Dr. Anna Lobovikov-Katz - Technion Israel Institute of Technology Abstract Educational Linkage Approach In Cultural Heritage Buildings and other objects of the built heritage possess different values (see Module 1) and combine art, technology and material. Often structural elements whose primary role is to provide the building’s stability, are artistically shaped. In such cases structural elements have a dual function: technological/structural and artistic/ architectural. The current presentation is an overview of this subject. It explains and illustrates through examples, this “dual” aesthetical- technological role of structural elements, and the vice versa structural role of some architectural elements. It is targeted at developing a basic understanding of the integrity and mutual influence of art, material and structure in the built heritage.

Educational Linkage Approach In Cultural Heritage General introduction Cultural Heritage: What is it? Dr. A. Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide 5 According to the ancient Roman architect Vitruvius, architecture should be characterized by stability, use, and beauty. The building’s stability is guaranteed by proper planning of its structure, proper choice and use of materials and technologies. At the same time, certain proportions of structural elements could be perceived by the human eye as beautiful. Structural elements and details can be shaped on purpose as works of arts, e.g. sculptures.

Educational Linkage Approach In Cultural Heritage General introduction Cultural Heritage: What is it? Dr. A. Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide 6 People feel comfortable with certain proportion ratios and certain colors. This “comfortable” feeling changes from culture to culture, due to traditions and different ideas about what is considered beautiful. If the structure of the building has “good proportions” it can be a masterpiece in itself, without relation to any “added” artistic, e.g. sculptural elements. If you enter such building, famous for its harmony of proportions – you just feel it – no lecture or special course needed For centuries architects searched for ideal proportions, trying to develop universal formulas of beauty and ensure the beauty of buildings through certain calculations and geometry.

Educational Linkage Approach In Cultural Heritage Dr. A. Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide General introduction This is an example of the golden ratio which was used from ancient times. We are much more dependent on aesthetic traditions of the past than one might think. Even in modern life we “touch” golden proportion each time when we take a sheet of paper for the computer printer, - the paper is cut precisely according to the golden ratio, or, as it is called “divine proportion”.

Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide 8 Supporting elements Corbels and cantilevers (elements protruding from the buildings) supporting balconies, galleries and other protruding parts, were often shaped as sculptural elements, and may be richly ornamented. In this example in Ljubljiana, Slovenia, structural elements are covered with plaster moldings, in accordance with traditional local building techniques and the architectural design of the period when it was built Case studies

They might be protruding parts of the stones built into the stone wall. They might be of a simple design, like these corbels supporting a functional element in the fortifications of the city walls of Jerusalem.

Corbels and cantilevers (elements protruding from the buildings) supporting balconies, galleries and other protruding parts, were often shaped as sculptural elements, and may be richly ornamented.

In different epochs they were shaped differently and there are a great number of remarkable capitals through the history of built heritage Case studies

Columns

Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide 18 One of the most famous examples in the history of architecture, is probably the sculptures-columns – cariatides - of the Erechtheion, Acropolis, Athens. Column=sculpture There are abundant examples of shaping a structural element as a sculpture – or, vice versa giving a sculpture a structural role of an element supporting a certain part of a building, the sculpture=column, has been known since ancient times.

Two artistic- aesthetical factors here: decoration (painted surfaces of vaults) and the proportions of the vaults and ratio of their height and width to the other parts of this entrance space to the building. “Musikferein” - Society of the Friends of Music Building, Vienna, built in Vaults’ decoration

Vaults and arches

The deliberate use of different materials create the color contrast in this building. Vaults and arches

Due to these features, domes often play an important role in the architectural image of a city, and spaces covered by domes are focal points in the interior of these buildings. Domes

Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide 34 Arches, vaults, domes Arches, vaults and domes are often combined into one whole structure, like in this example, the Galleria Umberto in Naples (Napoli), Italy (initiated 1880-s) – one of the largest and most famous arcades in Italy. Its unique architectural aesthetics is steeped in the industrial use of metal and glass in building construction which spread widely at the end of the 19 th century.

Most of its sculptural décor does not bear structural function. However, its structural elements were provided a “sculptural finish” as well. Hotel De Ville, Grand Place, Brussels Case studies

Educational Linkage Approach In Cultural Heritage Case studies Dr. A. Lobovikov-Katz, Arch. – Topic 2.3: The integration of art, material and structure in built Heritage Slide 36 Structural integrity Structural integrity can be seen not only in the selected elements of the buildings. Structural systems influence the whole image of the building, e.g. early mediaeval vaults required solid thick walls which, in turn, resulted in small windows, while already in the Gothic period the development of the vaults allowed spatial vaults system bearing on columns rather than on walls, which was expressed in both interior and exterior (façades) of the buildings, etc. In this building in Venice, the architecture of the façade explains the load distribution of the whole structure – upper stories are “light” visually, while the lower part looks “heavy” because it has to bear all the weight of the upper stories.
