The present paper discusses the seismic response characteristics and equivalent static seismic forces of large span arches. Firstly, 81 sets of steel arches supported by steel columns are designed using the four geometric parameters: span, height of the substructure, half open angle and ratio of span to depth. Then the eigenvalue and earthquake response analyses are carried out to investigate the dynamic behavior of the structures. According to the numerical results, the participation factors can be adopted as the criteria for deciding if the vibration characteristics of this kind structure is dominated by the first mode or not.Lastly, an estimating method of the equivalent static seismic forces based on the response spectrum technique is proposed and followed by one practical method about which the accuracy and scope of the applications are analyzed.
