| چکیده | ||
| In contemporary steel frame construction, semi-rigid joints are increasingly recognized for their ability to balance internal forces and limit stress concentrations. Most existing studies primarily focus on joints at beam–column intersections, while practical construction often introduces additional joints at mid-span when members are segmented and assembled on site. This research applies a finite element approach with geometric nonlinearity (P–Δ effect) to examine how the location of semi-rigid joints affects the static stability of planar steel frames. Both conventional end-joint configurations and alternative mid-span layouts are analyzed. The model, verified against benchmark results, is then used to explore variations in buckling load, deformation patterns, and moment distribution. The findings show that relocating joints to mid-span can enhance the critical load capacity by more than 230% in certain cases, emphasizing the structural significance of connection positioning. Based on these insights, practical recommendations are proposed for prefabricated steel structures with non-traditional connection arrangements. | ||
