Calculating bolt size required to prevent beam bending

  1. Apr 8, 2010 #1
    The attachment shows a side section of a water tank.(lined with Marine Ply)

    The section will be bolted to a fixed bottom section with 4 bolts.

    I'm trying to determine the size and strength of bolts required to do this.

    My attempt at starting this problem is shown in the attachment.

    Ive calculated the the hydrostatic force on the section.
    The pressure on the section varies with depth from 9810pa to 0pa at the top.

    Is this a varying uniform load beam problem?
    Or is it a point load problem acting at the centroid of the triangle (2/3rds of the way down)

    Am I wrong here?

    Also where do I go from here to calculate the minimum strength of each of the four bolts to prevent the section from bending?

    I don't follow what you are asking.

    What about the corner forces with the other two sides?
