摘要: Steel-free deck design is a relatively new approach to bridge construction. Several steel-free bridges constructed in Canada exhibited satisfactory behaviour immediately after However, the long-term health of many these structures has not been investigated. Significant cracking observed only few years service. Long-term structural monitoring key determining their performance and future adoption this technology. Structural data were obtained from Crowchild Trail Bridge during its first seven Field included ambient vibration tests, static dynamic load crack mapping. Despite significant amounts cracks concrete barriers, overall remained consistent. Future designs should consider control to...
