counterfort retaining wall design
counterfort retaining wall design
(OP)
Hi All,
Does anyone out there have any information or examples for the design of a counterfort retaining wall? Wall height is approx. 16 ft with 15 ft of retained soil. Toe has approx 8 ft of soil on it. Site has some constraints which won't allow me to raise the base. I've done cantilevered walls in the past, but I'm not sure how to go about accounting for the counterforts in the stem design. Any help would be greatly appreciated.

Calculate the moments at intervals down the height of the wall to determine reinforcement required at various depths. The facing spannign between counterforts can be considered as the flange of a T-Beam providing sufficient fixity between counterfort and wall facing. The facing is designed for horizontal bending (usually iun upper middle and lower thirds to economise on reinforcement.
External stability for base sizing is designed as per standard CIP wall.
Hope this helps.
