Research progress on seismic performance of fabricated rebar reinforced concrete members(beam,columns and walls)
Fabricated rebars offer broad application prospects.First,the preparation processes of typical fabricated rebars in engineering and their current application in practical projects were introduced.Then,an overview of the research progress on the seismic performance of fabricated rebar reinforced concrete members(beams,columns and walls)was summarized,with a focus on the seismic performance experiments conducted by our research group in recent years on fabricated rebar reinforced concrete members(14 beams,20 columns and 6 shear walls).The study indicates that compared to tied rebar,concrete members using fabricated rebar techniques such as bent mesh,threaded hoops and spiral hoops demonstrate excellent seismic performance.Finally,the first domestic pioneering technical specification,which covers fabricated rebar reinforced concrete members(beams,columns and walls),was briefly introduced:Specification for design of fabricated-steel rein forced concrete structures(DG/TJ08-2414-2023).
