REASSESSMENT OF LESSONS LEARNED FROM SHELLS FOR SPATIAL MULTI-
STOREY STRUCTURES
Maria BOSTENARU
Istituto Universitario di Studi Superiori di PaviaROSE School
Italy
Overview
Introduction
The engineering forms derived from the nave structure
The engineering forms derived from the metaphor of the nave
Conclusions
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
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
The Engineering Forms Derived from the Nave Structure: Lisbon
The Engineering Forms Derived from the Nave Structure: half-timber
Germany
England
The Engineering Forms Derived from the Metaphor of the Nave
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
The Engineering Forms Derived from the Metaphor of the Nave
Vienna
The Engineering Forms Derived from the Metaphor of the Nave
Frame and skeleton in the 20th century
The Engineering Forms Derived from the Metaphor of the Nave
Sacral and residential programmes
– exchange in architecural language
– exchange in structural language

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
