钢管混凝土拱桥动力特性分析

he model of concrete-filled steel tube arch bridge have some simplify simulation ways, But it have not studied yet that whether each simulation way can reflect the true dynamic characteristic of the arch bridge and how serious To influence the dynamic characteristic. The book will set up three kinds of different finite element models and analyze whether the different finite element models can simulation the dynamic characteristic of the concrete-filled steel tube arch bridge similarly.
