“…The cyclic response of non-ductile reinforced concrete frame was studied by Oinman et al (2014). They showed that the addition of steel fibers in the critical location of beam-column joints enhanced the lateral load resistance capacity and corresponding lateral drift.…”

An experimental study has been conducted to study the cyclic behavior of reinforced concrete beams in which steel fibers were added to the concrete mix. Seven similar geometrically specimens in full scale were studied under four-point bending test in the form of slow cyclic loading. One sample as a control specimen was made without steel fibers or 0% volume fraction (vf) and six other samples with 1, 2 and 4% vf of steel fibers in twin models. The maximum and ultimate resistance, ductility, degradation of loading and unloading stiffness, absorption and dissipation of energy and equivalent viscous damping were studied in this investigation and the effect of steel fibers on the cyclic behavior was compared with each other. Generally, the addition of steel fibers up to a certain limit value (vf = 2%) improves the cyclic behavior of reinforced concrete beams and results in the increase of maximum strength and ultimate displacement.

“…The study on thirty-two simply supported reinforced concrete (RC) beams with high-strength stirrups presented the effects of the yield strength of shear reinforcement and the compressive strength of concrete on the shear behavior of RC beams (Jung-Yoon, Im-Jun, & Sang-Woo, 2011). The addition of steel fiber-reinforced concrete at the critical regions can enhance the seismic performance of reduced-scale gravity-load designed test frames (Oinam, Sahoo, & Sindhu, 2014). The experiment results showed that the addition of steel fibers improved the damage tolerance, lateral load resisting capacity, lateral stiffness, ductility and energy dissipation of the frame.…”

In this paper, four concrete frame joints with high-strength stirrups and one with normal-strength stirrups were tested to investigate the mechanical properties of concrete beam-column joints with high-strength stirrups under low cyclic reversed loading. The influences of yield strength, volumetric ratio and section type of stirrups on bearing capacity, ductility, energy dissipation and shear deformation of concrete joints were analyzed, and the results indicate that increasing the yield strength of stirrups has limited effect on enhancing the bearing capacity of concrete joints, but can effectively improve the ductility, energy dissipation and restriction on shear deformation of concrete joints.

Past earthquakes have brought attention to the poor performance of precast reinforced concrete structures, especially relating to beam-to-column connections. The evaluation of different methodologies for the analysis of beam-to-column connections in industrial buildings is important. In the present work numerical analyses developed allowed the study of the effect that different story heights and connection properties have on frequencies, drifts, seismic coefficients and connection sliding. The results showed that the friction between concrete elements and the consideration of neoprene have a small impact on the drift demands in the columns and the seismic coefficients of the structures analyzed; on the other hand, the effect of steel dowel on the drift demands and seismic coefficients is significant. The comparison of models with different properties and connections allowed a better understanding of the parameters that affect the seismic behavior of precast reinforced concrete buildings the most and provide indications for building more accurate and efficient numerical models.
