Structure and form

It will be apparent already that there is no unique relationship between structure and form if, by form, we mean simply the geometrical configuration of the structure. Different structural actions in response to the same loading, different strengths, and different stiffnesses may

all be associated with a single visible external geometry. They will vary according to the materials used, the internal detailing if the crosssections are not homogeneous, the manner and sequence of construction, and the scale. Moreover, in looking for the real structural form, it may first be necessary to peel off or look behind the skin that is normally seen if this is merely loosely wrapped over it to create a different visual impression, to hide services, or to provide insulation or other environmental control.
