The development of QEA(Quantum-inspired Evolution Algorithm) and their engineering-problem applications have emerged as one of the most interesting research topics. These algorithms find optimal values with the operators such as quantum-gate by using quantum-bit superposed basically by zero and one. In this process, the balance between the two features of exploration and exploitation can be kept easily. So, this paper is to propose an optimum design program for truss system based on QEA and 17 bar plane truss model is adopted as numerical example.

Large span roof structures require an analysis of their static and dynamic behavior depending on the physical parameters defining the structures. Therefore, it is highly desirable to estimate the parameters from observations of the system. However, the study of the behavior of such structures shows the existence of critical parameters. A small change in such parameters causes a significant change in the motion behavior. In this paper we study the parameter identification problem for shallow sinusoidal arches considering damping effect.

With the advent of quantum computer, the development of quantum-inspired search algorithms and their engineering-problem applications have emerged as one of the most interesting research topics. These algorithms find optimal values with the operators such as quantum-gate by using quantum-bit superposed basically by zero and one. In this process, the balance between the two features of exploration and exploitation can be kept easily. So, this paper is to propose an optimum design program for plane truss structures based on quantum-inspired evolution algorithm. The objective function consists of the weight of the structures, and the design variables are the cross-section areas. 10 bar plane truss model is adopted as numerical example.

At this paper two types of initial shapes and loads are introduced, and we assume that the initial shapes and loads are defined by sinusoidal functions. Under this assumption the asymptotical stability of the solutions is established by investigating the eigenvalues of the characteristic polynomial of the system. The exact solution is obtained when the initial shape and the load are given by a linear combination of sinusoidal functions. The asymptotic stability of the arch is completely analysed.

There is a limit to the representation of finite element analysis modeling of the pure shear of corrugated plate. However, if the shear force is applied to the corrugated plate, the set of appropriate boundary can be obtained to the nearest theory value. In this study compared Shear buckling strength about each boundary condition with the plate shear theory. And then each boundary condition applied to sinusoidal corrugated plate, evaluate convergence of the minimum shear buckling strength of each boundary condition and shear buckling flow was observed through shear buckling mode shape.
