正交异性钢桥面板以其自重轻、质量控制方便等优点逐渐在大跨度桥梁中得到广泛应用，但其连接部位的应力集中问题也是影响结构设计的重要因素之一。因此，研究正交异性钢桥面板的结构性能和检查细节的应力分布，以开发一个最佳的连接细节是必要的。本文通过分析研究和试验验证，确定了横梁高度、厚度、剪切面积、隔板效率和形状等参数的最佳值，从而防止了疲劳裂纹的产生。
Orthotropic steel decks gradually come into general use in long span bridges due to various advantages such as dead weight reduction, easy quality control, and so on. On the other hand, stress concentration is often observed near the connection details, which may lead to fatigue problems and govern the design of the structure. Therefore, researches to understand the structural behaviors and examine stress distribution of details in orthotropic steel decks are required in order to develop an optimal connection detail. In this paper, optimal parameters regarding height, thickness and shear area of a cross-beam and efficiency and shapes of bulkhead plates are characterized by analytical studies and verified by experiments, so that fatigue cracks could be prevented.
