“…To obtain a suitable time history load, providing catalog of proper accelerograms, which have all conditions of area perfectly and workable for structure and its element, is needed with respect to previous earthquakes. Ghassemieh et al [9][10][11][12][13] developed a new cyclic loading protocol for Western Asia; while presenting the loading protocol to evaluate steel moment connection, proposed a set of records for the West Asia region. Which shows the importance of selecting the set records in time history analysis.…”

Due to destructive effects of earthquake loads, acceptable assessment of these loads and create a coordinated approach adapted to each seismic zone, is important. In this study, the main purpose is preparing an appropriate list of far field accelerograms for nonlinear two-dimensional analyses. The main focus of this study is to evaluate all parameters affecting on proper accelerogram selection. By considering 2000 accelerograms and all effective parameters include distance, magnitude, frequency content, earthquake mechanism, soil and properties of earth layers, a list of 20 accelerograms were presented for nonlinear two-dimensional analyses. These proposed accelerograms represent the actual ground motion as much as possible. Also, the study of final scale factor of accelerograms for steel moment frame have been obtained with point-to-point difference in periodic intervals corresponding to each frame method.

“…The cyclic vertical load was applied by connecting the Mechanical Testing and Simulation MTS actuator (1) (A 150 ton, ±250 mm) fixed on the reaction frame with the beam end clamp (10) to make the floor (7) work together with the steel beam embedded with studs (6). The top of the column was connected with a hydraulic jack (3) and a loading bar (9) to limit lateral deformation, while an axial pressure with an axial compression ratio of 0.3 was applied. A mount of strain gauges and displacement meters (8) were arranged at the key positions of the stress and deformation to capture the specimens during the cyclic loading.…”

SummaryThis study investigates the seismic impact of concrete floors on reduced beam section beam‐to‐column joints through four quasi‐static cyclic tests. We examine mechanical properties, failure modes, and processes against specific criteria. Additionally, we analyze hysteretic response, energy dissipation, stiffness, capacity, and stress–strain mechanisms. Moreover, the ABAQUS platform was used to reproduce the specimen nonlinear finite element model to compare and analyze the test results. The results showed that the specimens exhibit excellent energy dissipation capacity and ductility (with a coefficient of 5.00); the column‐bar connection characteristics affect the maximum capacity and plastic hinge behavior in the reduced beam area. The reduced section of beam's upper flange could not improve the overall seismic performance of the joint. The observed failure sequence is as follows: concrete floor cracking, beam flange yielding, reinforcement fracture, lower flange yielding in the reduced beam area, and overall joint failure. This sequence confirms that the joint fulfills the design criteria of a “strong column‐weak beam” by achieving the target of plastic hinge outward movement.
