Newnumericalmodels are developed to predict the strength of concrete undermultiaxial compression using linear
genetic programming (LGP). The models are established based on a comprehensive database obtained from
the literature. To verify the applicability of the derived models, they are employed to estimate the strength of
parts of the test results that are not included in the modeling process. The external validation of the model is further
verified using several statistical criteria. The results obtained by the proposed models are much better than
those provided by several models found in the literature. The LGP-based equations are remarkably straightforward
and useful for pre-design applications.
