本文件规定了评估幕墙在反复移动时对三向地震或风作用的层间位移抗力的试验方法。 测试方法允许根据施加的位移轴确定: —？水平层间位移面内阻力； —？水平层间平面外位移抗力； —？垂直层间平面内位移阻力； —？组合层间位移阻力。 试验方法可用于评估设计要求时的层间位移，或评估幕墙组件容纳的相对位移。 根据试样的尺寸和/或形状，可以手动或自动进行该测试。

This document specifies the test method to evaluate the inter-storey displacement resistance of curtain walling to three-directional seismic or wind actions when curtain walling is subjected to repeated movement. The test method allows to determine, depending on the axes of the displacement imposed: —    horizontal inter-storey displacement in-plane resistance; —    horizontal inter-storey out-plane displacement resistance; —    vertical inter-storey in-plane displacement resistance; —    combined inter-storey displacement resistance. The test method can be used to evaluate the inter-storey displacement either when it is a design requirement or to assess the relative displacement accommodated by the curtain walling assembly. This test can be addressed manually or automatically depending on the size and/or the shape of the specimen.
