摘　　要：以预应力拱架结构为研究对象,运用反应谱法和时程分析法计算了结构在地震作用下的响应,并与相应的静内力作了比较。结果表明,在预应力拱架结构的抗震研究中,需同时考虑水平和竖向地震作用。总结了结构地震响应的规律,为抗震设计提供有利依据。In this paper, the prestressed-arch structures（STRARCH） is studied. The response spectrum and timehistory methods are applied to its dynamic response analyses. By comparing the dynamic results with corresponding static ones, the rules of dynamic response are generalized. Some results are indicated that horizontal and vertical seismic force must simultaneously be considered in the seismic study and design of the prestressed-arch structures. The results in the paper will provide the valuable references for the anti-seismic analysis of the structures.
