Improve Efficiency in Floor Truss Design
The use of floor trusses in the marketplace is generally low in comparison to other engineered products. Projects being explored under this initiative are looking for methods to enhance, if possible, the efficiencies in floor truss design making them more economical or competitive with other engineered products used in floor construction. Projects underway are in the following areas:
Top-Chord Bearing Improvements
Provide a methodology to determine, by calculation, the reaction limit for a Top-Chord Bearing MPC wood truss. The methodology will be able to be used in lieu of the currently published prescriptive maximum reaction limits and will take advantage of the effects of lumber size, lumber grade, lumber species, plate size and will not be limited to predetermined geometric configurations as is the current practice.
This methodology will be for use by truss engineers and truss software developers who desire to provide an alternate solution beyond the current ANSI/TPI 1 prescriptive tables.
What are the next steps?
Drafts of the methodology are currently being researched and developed by TPI member companies. Once drafts have been prepared there may be a need for additional review and comments from others prior to finalizing. If you are interested in being considered as a reviewer or just want to be kept informed of the progress just let us know by clicking on the button below. Once signed up and as the initiative gets underway TPI will contact you with further information on this initiative.
