PILES WORKING LOADS

TPC PC Square Piles maximum axial working loads are calculated in compliance to BS 8004:1986

Maximum Axial Working Load = (0.25fcu – fce)Ac

Where

fcu

=

characteristic cube strength of concrete at 28 days

 

 

=

40 N/mm² or 60N/mm²

 

 

 

Ac  = area of concrete

 

 

 

fce = effective prestress of concrete
