The aim of this study is to present the optimization of double-layer barrel vault structures taking into account the stresses and buckling of compression structural members and nodal displacements as a constraint. The buckling is calculated according to the ASD-AISC. In the optimization process a new proposed algorithm named Rao-1 is preferred. The finite element analysis of barrel vault structures is carried out by using applicable programming interface properties of SAP2000 program. The MATLAB programming is used to data transfer from the SAP2000 for sending design variables and getting the stresses and nodal displacement of the structure analysis.
