    Manager Says Keep the Restraints — I Think They’re Unnecessary. Who’s Right?

    Thanks for the diagram dold that is precisely what I’ve got.

    Completely agree on the section size as well. It can be reduced. I don’t want to give him a heart attack lol. I suppose the frustration I’m having is we have been asked for alternative solutions by the architect for a completely valid reason. I’ve provided that alternative solution through...

    Do you believe vibration would be an issue? I could ulander stand for the sake of restraint beams to be kept if vibration issues are mitigated from the get go. But not sure if a vibration would cause issue even without the restraints. I just feel it’s way overkill.

    Those restraint beams are spanning about 7.2m. They provide lateral restraints and reduce the buckling length of the column. The essentially behave as a tension and or a compressive member stopping the column from displacing laterally. So by removing the restraints the buckling length is then...

    Just to clarify the upper landing beam is spanning between two columns the photo doesn’t show the second column on the other side of the landing. So the upper beam isn’t a cantilever but rather a simply supported beam. Regarding the eccentricity I have allowed for this and applied moments to...

    Thanks for the response. So his comments back to me after I said it was a safety concern was if the students wanted to hang off the balustrade they could. A beam there isn’t going to make a difference. In regards to the actual design he said given kids running up and down the stairs how...

    I’m working on a project where the architect has asked us to revisit the column and beam arrangement supporting an internal staircase. Image 1 shows the current set-up and image 2 is what i have said we can achieve: The column is an SHS 200x200x16, total height 10.8m to roof. It supports...

    Eurocode Deflection Limits: Best Practices

    Hello everyone, I’m reviewing deflection criteria for a long-span steel beam designed to Eurocode standards, and I’m seeking some clarification. I’m currently limiting deflections as follows: Imposed load deflection: span/360 Total load deflection: span/250 My question is: For dead load...

    Sanity check on caissons for a carport

    Could you ask them for the calcs? and you could look through those yourself. Or even ask them this question, I’m sure they’ll give you a reason.

    Deflections for Composite steel frame with metal deck

    Hi All, I am Currently working on a car park with a composite steel frame with metal decking. The project has very tight headroom restrictions and therefore a tight structural zone allowance. The job is due to start on site very soon and it has just become aware that deflections & tolerances...

    Masonry Head Restraint Detail to underside of Metal Deck

    GeoregeTheCivilEngineer - Thank again! I am actually Specing an SMD Deck! I see these fixings everyday at the gym i go to which has an exposed celling with the MEP visible and have never noticed them. I'll look for a restraint tie with the combination of a wedge nut fixing thanks again!
