The main goal of this research is determination of optimum shape concrete ogee arch under earthquake loads by Gene express programming. In this paper, samples of semi-circular, obtuse angel, four- centered pointed, Tudor, ogee, equilateral, catenaries, lancet and four-centered ogee arch are modeled. Then they are analyzed and optimized under acceleration–time components of Elcentro earthquake. For arch response optimization, the results were used in Gene express programming computational model. Then using provided rules for modeling, the mentioned ogee arch are analyzed and optimized. The results of error range and time of analysis in Gene express programming model and FEM software compared. Finally comparing the results of GEP (Gene express programming) method and FEM (Finite Element Method) method, shows that although precision is less in GEP method, but the time of analysis and optimization is so much smaller in it.
