A SEISMICITY OF PARKING TOWERS CONTAINING MOVABLE MASSES

本文研究了停机楼及与其相连的住宅楼的抗震性能。特别是对通过滑动弹簧与建筑物相连的停车塔的结构进行了说明，并考察了它们在地震发生时的动力响应。虽然停车塔是柔性的，建筑物是非柔性的，但它们在地震反应中避免了共振，表现出很好的抗震性能。这是由于当结构接近共振状态时，各楼层上的活动质量开始滑动，滑动弹簧进行减振，从而导致停放塔与建筑物的连接结构比未连接的建筑物或停放塔具有更强的抗震性能

This study deals with aseismatic characteristics of parking towers and apartment buildings which are connected with parking tower. Especially it is remarked the structures of the type of parking towers which are linked to building by slide-springs, and examined how dynamically they response when an earthquake occurs. Although parking towers are flexible and buildings are non-flexible, they avoid resonance and show aseismicity quite well as they respond to earthquake. This is caused by the fact that when the structure approach to a state of resonance, movable masses on each floor begin to slide and slide-springs carry out reducing resonance.It is resulted that the linked structures of parking tower and building by slide springs are more aseismatic characters than non-linked buildings or parking tower
