George Shattuck Morison (1842–1903) was one of the major contributors to the development of modern bridge engineering practice. His career spanned the era from design by empirical “rules of thumb” to the use of mathematical analysis techniques. Morison pioneered innovations in bridge engineering practice, including the introduction of materials testing and inspection, the development of design and construction specifications, and production of project reports. His major bridges included many crossings of the Missouri River, the great cantilever railroad bridge at Memphis, Tenn., and the Boone, Iowa viaduct. Morison served as President of the American Society of Civil Engineers and was an influential member of the Isthmian Canal Commission, which selected the location of the Panama Canal. 相似文献

Stonecutters Bridge is the second longest cable-stayed bridge in the world and the first major bridge with a twin-box girder superstructure. It has a number of innovative structural features which made the construction of the bridge a significant challenge. This paper describes the fabrication and erection procedures for the bridge towers and the main span superstructure. These were developed in close interaction between the contractor and his construction engineering consultant to ensure a safe and effective construction. A stage-by-stage analysis was set up to model every step of the main span erection. The results were first used in the verification analyses to establish the adequacy of the permanent works throughout construction. In parallel, extensive wind tunnel testing as well as numerical analyses were performed to ascertain the effects of typhoon wind loads on the structure. The structural deformations predicted by the erection analysis were incorporated into a comprehensive geometric control procedure. This paper describes the construction methodologies developed and the related engineering input. It outlines studies undertaken to achieve an effective construction, ensure structural adequacy of all erection stages, ascertain an acceptable aerodynamic performance of the bridge, and exercise full control over the bridge geometry throughout erection. 相似文献
