I am trying to design my Anchor Bolts for seismic loading, But I am getting an error message statement " THE CURRENT SEISMIC REGULATION (EN1992-4) DOES NOT COVER STANDOFF WITH GROUT APPLICATIONS, WHERE T>=0.5d", does this means that there can't be a gap b/w base plate and concrete slab in case of seismic design ? also is t the thickness of grout and d the dia of the anchor bolt ?, also what are the additional provisions to be considered in case of Seismic design , i.e. parameters that we need to define in PROFIS additional to Static design, how to select the seismic parameters in PROFIS?
Hi Prashant, 0.5*d holds only when we are checking the shear capacity without lever arm , in case we have checked for shear capacity with lever arm(which accounts for additional moment acting on the bolts) we can we can provide grout thickness up to 40mm.
Hello Ms. Surabhi, Yes you can do so in case of Anchor design under static forces but not incase of Seismic forces as EN 1992-4 does not cover the standoff with grout applications, where t>=0.5d under seismic anchor design conditions.
