RE: Punching shear check

Hello guys:

Remember you have to provide at least d/2 clearance off the column so it can check shear.  If you fail to provide this off the face of the column you will get a n/c at that joint.

For example if you have an 80 cm mat you ought to give a clearance of 40 cms at least from the face of the load size specified in the software.  If you specified a 30 cms size load you need to provide a clearance of 55 cms at least.

Hope this help

CSI have an article "SAFE Technical Note 1" entitled "How SAFE Calculates Punching Shear For the ACI 318-95 Code".  This article can be downloaded from the CSI web site.
