A laboratory investigation was conducted to study the effect on strength of several multiaxial stress combinations related to shrinkage, temperature cracking, gravity, hydraulic loading, and foundation movement in a massive concrete structure. Based on the results of this investigation, the following conclusions appear warranted a the strength of concrete in biaxial compression is at least as great as it is in uniaxial compression b for the purposes of most design and analysis problems, use of an idealized interaction diagram for biaxial stresses appears feasible c most design and analysis conditions involving biaxial compression plus uniaxial tension can be defined by a straight-line relationship between the points of maximum biaxial compression and uniaxial tension and d unusually large induced tensile strains 2000 millionths may result from a condition of biaxial compression.
