Internal Force Distribution of Nielsen Style X-Style Arch Bridge
-
摘要: 为了研究尼尔森体系提篮式系杆拱桥在各种荷载(分布力、集中力、活载)作用下内力分布规律,对一座 提篮式系杆拱桥进行了计算分析,并与平行吊杆及平行拱肋拱作了比较,在此基础上结合模型试验进行验证研 究。结果表明:模型设计合理可行,能准确反映结构的受力特征。Abstract: A study is made on the distribution regularities of internal forces of Nielsen style concrete-filled steel tubular tied arch bridges under different loads such as distributed force, concentrated force and live load. The results are compared to those of Lohse style arch and parallel rib arch. Model tests are carried out to verify the effectiveness of the theoretical computation. The results show that the design scheme of the model is reasonable and feasible, and the experimental results obtained on the model can accurately reflect the mechanical properties of Nielsen style concrete-filled steel tubular tied arch bridges.
