The telecommunication masts are considered today as one of the basic infrastructures in the human societies. Due to their vital role, the preservation of these structures during natural disasters, such as a severe earthquake, is of utmost priority and hence their seismic performance should be properly evaluated. The researchers in their studies have considered the effects of wind and earthquake-induced loads mostly on the trussed steel masts of triangular cross sections. The telecommunication

Longitudinal loadings may be the result of weather-related events, failure of an adjacent structure and must be resisted to prevent cascading failures of the support structures in the line. For this reason, longitudinal loadings are sometimes referred to as "Anti cascading" failure containment" or "Security" loads.
