PILES WORKING LOADS

TPC RC Square Piles maximum allowable working loads are calculated according to BS 8004:1986

Maximum Allowable Working Load = 0.25 fcu x Ac + fs x As

Where

fcu

=

characteristic cube strength of concrete at 28 days

 

 

=

30 or 45 N/mm²

 

 

 

Ac  = area of concrete

 

 

 

fs = 175 N/mm² for high yield reinforcement

 

 

 

As = cross sectional area of longitudinal steel
