Resumen
Failures and collapses of steel truss towers may be caused by various factors, which often occur simultaneously. The evaluation of truss tower reliability when single elements fail constitutes an important research area. It may happen that the failure of a single element of the structure leads to a redistribution of internal forces that results in the exceedance of the capacity of subsequent bars. This brings about the occurrence of a mechanism, i.e., the structure failure. In this paper, the impact of the failure of individual elements on the overall reliability of the tower is analyzed. The literature lacks research using a system approach to complex truss structures. This article describes the original procedure for assessing the reliability of truss towers after the failure of a single element. This method can be used to assess the safety of truss towers with damaged elements.
