中文摘要：
目前拱支结构在大跨度空间结构领域得到广泛应用.弦支穹顶叠合拱结构作为一种典型的拱支结构形式,已被山东茌平体育馆所采用,跨度达到196m.本文基于多点激励下的地震响应时程分析,研究了大跨度弦支穹顶叠合拱结构的行波效应.分析结果显示：当地震波速分别为300m/s、800m/s、1200m/s时,相应的地震行波效应系数分别为10.30、4.78、3.56,由此可见,对于大跨度弦支穹顶叠合拱而言,其行波效应较为显著,建议设计时适当考虑.
英文摘要：
The arch supported structures are widely adopted in large span spatial structures. The suspen- dome with stacked arched structures is a typical arch supported structure, which is adopted in Chiping Gymnasium. The span of the suspend-dome with stacked arch structures is up to 196 m. Therefore, the multiple support earthquake excitation time history analysis is carried out to investigate the wave traveling effect on the suspend-dome with stacked arch structures. The analysis results show that the wave traveling effect is remarkable and the maximal wave traveling effect factor under V= 300m/s, V= 800m/s and V=1200m/s are 10.30, 4. 87 and 3.56 respectively. It proves the wave traveling effect is significant on the suspen-dome with stacked arch structure and slould be considered in design.
