The structural engineer of the KÖFÉM I factory (1959) István Menyhárd (1902-1969) was a pioneer of shell architecture and theory already before WWII. His design clearly originates in his previous, pre-war works but the influence of international trends (eg. Brynmawr Factory /1946-1951/, structural engineer Ove Arup, Ronald Jenkins) is also noticeable – adding to its historical significance. The most remarkable feature of his design was a unique construction technology that made the shell roof extremely costeffective. Although its daring structural solution coupled with an ingenious construction technology eventually made the KÖFÉM factory an archetype of the most widely used shell-roofing typology in Hungary, it faced some major difficulties at the beginning: the 1:1 scale mock-up, ordered by the contractor collapsed. The investigation brought to light major constructional deficiencies, resulting in serious geometric imperfections that led to the collapse of the shell. The original structural concept was declared safe and the factory was eventually successfully constructed. Present paper investigates a parametric model of the mock-up structure with finite element analysis. The effect of various geometric imperfections (mentioned in the original documentation about the collapsed mock-up) is studied: non-uniform shell-thickness, non-accurate formwork, insufficient scaffolding. |
