| 摘 要： | 对比现有国内外钢桥设计规范中计算钢桥面板有效宽度的计算方法和公式。分析普通铁路钢桁梁桥纵横梁明桥面系和高速铁路钢桁梁桥正交异性整体钢桥面系传力途径和受力特点的不同。得出现有规范中的公式只能计算平面受弯构件，如简支梁和连续梁的有效宽度，不适用于正交异性整体钢桥面系杆件的结论。在上述基础上，提出了计算正交异性整体钢桥面板有效宽度的原则。

| Abstract: | The calculation method and formulae of effective width of steel deck in current steel bridge design codes at home and abroad are compared and studied. The differences of transferring routes of loads and mechanical behaviors between the longitudinal-transversal beams steel deck system of normal steel truss bridge and the orthotropic monolithic steel deck system of high-speed railway are compared and analyzed. A conclusion is drawn that the formulae in current steel bridge design codes can only be used to cal... |
