  1. 1. IASS2005 5-11 September 2005 REASSESSMENT OF LESSONS LEARNED FROM SHELLS FOR SPATIAL MULTI- STOREY STRUCTURES Maria BOSTENARU Istituto Universitario di Studi Superiori di Pavia ROSE School Italy
  2. 2. Overview  Introduction  The engineering forms derived from the nave structure  The engineering forms derived from the metaphor of the nave  Conclusions
  3. 3. Introduction  Lessons re-evaluated in light of new understanding – Traditional constructions which behaved in earthquakes better than modern buildings – ‚local seismic culture‘ – The urban way of life leaded to these improvements – Ex. timber structures
  4. 4. The Engineering Forms Derived from the Nave Structure  dense inhabitation > multi-storey constructions  Coastal cities: building of naves – ‚industrial‘ work  Timber frame (Lisbon, Messina, Venice, Ionian islands, Istanbul, Germany, N France, England)  Ship structure – timber frame
  5. 5. The Engineering Forms Derived from the Nave Structure: Lisbon
  6. 6. The Engineering Forms Derived fro the Nave Structure: half-timber Germany England
  7. 7. The Engineering Forms Derived from the Metaphor of the Nave
  8. 8. The Engineering Forms Derived from the Metaphor of the Nave  Metaphor of the nave – Level of the facade – Level of interior space  France – Gothic  ‚nave structure‘  Frame-infill – bird-cage structure (like timber) – RC multi-storey structures  skeleton / infill – seismic codes – urban texture
  9. 9. The Engineering Forms Derived from the Metaphor of the Nave Vienna
  10. 10. The Engineering Forms Derived from the Metaphor of the Nave Frame and skeleton in the 20th century
  11. 11. The Engineering Forms Derived from the Metaphor of the Nave  Sacral and residential programmes – exchange in architecural language – exchange in structural language
  12. 12. The Engineering Forms Derived from the Metaphor of the Nave Arch. Ottokar Uhl Vienna
  13. 13. The Engineering Forms Derived from the Metaphor of the Nave Romania
  14. 14. The Engineering Forms Derived from the Metaphor of the Nave Cantilever Cassette-ceilings
  15. 15. Conclusions  Urban way of life – Industrial work – Dense inhabitation  Adoption of a certain engineering type for multi-storey construction  Ships withstand lateral forces like waves > good seismic behaviour of the buildings they inspired  Timber indigenous techniques – engineering skills  The design of spatial structures is like a laboratory where the possibilities of the new material are researched  Lessons to be learned for RC
