摘要

Beam-column joints of reinforced concrete building frames play an important role under seismic excitations.These are one of the most congested areas in reinforced concrete framed structures; placement of concrete andproper compaction in such areas are hence substantially challenging. This offers a unique area of application forself-compacting concrete which can flow through every corner of extensively reinforced area without anyvibration. Therefore if implementing self-compacting concrete in beam-column joints does not compromiseseismic performance of the frame, it can be used instead of conventional concrete.This paper focuses on implementation of high-strength self-compacting concrete in beam-column joints andassessment of its seismic behaviour under reversed cyclic loading. Three interior beam-column subassemblieschosen to vary in concrete type and compressive strength are designed as per the New Zealand StandardNZ3101:2006. The specimens are instrumented to measure the load, displacement/drift, ductility, joint sheardeformations, and elongation of the plastic hinge zone. The cracking pattern at different load levels and the modeof failure are also recorded and compared among different specimens.
