Major Brace-to-chord welds请问是什么焊缝?(转)? 帮害羞的lz把他的answer引过来:p “找到一句话:current practice is to connect the brace to the chord with double sided welds. this reduces the possibility of fatigue cracks initiating at the weld ... major可翻译为“重要”、“主要”。brace-to-chord 可理解为两者结合处。至于brace与chord怎么翻译,还需要高人来解答。 题外话:我感觉紫龙兄你的这个问题更偏向于桥梁结构,而非管道。 ------------------------------------------------------------------------- chord我查到了可能是chord member(弦杆)。 http:///indu/096/0953641f049.htm compressive chord member 受压弦杆 1. in some truss structures,such as the roof truss undergoing heavy upward wind load,or the truss on both sides of a footbridge connecting different buildings,the service conditions do not allow us to place lateral support for the compressive chord members. 在一些受较大向上风载的屋架或连接不同单体建筑步行桥的两侧桁架等结构中,由于受到使用条件限制而无法为受压弦杆设置平面外的支撑系统,因此这些结构中受压弦杆在平面外的稳定问题就显得格外突出。”查看更多
