A structural assembly, e.g. a curtain-walled building, comprises load-bearing floor slabs at successive levels and a framework of the curtain wall has vertical mullion members through which it is secured to the floor slabs at a spacing from the floor slabs. Fire-resistant panels are interposed in the gaps to check the passage of smoke and flames between floors. The panels overlie the rear faces of the mullions over a depth substantially greater than that of the floor slabs and bear against said rear faces to reinforce the mullions against wind loads. Any residual spacing between the panels and the floor slabs can be closed by fire-resistant elements that also form service ducts.

A structural assembly comprising a supporting structure and a curtain wall framework, said structure comprising at least one horizontally extending load-bearing member, said curtain wall framework comprising a plurality of upwardly extending, laterally spaced mullion members, tie-back elements fixed to said mullion members and to said at least one load-bearing member to secure the framework to the supporting structure inner faces of said mullion members being located by said tie-back elements in a position outwardly spaced from said at least one load-bearing member, whereby regions of said inner faces are located opposite and adjacent said at least one load-bearing member, a plurality of fire-resistant members interposed in the space between the framework and said at least one member and supported through said at least one member, said fire-resistant members overlying said inner faces of the mullion members and forming a substantially continuous barrier between said framework and said at least one member, said barrier at least partly filling the space between said framework and said at least one member.
