【Abstract】 Based on the characteristics of a collapsed mobile-communication tower, its load-bearing capacity was analyzed by the finite element method, and material tests for six specimens truncated from the collapsed tower were carried out. The analysis and tests showed that the improper design of the sections and the joints was the main cause of the accident, and some suggestions about tower′s designning were given.更多还原
