| 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.

| Abstract: | 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. |
