They worked with new typologies, such as multifamily high-rise buildings, and built them in the most important
cities of the country, during the fifties, reflecting the principles of the Modernity and with a strong formal conception
inspired in the International Style’s codes.
Concrete, as material and technology, allowed that those “Unity Centre” buildings become modern objects,
expressing the five-point formula that Le Corbusier enounced in 1927 and draw at the “Unité d’Habitation de
Marseille”, namely: the building lifted in pilotis, the free design of the plan, the free design of the façade, the
unbroken horizontal window and the roof terrace.
In Lisbon, late forties urban plans transformed and expanded the city, creating modulated buildings repeated in
great extensions – that was a progressist idea of standardization. The Infante Santo complex is a successful adaptation
to the Lisbon reality of the Modern Urbanism and Architecture.
In the fifties, it was built a large number of Modern housing buildings in Lisbon, with structural characteristics
that, in certain conditions, can induce weaknesses in structural behaviour, especially under earthquake loading. For
example, the concept of buildings lifted in pilotis can strongly facilitate the occurrence of soft-storey mechanisms,
which turns these structures very vulnerable to earthquake actions.
The development and calibration of refined numerical tools, as well as, assessment and design codes makes
feasible the structural safety assessment of existing buildings. To investigate the vulnerability of this type of
construction, one building representative of the Modern Architecture, at the Infante Santo Avenue, was studied. This
building was studied with the non-linear dynamic analysis program PORANL, which allows the safety evaluation
according to the recently proposed standards.|
