Steel Moment Frame

Professional Moment Frames in the GTA

Konstruction Group fabricates and installs steel moment frames for multiplex and commercial construction throughout Toronto and the GTA. Moment frames are essential in most multiplex projects - they resist lateral forces through rigid beam-to-column connections, enabling open floor plans without diagonal bracing. We handle the complete process: in-house detailing, CWB-certified fabrication, and professional on-site installation. Because moment frames are integral to our multiplex framing work, coordination with insulation and drywall is seamless.

What is a Moment Frame?

A moment frame is a structural system where beams and columns are connected with rigid joints that resist rotational forces. Unlike pinned connections that allow rotation, moment connections transfer bending moments between members, providing stability against lateral loads. This allows buildings to resist wind and seismic forces without the diagonal bracing that would obstruct open spaces.

Moment Frame Services

• Moment Frame Design Coordination – Working with structural engineers to develop practical moment connection solutions
• Custom Fabrication – Steel moment frames fabricated to engineering specifications with proper weld details
• Beam-to-Column Connections – Rigid welded and bolted moment connections per approved connection designs
• Field Installation – Professional erection and connection of moment frame components on site
• Seismic Moment Frames – Special moment frames designed for seismic resistance where required
• Inspection Coordination – Third-party weld inspection and documentation as required by specification

Types of Moment Connections

• Welded Flange Connections – Beam flanges welded directly to column flanges - common for full moment transfer
• Bolted End Plate Connections – End plates welded to beams and bolted to columns - allows field adjustment
• Extended End Plate – End plate extends beyond beam depth for increased moment capacity
• Reduced Beam Section (RBS) – Dog-bone cuts in beam flanges to control plastic hinge location in seismic applications

Moment Frames in Multiplex Construction

Moment frames are standard in most multiplex projects we build - duplexes, triplexes, and fourplexes throughout Toronto. These multi-unit buildings need lateral resistance for wind loads, and moment frames provide this without diagonal bracing that would interrupt floor plans. Because we handle the steel moment frames along with framing and soundproofing, the entire structural system coordinates seamlessly. Our crews install the moment frames and frame around them as one integrated operation.

Applications

Beyond multiplexes, moment frames are ideal for commercial buildings, retail spaces, and custom homes requiring open floor plans or large unobstructed spaces. Any building where diagonal bracing would obstruct openings or circulation benefits from moment frame design. Moment frames provide flexibility for future layout changes and tenant improvements.
