INFLUENCE ANALYSES OF BOUNDARY STIFFNESS ON WIND OSCILLATIDN RESPONSE OF CABLE NETWORKS

In this paper, according to the characteristic of cooperation and interaction between the cables and boundary supporting structures,applying the random vibration theory and taking the three-dimensional interference of wind into account, the influence law of boundary constructional element stiffness on the wind oscillation response of cable networks have been analyzed.The analysis indicates that the critical stiffness ratio is a key parameter in calculating the dynamic response of cable network structures.
