“…The experimental part of this study provided a basis for the analytical investigation. The sub‐assemblages of the experiments were full‐scale specimens extracted from an interior joint of SMRF, and they replicated the seismic behavior of rigid connections (Hosseini Hashemi and Ahmady Jazany , ). The connection detailing and welding were designed according to AWS () and AISC ().…”

“…Figure shows these connections types and their detailing for unequal beam depth. The reference test specimens of study by Hosseini Hashemi and Ahmady Jazany (, ) consisted of two categories. In the first category, which is shown in Figure (a)–(c), the flange plate connection was used for all test specimens.…”

“…The shallow beam bottom flange and the haunch flange are directly connected to the column flange by a CJP groove weld, and because of the direct connection between the shallow beam bottom flange and the column flange by means of a CJP groove weld, a middle continuity plate was used. The summary of test specimens and specifications are presented in Table (Hosseini Hashemi and Ahmady Jazany ). In the following section, the summary of the experimental results is described, and the cyclic behavioral differences of the test specimens will be discussed.…”

“…unequal beam depth. Hosseini Hashemi and Ahmady Jazany (, ) experimentally and analytically studied the effect of connection detailing arrangements for the case of unequal beam depths; they showed that some specific connection detailing arrangements can provide acceptable performance based on AISC () and prevent dominant rupture mode. Furthermore, they proposed a special detailing for the inclined continuity plate for the case of unequal beam depths (Ahmady Jazany and Hosseini Hashemi ).…”

SUMMARYThis study considers the effect of detailing of an interior beam to column connection with unequal beam depths on seismic performance of special moment-resisting frame (SMRF), which has not explicitly been taken into account, despite its possible occurrence in engineering practice, by the current codes and provisions. Studied detailing consists of a continuity plate arrangement, cover plate, flange plate and haunch connection system as alternatives in order to connect a shallow beam and a deep beam to column. To improve the understanding of seismic performance in SMRF connections, coordinated analytical and experimental studies have been conducted to examine the effect of different geometries and the mentioned alternatives on the seismic performance of SMRF with unequal beam depths. This work describes the analytical studies and includes a summary of the experimental results used in the development and validation of the analytical models; the experiment and analyses show that some detailing could provide ductile behavior with a total storey drift angle of 0.06 rad before experiencing 20% strength degradation while other detailing would not satisfy this criterion.
