Abstract: Under the presupposition of stable abutment, this paper deals with trussed-arch bridge in which dynamic properties, coupling of vibration types, support conditions as well as vertical component in the analysis of seismic response are fully discussed. Comparisons are also made between static and dynamic analysis in order to study the vibration resistance of single span reinforced concrete trussed arch bridge. Finally, attention should be paid to the problems closely related to this category of arch bridge in earthquake design.

摘要： 本文在假定桥台稳定的前提下,考虑桁架拱桥的动力特性、振型遇合、支承条件以及地震反应分析中的竖向分量的影响,对其进行静力和动力的分析比较,讨论单跨钢筋混凝土桁架拱桥的抗震性能,进而提出在设计中应予重视的一些问题。
