edge distance ties too tight
edge distance ties too tight
(OP)
i have a small concrete block on top of a steel beam. there's an equipment saddle with bolts on top of the concrete. the bolts will be connected to the steel beam as shown in pic.
my main concern is the concrete - 700mmx200mm. i want to put ties around the bolts but it seems too tight.
what is the minimum rebar you will put in this concrete to prevent cracking? say forces are negligible

As for the concrete block; you mention that this is an equipment saddle. What loads does it have? Gravity I assume but will the equipment try to move the beam/concrete laterally? If the loads are small (and you fix the bolt issue) I imagine that this may work. I don't think you would need ties either way but that depends entirely on the code you have to follow and the loads applied. I saw you put in a stiffener, was this due to web crippling calculations or just from engineering judgement?
