【摘要】 为掌握下承式钢管混凝土拱桥的动力响应规律,实施了该桥型的振动台试验,按刚度相似关系,提出了将模型材料单一化的截面刚度转换公式;试验结果分析了不同烈度等级下,拱肋各显著截面的应变反应的状况。更多还原

【Abstract】 In order to master the dynamic response rules of through concrete-filled steel tubular arch bridge,implementation of the shaking table test of this bridge.According to the rigidity similarity relation,put forward section stiffness conversion formula made model materials single,the test results analyzed the stress and strain response situation of each section stiffness under different intensity levels.更多还原
