Compressor skid anchor loads

Compressor skid anchor loads

Compressor skid anchor loads

(OP)
Hello. I’ve got some reactions from a compressor mounted on a skid. I’m using pretensioned anchor bolts to “pinch” the skid and take care of the unbalanced forces. One thing I was wondering though: on a day to day basis, there are some shears at the support points he modeled. (He basically modeled the skid with the anchor bolt locations as the support points.....but in actuality the skid has continuous support on a concrete pedestal.) So should I basically take on the shear on a support by support basis, or should I consider the fact that the sum of the forces under operating conditions is zero [putting aside lateral forces and unbalanced loads] and just go with “pinching” the frame for unbalanced forces only (unless the shear from the lateral forces exceeds the [overall] frictional resistance of the skid on the concrete)?

Thanks in advance for any insight.
