How to calculate permanent load?

  1. Jun 21, 2013 #1
    Hello, I am trying to calculate the permanent load on a slab of 1.6m x 1.4m x 0.05m stainless steel that is part of a structure of 8 plates.
    The structure is a rolling bridge, link below


    I'm trying to calculate, Load per square meter structural and non-structural,Maximum stress for permanent loads,Analysis of traffic load.

    Anyone can help me with the formulas that i have to use for this as I don't know which to use? Thank you very much in advance

    The structural load is just the weight of the bridge "smeared" over the area, often with some factor to account for it weighing more (or less) than you think. What do you mean by non-structural? People walking on it or decorative panels. Permanent loads typically means just the structures weight with all of its "accessories". The max stress from permanent loads is most likely going to occur when the bridge is "Rolling up".
