Abstract

Self-supporting towers are structures commonly used in the broadcasting industry and as antennas for television and telephony. These structures are sensitive to the dynamic actions of wind and earthquake due to their structural characteristics of low damping and flexibility. The correct identification of the modal characteristics of the self-supporting towers has a great importance for the determination of the dynamic components of the wind and earthquake loads; as well as for the models updating and the identification of damages from full-scale measurements. In this work, a characterization of the dynamic behavior of four self-supporting towers of triangular section is carried out by determining their natural periods, modal shapes and the percentage of mass participation. In addition, a sensitivity study is carried out for the placement of accelerometers in order to carry out subsequent full-scale measurements of these structures.
