Tartalmi leírás:
Buckling Restrained Braces (BRB) are innovative displacement dependent devices having balanced hysteresis behaviour. Frames equipped with such devices are known as Buckling Restrained Braced Frames (BRBF). The fact that there is no European standardized design procedure available for the BRBF system, seriously limits the application of BRB elements in Europe.
The paper proposes a Eurocode conforming design procedure for BRBF, providing the seismic design parameters and capacity design rules, by updating the specifications of Eurocode 8 on steel Concentrically Braced Frames. The suggested modifications are explained and illustrated via brief examples. The design method is illustratively introduced by numerical example of BRBF system, highlighting the special aspects of the design process. The design method is justified by the help of the FEMA P695 methodology. The methodology has been implemented in a software environment that is capable of automatic evaluation of the performance of structural archetypes with the help of the OpenSees finite element code. The seismic performance assessment required extensive experimental studies on BRB behaviour and development of novel material model capable of complex nonlinear hardening behaviour under irregular cyclic loading. Applicability of the developed design procedure was confirmed through the design and collapse probability evaluation of 24 BRBF archetypes.
