【摘要】 以一新月形异型钢管混凝土拱桥为研究对象,对其动力模型建立的方法、思路进行了探讨.基于不同的离散思想,建立起鱼骨模式、改进鱼骨模式、梁格模式等3种不同的计算模式进行了分析,并对其计算结果进行了分析比较,由此论证了此类桥梁结构简化为传统鱼骨模式的合理性.更多还原

【Abstract】 Taking a crescent special-shape concrete filled steel tube arch bridge as the research object,it discussed the methods and ideas of building dynamic model.Based on different discrete thought,it built up and analyzed three different computing models of the fishbone model,and improved fishbone model and beam grillage model,it analyzed and compared the calculation results,that proved the rationality that such kind of bridge structure is simplified to be the traditional fishbone model.更多还原
