2005年度IStructE 结构奖中Greenside Place桥

分类: 结构
   There are clever bridges, smart bridges, fun bridges and special bridges. Greenside Place is a rare bridge, it's all of them without contrivance or self-indulgence. 48m long, curved in plan and helical in structural form. Deceptively simple yet elegant in execution - a credit to Engineer and Specialist Steelwork Contractor.
   有许多座精巧、漂亮、有趣和特别的桥, Greenside Place就是这样一座杰出的桥, 它没有任何发明创造或自我放纵的地方。 48 m 长的, 在平面中弯曲如螺旋状的结构的形式。看似简单但很完美的制造——这项荣誉授予工程师和Specialist Steelwork Contractor承包商
   The bridge functions as a link over a main arterial route into the heart of historic Edinburgh, between a multi-storey car park and the St James shopping centre. Formed from a series of interlocking helixes it presented significant analytical and construction challenges. Analysis took into account locked in stresses due to the tube bending processes and likely fabrication tolerances. Bridge dynamics analysis showed excellent modes of vibration and pedestrian induced vibration analysis showed accelerations well below perceptible thresholds. Of particular note is the attention to detail demonstrated by clean lines and clever incorporation of glass at roof and handrail levels.
   这座桥是连接进入古老爱丁堡中心的主要干线,它在多层停车场和圣詹姆士购物中心之间.它是由一系列带有重要分析意义和建筑挑战的联锁螺旋状物体组成。分析注重由于钢管弯曲过程中可能产生制造误差,动力分析显示有很好的振动模态,步行者在桥上行走带来的振动感远小于人体可感觉到限值。简洁的轮廓和屋顶的玻璃和水平扶手精巧的结合都反映对细节的重视。
   Fabrication involved compromise within the analytical tolerances expected, and the whole bridge was fully butt welded in a workshop jig then cut into five pieces for transportation to site. Erected and site welded over the main road during three Sunday road closures it was ready for fit-out without further disruption to traffic. Clearly such a collaboration between Engineer and Steelworker has ensured that Greenside Place Bridge deserves the Institution's Special Award.
   装配需要控制在期望公差范围之内,整个桥在工厂装配架上焊接并分成五段运输到现场对接焊接,而且在主要马路上空安装和焊接完成站用了3个星期日的道路关闭,由于准备充分而没有进一步中断交通。象如此在工程师和Steelworker之间的合作已足以使得Greenside Place 桥该得到协会的特别奖。
Judges' comments
"Demonstration of excellent collaboration between Engineer and Steelworker."
"A structure to make children want to be Engineers, it's fun!"
评语:
“一个工程师和制造商合作的典范”
“一个能让儿童想成为工程师的结构,太妙了"
