| Abstract: | Taking a new type arch bridge as the research subject, the calculating model of main stay bar is established in this paper. The inherent frequency of main stay bar is solved. The wind velocity and its critical value in each spot of main stay bar are also confirmed. By programming the structural maximum displacement response in resonance state is calculated. So the maximum displacement response and its occurring position of main stay bar in the vortex-stimulated resonance state caused by wind can be obtained... |
