【摘要】 本文建立了钢桁梁桥的平面桁架计算模型与空间刚架计算模型，运用于空间迭代法求得竖向、横向基本周期，以丰准线黄河大桥为例提出了预测铜桁梁桥悬拼过程中人体对振动感觉的分析方法，这一方法可用于评价、改进钢桁梁桥的悬拼方案，指导安全施工。更多还原

【Abstract】 h this paper,it is established the calculating of planar truss and spaceframe for steel truss bridge,It has calculated the vertical and transversal basic period by thesubspace iteration method.It raises an analytic method of man sensation for vibration of steeltruss bridge in suspending installation,for instence the Yellow River Bridge on the Railwayof FengZhun to ZhunGeEr.So as to evaluate and improve sheme of suspending installationand guide constraction more safely.更多还原
