Seismic performance of reinforced concrete interior beam-column joints with novel reinforcement detail

The Behavior of Interior Beam-Column Joint Models Using Self-Compacting Concrete with Variations of Shear Reinforcement Subjected to Cyclic Lateral Loads

“…This study requires data on the dimension and reinforcement detail of IBC joints, steel bar, Normal Concrete (NC) material properties, and applied axial and lateral cyclic loads. The secondary data used for NC was obtained from the previous research [11]. The concrete compressive strength and modulus of elasticity were 46.5 MPa and 32049 MPa, respectively.…”

“…The SCC material properties were obtained from previous studies [17] with a compressive strength of 41.813 MPa and elastic modulus of 30391 MPa. The steel bar properties used for modeling were referred to the previous research [11] in Table 1 where 𝑓 𝑦 and 𝑓 𝑢 are yield and ultimate strengths, respectively.…”

“…The IBC joint model's detailed dimension was referred to in the previous study [11] and based on a code [18] in Figure 1. The column had a cross-sectional dimension of 300mm×300mm with 8 D16 longitudinal reinforcement and D10-100 stirrup reinforcement.…”

“…The experimental works of IBC joint specimens [11] were modeled and analyzed based on the Finite Element Method (FEM) using ANSYS software. For modeling verification, the hysteresis curves of the experiment results of the NC-S3 specimen had been compared with the NC-S3 model.…”

“…The reaction of the structure specimen resulted in hysteretic curves as a correlation of load and displacement. The nature of dynamic loading is loading and unloading [11]. As the horizontal displacement increases, more cracks are formed along with the structural elements, depending on the direction of loading [9].…”
