Seismic performance of precast hybrid moment-resisting frame/rocking wall systems Available to Purchase

This paper discusses the applicability of precast hybrid moment-resisting frames (PHMRFs) combined with precast concrete rocking walls (PCRWs) for realising seismic resistance in buildings. The combined system was investigated through experimental and analytical studies. This system combines the advantages of the two types of structures, where PCRWs typically provide suitable lateral load resistance as well as better limitation of displacement in mid- to high-rise buildings, while PHMRFs provide a source of energy dissipation by the formation of non-linear hinges at the predetermined precast interfaces. The force–deformation responses of the system showed satisfactory ductility with stable flag-shaped hysteretic loops from low to high lateral drift levels up to 2·34%, corresponding to a ductility of 13·8. In addition, good agreement was observed between the experimental and analytical results. The results provide further evidence to support the use of the proposed system as the main lateral force resistance in buildings.
