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.
