Seismic resilience enhancement of telecommunication tower: A linear static analysis with viscous damper

Telecommunication towers are always exposed to seismic activity, which jeopardizes essential communication networks both during and after earthquakes. This paper presents an analytical study on the effect of incorporation of viscous dampers on seismic performance of telecommunication towers, keeping linear static analysis into focus. The investigation comprises the evaluation and comparison of base shear, story drift, and story displacement of structures with and without viscous dampers. Generally, base shear-the total horizontal force from seismic action at the base of the tower-is the most important indication of the structural demand. Story displacement and story drift-presently representing the relative movement between two consecutive floors-are studied for determining whether structure flexibility and potential for damage exist. The results show that the addition of viscous dampers effectively reduces story displacement and drift and efficiently dissipates seismic energy while lowering the structure's response. Dampers enhance seismic resilience through the bound deformations and forces that help thereby; therefore, in seismic zones, the towers of telecommunication communication towers operational dependability is extended. This article contributes towards realizing improvement in structures for the telecommunication industry in a safer and more functional condition during earthquakes.
