  • Multi Span Steel Portal Frame

Multi Span Steel Portal Frame
A multi-span portal frame is an extended version of the single-span design, commonly used for large industrial facilities, warehouses, and commercial buildings. It consists of multiple interconnected portal frames, typically with intermediate columns supporting a series of roof beams. This configuration allows for wider building widths while maintaining structural stability. The rigid connections between columns and beams provide excellent resistance to vertical and lateral loads, including wind and seismic forces. Steel is the preferred material due to its strength and ease of prefabrication. The design offers cost efficiency, fast construction, and flexible interior layouts without obstructive columns. Bracing systems ensure overall stability, making it ideal for long-span, low-rise structures requiring open floor space.
