Abstract : A new method for optimal design of structures is presented. The structure is subjected to multiple loading conditions and behavioral constraints on nodal displacements, element stresses and constraints on member sizes. This new method is based on the Kuhn-tucker conditions, in which the gradients of active constraints are expressed through Taylor series expansion in terms of design variable so that a new design point can be generated. Recursion formulas for the iteration determination of the design variables are thus derived.
