By the earthquake and the wind against the displacement that occurs in buildings by utilizing the movement of the clip architectural exterior panels can follow the displacement and deformation by preventing the loss of architectural exterior panels to protect life and property.

This study is to solve the structural optimization problem by a quantum-inspired harmony search algorithm. For the optimization, we suggest the mathematical modeling of the plane truss which is possible to minimum weight design. In its model, the cost function is minimum weight and constraint function consists of the stress.
