Plastic Hinge Relocation of Interior Beam-column Concrete Frames using Longitudinal Intermediate Bars
Keywords:
Interior sub assemblage frame, Plastic hinge, Intermediate bar, Cyclic loadAbstract
This paper presents experimental results aimed at studying the behavior of two interior monolithic concrete beamcolumn sub assemblage frames having different reinforcement details under cyclic loading. The first specimen M1,the joint was seismically detailed according to ACI352R-02 and used as a reference. The M2 specimen was identical to the specimen M1 with additional longitudinal intermediate bars embedded in joint area and two beam edges. From the test results, the longitudinal intermediate bars significantly improved the cyclic behaviors i.e. higher capacity, ductile failure mode, more energy dissipation and decrease of stiffness degradation.
