Optimal retrofit of moment resisting frames using braces accounting for geometric nonlinearity and serviceability conditions

•Three optimal retrofit approaches of existing structures with braces are proposed.•The approaches incorporate elastic buckling using 2nd-order geometric nonlinearity.•The optimization takes the form as a mixed integer nonlinear programming problem.•The binary constraints eliminate brace members wit...
