Abstract

Practical approach to optimum design of steel tubular slip-joint power transmission poles M. ~icleli' & W. ~ a s s a r ' I Civil Engineering and Construction Department, Bradley University, USA. Abstract Steel tubular poles are employed in large numbers when used for power transmission and consequently their most economical design is desirable. The pole weight affects the overall cost of a system of steel tubular pole structures considering the cumulative effects of material, manufacturing, transportation and erection costs. Therefore, an optimal design may be achieved by designing the lightest possible slip-joint pole which fulfills the geometric and limit states criteria under specified loading conditions. In this research, a computer-aided approach, for the optimum design of steel tubular slip-joint poles is developed. The pole weight is optimized to satisfy the specified geometric limits and limit states design criteria. The optimization procedure uses a simple algorithm to vary the pole d
