No we have not. I don't believe we have any of the broken springs either. I have only worked here for 3 weeks and this isn't my project, its just I have a better grasp on metal working than the girl who's project it is. We had a spring from a different supplier that we did not have any...
I wound up finding a diagram for this alloy after posting, but I appreciate your reply. It is a coil spring on one of those animal shaped rockers at the park. We've been having the spring fail, the casting that holds down the spring fail, and also the bolts shearing off. From my digging it...
We have a coil spring made of 5160H alloy steel. In our shop we powder coat the spring, which it is held at 400*F for roughly 25 minutes. We have been experiencing some spring breakage and one thought was we used to paint the spring and bake it at 400*F for 5 minutes. There were some other...
Don't worry, I've calculated the factored load for soil pressure including the dead load of a full ammonia tank and also snow load. The slab doesn't see any vehicular or foot traffic so no live load. Have all the calc's done now, just have to make them pretty with some fancy diagrams and write...
Density X Volume=Weight Weight/Area=Soil Bearing Pressure And the soil bearing pressure is used as the basis for all the other calculations for strength. Bear with me, never EVER designed or have any experience with reinforced concrete...so I'm learning as I go... I'll work on a sketch and...
Thanks guys, I'll just stick with 145 to split the difference, I was only 7 days old when the pad was designed (3/7/85) so I don't have a lot of info to go off of as far as aggregate type. The reason for calculating is our ammonia tank skid has a small tweak in it, which makes it not contact...
As the title says, I'm trying to calculate the weight of the slab. I've found a standard 145lb/cf number, but I'm looking to be more specific as to the exact concrete that was used. Trying to verify proper design/construction of a 50'x10'x8" pad. Thanks! Christian
Thank you, at least I have a direction to head! Is there anywhere you know of that has this sort of info? #3 is easy as there is no anchoring hardware. #2 is easy enough if there is somewhere that lists the soil pressures/max loads. #1 I would need to find equations for if you know of any...
Hey everyone, I'm a Mechanical Engineer and do not have experience with slabs. I've done a lot of digging around the internet and can't find anywhere that says how to calculate required slab thickness for a pad. We have an ammonia tank (77,000 lbs) mounted on an 8" thick slab. I haven't taken...
