ANALYSIS OF DYNAMIC CHARACTERISTICS OF CABLE-SUPPORTED CONCRETE-FILLED STEEL TUBE ARCH BRIDGE

摘要：

According to a reality cable-Supported concretefilled steel tube arch bridge (Tianzishan Bridge),a 3-D finite element model is established. The dynamic characteristics of the bridge are calculated. These results are in accord with the actual results by comparing the measured dynamic characteristics of the bridge. By considering the impaction of the different parameters including the variation of the cable tension and elastic modulus on the natural vibration of the bridge,the cable tension plays an important role in the alteration of structural dynamic property of the cable-supported concrete-filled steel tube arch bridge.
