    Butler Building truss purlin

    As some of you are probably aware Butler buildings uses an unusual cold rolled section for their truss purlin top and bottom chords. Has anyone ever had to reinforce a truss purlin due to a point load located off of a panel point? What does that detail look like?

    Project in Brazil

    I am working on a retrofit project at a plant in Brazil. The existing drawings given to us appear to have Canadian steel shapes (W150x13, W200x28.8, etc.). Is this common in South America?

    I am working on a connection detail that I would like some input on. It involves new beams going over top of an existing column.

    Bridge Crane Side Thrust

    I am designing some new bridge crane runways for a client. When determining the side thrust load to the columns, is that load split between each side (50%) or applied 100% to each column. For example: Side Thrust load= 60k. Is that 30k to each side or 60k to each side.

    Column Base as Fixed or Pinned

    Let's say the bottom of your column member has a 4 bolt base plate connection to the foundation. Do you consider this as a fixed condition or a pinned condition. At what point do you consider there is some rotation at the base plate for which a moment or fixed condition would not be...

    V8 Units Display

    When drawing in "feet and inches", if I have a dimension that is an even foot (ie. 28ft.) V8 only shows it as 28'. I want it to display 28'-0". It will work if I have a dimension such as 10'-8" but not if it were 10'. I have checked that my sub units are turned on in the design file and my...
