“…In this section, scale factor determination will be considered for normal steel moment frames. Considered frames in this section were similar to the study sample of Ghasemieh et al [9][10][11][12]. this samples are 7-storey and 12-storey.…”

“…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.

“…Then it will explore whether the more susceptible to local buckling high Y/T steel columns can be used in energy dissipative regions of steel structures. Ghassemieh et al [10] have recently reported the strong influence the loading protocol sequence has on quantifying the seismic capacity of structures through various evaluation indices, such as the energy dissipation, equivalent plastic strain, and deformation capacity, in accordance with design level and near collapse earthquakes. Krawinkler et al [11,12] introduced typical loading protocols for steel beam-tocolumn subassemblies that contain the design level seismic demand (symmetrical protocols) and the effect of large displacement pulses (typical one-sided protocols).…”

Load transmission from one element to another is achieved using steel connections, making them an integral part of any structural design. This article examines the differences between the American Codes (AISC) and Eurocode 3 for the design and analysis of steel connections. Moment connections' stiffness, strength, and ductility as expressed in both codes are the core focus of this research. Each tactic's advantages and disadvantages have been detailed, and the effect of seismic load on steel connection design has been investigated. The feasibility of using techniques like haunches and stiffeners to enhance connection design is also explored. The study focuses on moment connections and how they fare under different loads and conditions like stiffness, strength, and ductility. Additionally, the effect of seismic loading on the development of steel connections is analyzed. Finally, the significance of testing and documentation to guarantee the safety and dependability of steel connections has been evaluated. This research can help engineers select a suitable code and connection typology for their projects for improved performance of the overall structural behaviour.
