I am specifically working with cases where I have multiple single anchor bolts connected to the same block of concrete. For example I might have a two meter long concrete beam and anchor bolts with a specific load every 400 mm. I would like to find out what the capacities of the anchor bolts are including the effect of the specified edge and spacing distances. In my cases the anchors are not included in one baseplate, all anchors are single anchors.
How do you recommend that I shall input the calculation data in order to have a valid design for my cases?
Thank you for your question. I can only suggest taking a conservative approach and use the half distance between anchors and using that within the software. For example if your fasteners were every 400mm c/c then model an area of 200mm either side of the fixing as edge distances and again above and below if applicable which should give you a conservative area of concrete as a guide to checking the load resistance of course, you could then also look at carrying out onsite testing for further reassurance..
