Hello!
When designing beams, deflection calculation is mandatory?
When designing beams, deflection calculation is mandatory?
Getting figures for both bending stiffness and shear stiffness for scaffold beams is pretty much impossible and assessing the effect of wear and tolerances on connections is difficult. Working out how to add in the stiffening effect of any scaffold above or below the beam is as complicated an art as I could think of in design.
If you think that you are doing an accurate calculation for deflection you are probably deluding yourself but I wait to hear what everyone thinks is reasonable.
I know that some manufacturers have tried to provide standard solutions for some fairly well defined load cases but don't think that the people who drafted the Eurocode were ever involved in day to day design with the pressures of deadlines and economics bearing down on them and what is written therein is not practicable.
