Some applications of Convex-Subspace Single Linkage Method (CSSL method) to a multi-peaked structural optimization problem are described. CSSL method is one of global optimization methods, which use a gradient component of an objective function. This method has two main processes. One is a local optimizing process and the other is a clustering process. In this paper, one mathematical example and two examples of a structural optimization are illustrated. Solving the mathematical example, a validity and effectiveness of the method is investigated. As structural optimization problems, a layout design problem and a fiber orientation design problem are solved. The layout design problem is to optimize a location of inserted reinforcement for a beam structure. THe fiber orientation design problem is to optimize a fiber orientation of a laminated composite plate for an eigenfrequency problem. All of these are a global optimization problem. Especially, for the fiber orientation design problem, optimization using CSSL method and NN approximation is attempted, and a practicality of the method is investigated.
