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

本文研究了停车楼及与停车楼相连的住宅楼的抗震特性。特别是它是由滑动弹簧连接到建筑物的停车塔的类型的结构，并检查如何动态响应时，地震发生。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。这是由于当结构接近共振状态时，各层可动质量开始滑动，滑动弹簧起到减震作用，从而使停车楼与建筑物通过滑动弹簧连接的结构比不连接的建筑物或停车楼具有更好的抗震性能
