Moment Resisting Short Wall

SteelSmart® System’s Moment Resisting Short Wall Design module provides the analysis and design procedure for the design of interior half walls, strip window framing, and parapet framing in residential and commercial cold formed steel framing utilizing the MidWall™ section. 

 Moment-Resisting Short Wall Screen

 MidWall is a revolutionary product intended to simplify and optimize the design and construction of members and anchorage connections. Available in widths of 2 ½”, 3 5/8” or 6” and lengths of 24” or 48”, MidWall is a one piece connection/framing unit which provides for optimization of materials and streamlined installation. 

The wall assembly consists of MidWall members spaced along the length of the wall with a top track spanning between MidWall members acting as a load distribution member capable of distributing localized loads to multiple MidWall sections.

An interior half wall is common in commercial and residential construction. In some applications the half wall is required to resist occupants from falling from an elevated surface or provide a handrail for climbing or stability assistance. The MidWall product meets the performance requirements for this application.

In strip or ribbon window framing application MidWall sections may be used at intermediate points along the length of the window to support the header and sill.

MidWall Parameters

In many framing applications a parapet may cantilever out from the roof level as opposed to bypassing the roof level.  The MidWall product is capable of satisfying the load requirements and providing an aesthetically pleasing solution for this application.
