| 摘要： | The objective of this project is to understand the plausible reason(s) why the southeastern vertical strut of the Paseo Suspension Bridge in Kansas City, MO, fractured on January 22, 2003 after nearly 50 years of service. The load on the strut will be estimated from three sources: the payload used on the bridge deck during repairing to reposition the raised deck, the calculation of load rating from previous inspections and from the recent emergency design, and thermal effects on the failed strut as a result of a frozen pinned condition. The fatigue strength and fracture resistance will be determined with a series of characterization tests of the materials from the failed strut. |
