REFCALCULATIONSOUTPUTInput Data:Ultimate Load (Fv)=711kNLoad as a UDL (kN/m)=592.5kN/mNib Width (Projection)=325mmNib Depth (D)=500mmDistance to Load (av)=325mmGrade of Concrete (fcu)=45N/mm2Grade of Steel (fy)=460N/mm2Grade of Shear Steel (fvy)=460N/mm2Cover=25mmMain Bar Diameter()=16mmLink Diameter=10mm
Nib Geometry:BS 8110Bearing Strength(0.4*fcu)=18N/mm2Cl 5.2.3.4Effective Bearing length is least of a,b,ca.Bearing Length=1200mmb.One half bearing length + 100=700mmc.=600mm
Effective Bearing Length=600mm
Net Bearing Width=(Ultimate Support Reaction)/(Bearing Length x 0.4fcu)>=40mm=65.8333333333mm
Net Bearing Width=65.8333333333mm
Allowance for spalling=25mmAllowance for inaccuracies=25mmNominal Bearing width=115.8333333333mmRequired Nib Projection=nominal bearing width+25=140.8333333333mm
