In this paper, the structural optimization of high-rise guyed tower is carried out for wire and column schemes. The schemes are compared from four wires eight wires, width column, uniform cross-section variable etc. And single-column with recommended tower. Through full-scale test study tower, safety feasibility engineering application verified. According to technical economic analysis traditio...
Avian mortality at communication towers in the continental United States and Canada is an issue of pressing conservation concern. Previous estimates of this mortality have been based on limited data and have not included Canada. We compiled a database of communication towers in the continental United States and Canada and estimated avian mortality by tower with a regression relating avian morta...
Guyed tower is a compliant offshore platform used for drilling and extraction of oil in deep water. This platform has a flexible body and needs proper mooring system to control the deck movements. In present study this platform is analyzed in frequency domain due to irregular waves. The exiting force extracted from Pierson Moskovits spectrum using Morrison Equation. Modeling of moorings is diff...
A finite element solution based on equevalent elements is proposed for the static and dynamic analysis of tallhigh tensioned cable antennas. To reduce high number of degrees of freedom in space frame body of a structure, a simple equivalent beam element is defined for each simulative substructure. This numerical procedure is applicable to analyze complex three dimensional assemblies of substruc...
