Effect of inter-storey drift on cladding

In multi-storey construction, the effect often measured between storeys is called inter-storey drift . If the drift is too great and the components of the building envelope are rigidly fixed to the frame, damage can occur. Brittle elements such as windows can shatter, service pipes may rupture at joints and claddings may sustain damage.

The degree of drift that elements of the building envelope can withstand is largely determined by the design of their connections to the frame.

Inter-storey drift.

To avoid damage, the connections between the building envelope and the frame must be able to accommodate inter-storey drift.
