泼河大桥结构动力特性分析

Research on Structural Dynamic Performance of Pohe Bridge

随着我国首座装配式波形钢腹板PC连续箱梁桥——泼河大桥的建成,该类桥梁日益得到广泛应用,但目前国内外对波形钢腹板PC组合箱梁桥的自振特性尚无明确规范规定。基于泼河大桥的实际设计功能构造特点,采用有限元方法对多箱式连续波形钢腹板PC组合箱梁桥的动力特性进行分析,可为同类结构的计算分析提供参考和依据。

Along with the establishment of Pohe Bridge, which is the first prefabricated wave shape steel celiac board PC continuous trunk girder bridge, this kind of bridge has got widespread application, but there have been no specific regulations about the natural vibration feature of wave steel celiac board PC continuous trunk girder at home and abroad. Based on the design function structural characteristics of Pohe Bridge, the finite element method is used to analyze the dynamic performance of multiple-part continuous wave steel celiac board PC combined trunk girder bridge, which can serve as the reference for the calculation and analysis of similar structure.
