyzed using the software ABAQUS, checking the credible documentation of the device. In addition, a numerically robust finite element model of a whole one storey structure is described, for highfidelity simulations of inelastic responses of device CAR1 on braced frame. Aim of this study is to compare the response of one storey structure with and without the existence of device CAR1 on diagonal braces.
