The Jiujiang Yangtze River Bridge is a bolted and welded steel structure, whose main componentsare made of 15MnVN_q bridge steel of high tenacity, the maximum plate thickness being 56mm. Dueto the previous improper selection of the solder wire, the toughness of the welded seams was ratherpoor as compared with that of the base metal. In this peper, by applying the research method of frac-ture mechanics, a new H04M_nM_oE solder wire is developed, which greatly increase the holding powerof the welded seams, making...

The Jiujiang Yangtze River Bridge is a bolted and welded steel structure, whose main componentsare made of 15MnVN_q bridge steel of high tenacity, the maximum plate thickness being 56mm. Dueto the previous improper selection of the solder wire, the toughness of the welded seams was ratherpoor as compared with that of the base metal. In this peper, by applying the research method of frac-ture mechanics, a new H04M_nM_oE solder wire is developed, which greatly increase the holding powerof the welded seams, making them match with the base metal fiarly well. This settles the long-stand-ing argument about the strength of the Jiujiang bridge's welded seams.

九江长江大桥是一座大型栓焊钢桥,桥梁主要受力杆件选用15M_nVN_q钢制造,最大厚度为56mm。钢材本身有良好的韧性。由于原选定的焊丝不尽合理,焊缝的韧性较差,不能与基材配套。本文引用断裂力学的研究方法,选定了H04M_nM_oE焊丝,使焊缝的韧性大幅度提高,焊接接头的韧性与基材的韧性相匹配。这一研究成果解决了长期存在的关于九江桥焊缝韧性的争论。

To investigate the fatigue behavior of deck constrction of deck truss,threereduced scale specimens are tested;stress range and type of detail were the two test parameters.The major factors governing fatigue strength are the applied stress range,the numberof cycles,and type of detail.It is found that fatigue cracks commence at some initial discontinuity in the weldment or at the weld periphery,and grow perpendicular to the appliedstresses.It is also found that fatigue strength is very lower without tighfly withstood...

本文对单线铁路上承式栓焊桁梁桥面系纵、横梁的疲劳行为进行了综合分析和研究.通过模型试验和理论分析,探索桥面系结构及其连接的受力状况和应力分析。明确桥面系在不同荷载作用下,鱼形板的受力状况,进一步研究影响其结构疲劳的主要因素,观察疲劳裂纹产生的部位,分析造成结构疲劳和断裂的成因;指出纵梁可按弹性支承连续梁计算;纵、横梁连接处纵梁腹板间隙处将产生面外变形,此面外变形与焊接残余应力、局部焊接缺陷共同作用,容易造成焊趾处开裂;由于构造细节的不同时结构耐劳强度会产生较大影响.试验表明,影响疲劳强度的主要因素是作用应力的脉动量、受力次数和细节式样。提出改进桥面系连接构造的建议,供设计时参考。

This paper describes the effect of welding on behavior of beam-to-Column connection with HSB at web and welds at flanges.By means of FEM of bolt-connected plates in consideration of force transfer by friction,the stress distribution of this kind of connection was obtained.Besides,the temperature distribution at joint panel,changes in pretension of HSB and panel deformation was measured.The paper ended with some constructional proposal in view of the effect on HSB's pretension.
