Les bâtiments à module porteur : réflexions sur un plan type du second âge du Fer

Abstract

Buildings with central supporting posts are often considered as a unique architectural type. On the contrary, the excavations of recent decades have shown the existence of a wide variety of plans. Five main types can be highlighted. They are based on several criteria: the presence or absence of the wall trench, its shape, particularly at the corners, but also the existence of peripheral supporting posts, or the distance of the wall from the central posts. These characteristics lead to two very different architectural designs in terms of statics: in one case, the vast majority of the weight of the structure is based on the single supporting structure of four or six posts; in the other, the weight is distributed between the internal posts and the wall, which can be supported on a sill beam or on peripheral supporting posts.
