4.4.3.2 Limitation of interstorey drift
楼层间漂移极限
(1) Unless otherwise specified in Sections 5 to 9,the following limits shall be observed:
除第5至9节另有规定者外,应遵守下列限制：
a) for buildings having non-structural elements of brittle materials attached to the structure:
对于有脆性材料的非结构性单元依附于结构物的建筑物：
drν ≤ 0,005h ; (4.31)
b) for buildings having ductile non-structural elements:
对于有延性的非结构性单元的建筑物：
drν ≤ 0,0075h ; (4.32)
c) for buildings having non-structural elements fixed in a way so as not to interfere with structural deformations,or without non-structural elements:
对于有以不影响结构变形为目的安装的非结构性单元,或没有非结构性单元的建筑物：
drν ≤ 0,010 h (4.33)
where：
其中：
dr is the design interstorey drift as defined in 4.4.2.2(2);
dr是4.4.2.2(2)中规定的设计楼层间漂移；
h is the storey height;
h是楼层高度；
ν is the reduction factor which takes into account the lower return period of the seismic action associated with the damage limitation requirement.
v是考虑到与损失极限要求相关的地震活动间隔期较低的换算系数(折减系数).
(2) The value of the reduction factor ν may also depend on the importance class of the building.Implicit in its use is the assumption that the elastic response spectrum of the seismic action under which the “damage limitation requirement” should be met (see 3.2.2.1(1)P).has the same shape as the elastic response spectrum of the design seismic action corresponding to the “ultimate limit state requirement” in accordance with 2.1(1)P and 3.2.1(3)
换算系数v的值也可能取决于该建筑物的重要等级.其作用中隐含着的是,对地震活动时弹性反应谱应满足的“损失极限要求”的假定(见…).3.2.2.1(1)P)与设计地震活动弹性反应谱的形状相同,该设计地震活动是与“最大极限状态要求”相一致的,而该“最大极限状态要求”是依据2.1(1)P 和 3.2.1(3)的.
