Behavior under Multiaxial Stresses

Concrete under Triaxial Stresses

• The strength and ductility of concrete are greatly increased

under conditions of triaxial compression.

• Richart, F. E. et al. (1928) found the following relationship

for concrete cylinder loaded axially to failure while

subjected to confining fluid pressure.


 = f + 1 . 4 f l
f
cc
c

Where f’ = Confined compressive strength
cc

f’ = Unconfined compressive strength
c
f = Lateral confining pressure
l
