Optimization In Structural Design Of Polygon Plug-in Steel Poles

Multi-rhombus Plug-in Steel Tube is a new type of power transmission tower. In this thesis, optimization in structure of this type of tower was investigated. By analyzing structure mathematical model which has solved by optimization method of mixed discrete variable (MDOD) of steel pole was built., and corresponding computer program TowOpt worked out to optimize a steel tube .The conclusion that can be referenced by engineering design. At the same time this thesis also discussed plug-in problem and deduced a new method of computing length of plug-in section. Tian Zhibing(Mechanics) Directed bProf. Wang Zangzhu...
