“…The proposed connection exhibited stable hysteresis cycles without degradation up to a story drift of at least 6% and satisfied the AISC341‐16 seismic provisions as a special moment connection . The proposed connection uses the idea of omitting horizontal diaphragm and replacing it with a vertical through plate, thereby creating new paths for load transfer in the panel zone . In through plate connections, all capacity demands of the beam are primarily transferred to the through plate via in‐plane action and then to the column.…”

Summary The through plate connection has a practical reliable configuration for fully restrained connections for a steel I‐beam to hollow or concrete‐filled tubular columns in seismic areas. Based on experimental programs of authors on interior planar moment connections via through plate technique, this paper presents the outcome of the studies focusing on the joint behavior and the shear transfer in the panel zone of through plate connection. Based on the conducted approved three full‐scale tests, the behavior of connection components and panel zone shear force were investigated accurately in order to provide useful information and key parameters to facilitate design calculations and proportioning the connection. The contribution of each component in the total shear capacity of the panel zone region was determined. Load transfer mechanisms were explained and by quantifying the portion of load transfer paths, the calculation approach was described for design purpose. The proposed design procedure was validated for a wide range of beam to column connections using finite element models. Verified numerical models were used to conduct parametric studies. The numerical results revealed that the proposed analysis method can predict well the induced demand in the connection components and also the design procedure is suitable and secure for all cases.
