The steel detailing of the staircase shown involves precise modeling and coordination to ensure structural integrity and functional design. The primary steel components, highlighted in yellow, form the main support framework, including beams and channels, which distribute loads effectively. Secondary elements, such as treads, handrails, and balustrades, are detailed for safety and usability, with provisions for bolted or welded connections to ensure seamless assembly. The design must accommodate both architectural aesthetics and structural requirements, adhering to relevant standards like AISC or BS codes. The detailing process integrates 3D modeling tools, such as Tekla, to produce shop drawings, connection details, and material schedules for accurate fabrication and on-site installation.
