| 摘 要： | 目前对人行桥、楼盖的振动都有相关的舒适度指标规范,但对大跨度舞台的振动舒适度指标尚无文献报道,用有限元软件MIDAS对大跨度舞台进行竖向动力分析,根据所得的动力响应时程来进行舒适度评价.通过借鉴人行天桥舒适度的评价指标,对舞台的舒适度进行评价.得出表演人数控制在一定范围内时,舞台舒适度能得到保证.根据最终的评价结果再次...

| Abstract: | The dynamic response of loads created by dancers to the large-span stage should not be neglected.Generally the safety of stage structure is guaranteed;if the peak acceleration of stage vibration is too big,the service performance of the stage will be influenced.At present,the vibrations of footbridges and floors are standardized in every country by corresponding comfort index specification,but that of large-span stage is not still formulated.Through the dynamic analysis of large-span stage structure under s... |
