中文摘要：
为了给地震差距的合理宽度阻止在地面期间的结构的跳，打手势，邻近的结构的最大的相对排水量在这份报纸被学习。可以在最大的相对排水量上有效果的因素被讨论。至于 multi-degree-of-freedom (MDOF ) 系统，他们能等价于有高模式的影响的系统忽视了的 single-degree-of-freedom (SDOF ) 。结果证明时期比率，高度比率和山峰地面加速是在邻近的结构的最大的相对排水量上有大效果的主要因素。MDOF 系统的最大的相对排水量能从计算相等的 SDOF 系统的最大的相对排水量被获得。
英文摘要：
In order to give the reasonable width of seismic gaps to prevent the structural pounding during ground motions, the maximum relative displacement of adjacent structures is studied in this paper. The factors that may have effects on the maximum relative displacement are discussed. As for multi-degree-of-freedom （MDOF） systems, they can be equivalent to single-degree-of-freedom （SDOF） systems with the influences of high modes neglected. The results show that the period ratio, height ratio and peak ground acceleration are the main factors that have great effects on the maximum relative displacement of adjacent structures. The maximum relative displacement of MDOF systems can be obtained from calculating the maximum relative displacement of the equivalent SDOF systems.
