ISO 24084:2022

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.
