    Washer over long slot hole

    Hi everyone, I was wondering if by thickening the plate washer, I would get away from covering the total length of the long slot (3"). If not, this would mean that at a spot where my bolt is totally at one extremity of the long slot, I would need a plate washer of about 5 1/2" long! Thanks

    Capacity of support angle

    Hello everyone, Does anybody have a site where I can see an example of how to design or verify the capacity of an angle which is anchored to a concrete wall, and which support a grating floor. The angle would be 20' in length and there are no geometrical constraint on the size of the legs...

    Section Class?

    Hi everyone, Ok, this will probably sound like a dumb question, but I'm going to ask anyways: What section class (class 1, 2 or 3) would a PL10"x3/8" belong to? (10" is vertical) The reason being, I've received a design for a ships ladder with that plate as a stringer and I want to check if it...

    Using Hilt Anchor Software

    Hi everyone Why is it everytime I try the Hilti anchor software, it never works, no anchor bolts are able to withstand the loads! For example, I have to anchor a W310x31 to a concrete wall. Concrete = 35MPa first anchor is 182mm from top of wall width of concrete wall is 300mm factored Load is...

    guradrail anchoring

    Hi Everyone I have to pick a type of anchor bolt (HILTI) for a guardrail in a parking lot, and was wondering if anyone has an example of the design procedure. I went on the Hilti site and their example is not very clear on how to use their reduction factors imposed by the spacing of the anchor...

    Seated beam connection

    Hi everyone, I'm designing a seated connection for a tubular beam connecting to a tubular column. I find that the ways i've seen to establish the required bearing length (N) are a little unclear. Since N is an important property for determining the thickness of the angle which will be used as...
