Slidable connections from a support to a supported section combined with slidable end connections between adjoining supported sections allow relative motion between adjoining supported sections to be limited to less than the relative motion between adjoining supports. This is accomplished in an open-gap mullion embodiment for supporting a curtain wall assembly by providing an open gap between mullion sections equal to or less than a tolerable range for the curtain wall. When floor support deflections close the gap, further floor deflection causes an adjacent lower mullion section to provide support for the contacted upper mullion section. In a limited-gap embodiment, the gap between mullion section may exceed the tolerable motion of the associated curtain wall assembly, but a slidable gap-limiting means is provided to limit relative displacement between sections. In addition, the slidable mullion sections can be field installed without the need for field drilling and/or welding.
