Moment redistribution can play an important role in making the design of reinforced concrete (RC) structures
more realistic and economical. In this paper, a new comprehensive formula has been proposed that considers
four input parameters that are thought to influence moment redistribution the most in statically indeterminate
RC beams using gene expression programming (GEP). For this reason, an experimental database of 108 data
points was collected from experimental studies in the literature to predict the moment redistribution of the RC
beams using genetic programming. All of these collected data points belong to two-span RC continuous beams.
The results of the GEP formulation were statistically compared with the experimental results obtained from the
literature and the results from the equations provided by the current design code provisions. The results of the
comparison revealed that the proposed GEP-based formulation has the best performance and accuracy among the
proposed models. Moreover, the sensitivity analysis and parametric study were also carried out to evaluate the
most critical parameters affecting on moment redistribution of RC continuous beams.
