STOREY STRUCTURES

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

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
