scope:

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.
