Live Load Span Tables
Posted on 3rd October 2020 at 20:52
Sample load span tables based on ONE particular profile to show what depth is required for one, two or three trusses assembled from a pre determined C section.
We were asked by a client to develop load span tables for their profiles to allow their client base to select an equivalent of their trusses to a Hot Rolled Beam as a replacement.
We have deliberately hidden the manufacture and their profile, but could easily offer a range of profiles and the spreadsheet would then calculate the required truss depth based on that particular profile.
It's also 'online' and embedded as an Excel spreadsheet into this web page - so we could do the same or a design tool for you!
We normally work in #Tedds by #Trimble however for this project that wasn't appropriate so we turned to our neglected friend Excel. We still tested and verified the results in Tedds with the benefit of its units and built into data lists of UB profiles and section properties, but the published tool is Excel based.
Many years ago we had a suite of tools for design of Light Gauge Steel in Excel - known as our Toolkit and this was the inspiration for our Light Gauge Steel Toolkit over in Tedds!
Before that our Steve Napper developed a 'Take Off spreadsheet during his time designing purlins at Kingspan that totted up the cost and weight of cladding rails when the user selected the product, bay length / span and number of runs. Prior to this, and partly why Steve got into Light Gauge Steel Steve worked as a Production Engineer and developed a 'Costing and Scheduling spreadsheet' for a Knowledge Transfer Partnership he was the 'Associate' on. This ten process sheet is available, as a version in MS Access database if that's still used!
