Uni and bi-directional quasi static tests on alternative hybrid precast beam column joint subassemblies

摘要

Recent developments on high performance seismic resisting precastconcrete frame systems, based on the use of unbonded post-tensioned tendons with selfcentringcapabilities in combination with additional sources of energy dissipation, areherein presented. Alternative arrangements for jointed ductile connections toaccommodate different structural or architectural needs have been implemented andvalidated through quasi-static cyclic tests on a series of 2/3 scaled beam-columnsubassemblies under uni- or bi-directional loading regime. The satisfactory resultsconfirmed the unique flexibility and potentiality of the proposed solutions for thedevelopment of the next generation of seismic resisting buildings.
