这是一种新的分析细长梁横向稳定性的综合方法。技术使越来越长的大梁得以制造。细长梁存在横向稳定性问题。考虑了主梁从浇筑台过渡到其在桥梁中最终位置的每个阶段。这些条件包括在储存、运输期间，或在施工期间，在桥梁上的各种条件下，使用嵌入或连接的设备从顶部搬运，并从下方支撑。这些建议是罗伯特·马斯特在20世纪90年代进行的开创性研究的结果。2007年，PCI桥梁委员会清楚地看到了解决主梁稳定性问题的必要性。 他们选择了一个专门的团队来制定这些建议。该团队的制作人成员提供了丰富的现场实践经验。该团队与大量设计师从业人员一起，制定了一项行业共识建议实践，提供了计算主梁寿命各个阶段安全系数的方法。这是桥梁设计、制造和施工中所有利益相关者的必备出版物。

This is a new comprehensive methodology to analyze the lateral stability of long slender bridge girders. Technology has enabled the manufacture of increasingly longer girders. Slender girders present a lateral stability concern. Each stage of a girder's transition from the casting bed to its final location in the bridge is considered. These conditions include when handling from the top with embedded or attached devices and supported from below during storage, transit, or in various conditions on the bridge during construction.These recommendations are the result of ground-breaking research conducted by Robert Mast in the 1990s. In 2007, the PCI Committee on Bridges clearly saw the need to address girder stability. They selected a specialized team to develop these recommendations. The producer members of the team have contributed substantial practical field experience. Together with a large number of designer practitioners, the team has developed an industry consensus recommended practice that provides methods to calculate the factors of safety during each of several stages of a girder's life. This is a must have publication for all stakeholders in bridge design, fabrication, and construction.
