Design Model of Joints for RCS Frames

Seismic behavior of steel beam and reinforced concrete column connections

“…It is also noted that the post-peak deterioration of specimen ICLPS is less than that of other specimens due to the different loading protocol. Table 3 also summarizes the analytical shear strength in the panel zone, based on the research of Kanno and Deierlein [11], Para-Montesinos and Wight [7], and AIJ [13]. It was found that Kanno and Deierlein's suggestions tend to be conservative for the design of connections, when compared with the test results.…”

“…2 and 3, all specimens have the same dimensions, with the steel beam H 596 × 199 × 10 × 15 in size and 65 × 65 cm columns reinforced with 12 #11 longitudinal bars, representing beam-column connections of the first floor of the in-plane frame. According to the research of Kanno and Deierlein [11], the panel zone of beam-through-type connections can be divided into two elements: inner and outer elements. Failure modes in the inner element can be panel shear yielding or bearing failure of the column concrete, while failure modes in the outer element may be bond failure of the longitudinal reinforcement or panel shear yielding.…”

Panel shear strength of steel coupling beam–wall connections in a hybrid wall system

“…The lowest ratio was 0.92, obtained for specimen 1 by Montesinos et al [16]. The highest ratio was 1.54, obtained for Kanno's specimen OJS2-0 [15]. For specimen OJS2-0, no shear keys were used to transfer shear forces to the outer connection regions.…”

“…The joint details included face bearing plates, steel columns embedded in the RC column, dowel bars, and shear studs attached to the beam flange. Kanno and Deierlein [15] reported the testing of 19 interior RCS composite joints, subjected to cyclic loading, at Cornell University. This research investigated different joints and has extended the joint behaviour models to account for different joint details and different stiffeners and shear stud arrangements, as well as for the presence of transverse floor beams.…”

Cyclic Testing of a Composite Joint between a Reinforced Concrete Column and a Steel Beam

“…To effectively apply RCS frames in a real structure, it is necessary to study the composite connection between steel beams and reinforced concrete columns. Extensive studies have been conducted to study the basic force transfer mechanisms in connection regions and the performance of various joint configurations that enhance the connection performance under seismic excitations [1][2][3][4][5]. The American Society of Civil Engineers [6] published design guidelines for composite RCS joints in low to moderate seismic regions.…”
