Parametric Structural Steel Knife Connection

This parametric structural steel knife connection for Revit facilitates precise beam-to-column joint detailing in BIM projects. The assembly features a central steel knife plate integrated with a bolted angle configuration, designed for connecting structural members to columns. The geometry includes a vertical plate slotted into the beam web, secured with high-strength bolts visible in both the 3D perspective and orthographic views. The component is engineered to handle standard structural steel profiles, providing a clean, technical interface for primary frame connections. Its proportions are consistent with industry-standard steel fabrication, ensuring that the connection appears realistic in both coarse and fine detail levels within a project environment.

The download is a 932 KB file containing a Revit family (.rfa). Load it into a project from the Insert tab with Load Family, then place it like any other component of its category; it schedules and tags with the rest of your model.

Engineers can load this family into a project and host it directly to structural framing elements. By adjusting the built-in parameters, the connection dimensions can be modified to suit specific beam depths and column sizes. It is best practice to utilize the family in conjunction with standard steel sections, ensuring that bolt patterns are checked against structural calculations. The component supports standard Revit tagging and scheduling, making it efficient for generating detailed steel assembly documentation and bills of materials.
