How to calculate load and tributary width in your design calculations

Learn how to easily calculate a broad range of tributary and load widths you may encounter on your projects, and how to use the incredibly flexible load entry tools in ClearCalcs to ensure you get a great design quickly.

This month we kicked off ClearCalcs Learn Hour, a series of learning webinars about how you can accelerate your design calculations and analysis with ClearCalcs. Hosted by our Director of Customer Success, Connor Conzelman, and led by our resident Structural Lead for North America, Laurent Gérin, this month we spoke about load width and tributary width.

Determining the correct loading on your structure is one of the most important steps to getting an accurate and safe design, but calculating the correct tributary width and entering it into software can be a real pain. In this webinar, we covered the following points to help you get started with applying load width in your design calculations:

What is tributary width?

Applying loading via a distributed / tributary area is useful when designing floors, roofs, or other beams supporting slabs. The vertical or gravity loads are usually distributed one-way between regularly spaced joists or rafters, as depicted in the figure below.

In the webinar, we discussed common examples of tributary width in residential design, such as:

  • Skewed floor framing
  • Joists
  • Skewed Beam
  • Split Load
