The destructive influence of external factors on building partitions in historic buildings

Irena Ickiewicz, Piotr Koda

The article presents the destructive influence of external factors on building partitions in selected historic buildings made from made full-bodied solid ceramic bricks. The external factors are an additional element that adversely affects the maintaining of historic buildings in a good technical condition, and they are complementary to a number of harmful factors that destructively act upon on such buildings. In order to estimate the range of damage in historic buildings, selected buildings that have been exposed to external factors for a long time in the Podlaskie and Warmińsko-Mazurskie Voivodships were analysed.

A short history of the form of octagonal and elliptical city

Maciej Motak, Magdalena Woźniczka

The article starts with the short discussion of two geometrical figures, i.e., octagon and ellipse, their genesis in architecture and urban design, and the examples of buildings whose plans were based upon them. Then, the selected octagonal and elliptical city squares are discussed: their genesis, context, layout, architecture surrounding the square, objects appearing in the square and, most specially, urban form and composition. The theory of architectural-landscape interiors has been applied to pinpoint the type of city squares by the assessing of the degree of openings in the square’s perimeter. The review consists of 22 case studies (9 octagonal and 13 elliptical) from the 15th to the 20th century. The last discussed case in each group, both atypical created in Krakow in the 20th century, are discussed even more thoroughly. The conclusions were presented first separately for octagonal and elliptical city squares and finally also for both groups in a comparative way.

Operational problems of tramway infrastructure in sharp curves

Włodzimierz Czyczuła, Maciej Rochel

Elements of the tramway track that require special attention in the design and maintenance of the tramway infrastructure are sharp curves (curves with small radii). In such places, there are a number of unfavourable operational problems, which are discussed in the article below. It describes the characteristics of such geometric elements and analyses the interaction of the wheel-rail system. Moreover, the most important operational problems are presented, such as the wear of wheels and tramway rails, the buckling of the rails, and noise and vibrations occurring during the passage of the tram. Methods of reducing unfavourable phenomena occurring on curves in the tramway infrastructure were also highlighted.

The new function of architectural monuments – a comparative analysis of two different cases: Palazzo Querini Stampalia and the Fondaco dei Tedeschi building

Dominika Strzałka

This paper discusses the long-term vision of the historic city development, where buildings assume a new function over time. The discussion is based on the example of Palazzo Querini Stampalia and Fondaco dei Tedeschi – two monuments restored to Venice in a new, different role. In the comparative analysis of the transformation of the buildings, particular attention was paid to the cultural, social and economic context of the city. This article aims to review the strengths and weaknesses of the new-use scenarios, outlining the renovation of the monuments and its added value for cities. The author concluded that no matter what the new function of the building is, it is worth renovating them, because this way the heritage can survive and this should be the central objective of a long-term vision.
