Abstract

In recent days, tendency of composite materials uses in transmission tower structure is increasing tremendously over conventional zinc galvanized steel materials because of some special advantages. Using the composite materials over conventional materials in the field of large structure construction like transmission tower in large scale, the detail study of the dynamic behavior of structure made up with composite materials is needed. Modal analysis of tower structure made up with composite materials has been reported few or all most nil in the literature. The present study has taken up the challenge for the modal analysis of the present design approach of 132kV double circuit tower made up with composite material like Carbon fiber epoxy (thermoset). The results found for first six modes of vibration using subspace iteration method. The results are compared with the results obtained by typical conventional method, still followed by the industry for erection of such high tower made up with conventional material like zinc galvanized steel. The dynamic design approach incorporating Modal Analysis found to be most competent for stating the dynamic behavior of this tower and further clarify the safety approach of design.
