Abstract

In view of the fact that integrated intelligent tower construction machine which is designed to improve the construction efficiency and quality and operating conditions of bridge towers always withstand various wind loads (especially super typhoons or gusts) so that hidden dangers may exist in their structural safety and reliability, their structural dynamic characteristics analysis of effects of strong winds shall be an essential part in their design stage. For this purpose, Davenport wind speed spectra were used to simulate the extreme pulsating wind loads and their structural dynamic wind-induced responses were investigated by means of the finite element method (FEM) to gain the displacement and stress responses of key nodes and then determine their structural design safety. The results show that: the maximum stress and displacement occur in the upper parts of their frames; and the forces and displacement of their structural dangerous positions are within their corresponding safe ranges. Our analysis results can provide a theoretical reference for application and structural optimization of tower machine.
