3 The following tables provide the total ultimate limit state design resistance for the configurations. All tables are based upon: correct setting (See setting instruction) non-cracked concrete fc,cyl = 32 MPa minimum base material thickness, as specified in the table below effective anchorage depth (heff) does not equal to nominal anchorage (hnom) and borehole depths (h1) in case of stud anchors.
