Thin square plates of an idealized model and of real concrete were
studied and compared under uniaxial and biaxial short-term compressive
stress. Formation and propagation of microcracks of the concrete
model were observed directly during loading with x-ray photographs.
Strength, deformational behavior, and fracture of concrete under
uniaxial and biaxial compression were observed.
Microcracking observations indicate that a main cause of the increase
in both strength and stiffness in biaxial compression is the confinement
of potential microcracking in the presence of biaxial compression.
The modes of failure of concrete suggest that tensile deformation
is vital in the failure mechanism of concrete.
A general stress-strain relation for concrete in uniaxial and biaxial
compression is proposed. In addition, a simple equation is proposed
to predict the increase in strength of concrete when it is subjected
to biaxial compression.
