碩士 === 國立中興大學 === 土木工程學系所 === 100 === The objective of this thesis is to discuss the stability of a vibrating member, by using the method of Particle Swarm Optimization (PSO) to analyze it under non-conservative force, and to find the relation between its buckling load and natural frequency. There are two conclusions made. Firstly, the method of PSO is suitable for solving structural problems that under the force similar to non-conservative force and efficient for solving non-linear equations. Secondly, the mass of Hydraulic Damper, the direction of force exertion, the vibrating shape of the member and the placement of Hydraulic Damper do affect the member’s buckling load. These factors have to be included in considerations whenever in analyzing or designing.
