"The last of the requirements to be discussed, strength and rigidity, is a functional requirement that has important inter-relationships with other requirements. There is a further complication with walls because they may interact with the structural frame to contribute to its strength and rigidity. This inter-relationship may vary widely at the designer's choice, from curtain walls supported on the frame to designs in which walls contribute racking strength and rigidity or assist in carrying vertical loads. The extent of this inter-dependence must be considered in the structural design of both frame and wall.
There are, in addition, loads arising from wind that must be borne by the exterior wall and its parts; these must be transferred, together with the dead load of the wall, through suitable structural connections with the structural frame. This kind of structural analysis and design has been well established for many years and need not be discussed further. There is, however, one kind of loading arising out of dimensional changes in materials that deserves far more attention, particularly in the design of exterior walls and building frames, than it has yet received.
