Multi bolt patterns on thin uniform brackets ( h ttp://oducts/mot orsandwhee ls/easy-ro ller/brack et-750.jpg) rarely distribute loads in a simple geometrical way. The thickness and other geometry of the bracket can change the bolt loading significantly, and in ways that basic static analyses miss completely, and are not always 'intuitive.' For instance, if a gusset or rib is involved, bolts further than a few diameters from the rib rely on the basic brackets thickness, and may be subjected to very little of the axial load.

Now greg'll post that you can't solve the problem 'cause it's redundant (sorry mate, needless dig !!. RF = reserve factor = 1 + Margin of Safety Now you have to combine these loads together. these bolts are also supporting the weight in shear, W/4. this is a simplification, you could say that the angle is 'heeling' at it's bottom edge (this'll give you a wider moment base, and slightly smaller loads). the bolts react this moment as a couple, if the bolts a pitched p (' of mm) apart and if there are 4 bolts (2 pairs) then the tension load on the bolt is (W*d)/(p*2). weight = W (lbs or N), distance d (' or mm). Your post could have meant you were mounting a picture (to continue the wall reference), pretty much in the plane of the wall, so the bolts would only be loaded in shear (by the weight).Д«ut your supporting something away from the plane of the wall. Yeah, i think that's pretty much what we had in mind. RE: Bolt Calculation VDI 2230 dimjim (Mechanical) 15 Feb 08 09:05

I recommend purchasing the standard and one of the available commercial software packages.

Then, calculate stresses, surface pressure, fatigue, thread engagement, etc. Then, you determine the minimum required preload: friction grip to resist transverse forces, or sealing against a medium, or to prevent opening along the joint interface(s). This is done with simple statics, finite-element calculations, etc.ДЄfter you have local conditions, then you input your joint geometry and materials. So, first you need to transform your global forces (applied forces, reactions, etc.) into a local condition at the fastener. VDI 2230 is used to analyze the situation at the actual fastener location. Perhaps you meant axial, in contrast to transverse. Your force is not concentric, it is eccentric.
