DEVELOPING STRUCTURAL AND COMMUNICATIONAL FRAGILITY CURVES FOR MONOPOLE TOWER WITH CONSIDERING SOIL STRUCTURE INTERACTION

Communications and its sensitive components are a key element among all other group of lifelines such as Electric power networks, transportation networks, pipelines, traffic, etc. it has been learned from the past earthquakes that the Existence of communication especially cellphone towers could facilitate the rescue and relief operation on post- earthquakes risk management process, this leads to saving more lives which is very vital. This study focuses on the reliability assessment and seismic performance of monopole tower subjected to earthquake loadings by probabilistic approach and Considering Soil Structure Interaction (SSI). The vulnerabilities of these towers are expressed with the development of fragility curves, which provide the probability of exceeding a prescribed level of damage for a wide range of ground motion intensities. By performing a sets of nonlinear incremental dynamics analyzes (IDA) on convenient communicational tower (24m height Self-Support tower) is tried to derive fragility curve for structural and communicational performance separately. The primary contribution of this research is that this study is the first of its kind that develops fragility curves for monopole tower.
