“…These software take into account several factors such as thermal insulation, climate response, solar penetration, natural ventilation, mechanical ventilation HVAC systems, building dynamics and thermal mass" [28]. A complex assessment methodology and procedure for historic roof structures is proposed in [29]. Masonry structures are also most commonly analysed based on finite element methods.…”

Medieval Bourgeois Tenement Houses as an Archetype for Contemporary Architectural and Construction Solutions: The Example of Historic Downtown Gdańsk

et al. 2021

The basic urban tissue of medieval European cities consisted of brick townhouses. In the cities of northern Europe, these tenements were characterised by a block based on an elongated rectangular plan, covered with a gable roof with a ridge oriented perpendicularly to the street. The side walls of the tenement house were common for both neighbours and constituted a basic structural element. The gable façades were not loaded with ceilings, providing freedom in shaping them. The aim of this work is to determine the reasons why this method of shaping tenement houses in historical city centres has survived to the present day, becoming an archetype for contemporary architectural and construction solutions, despite the passage of time, numerous historical events, war damage, changing architectural styles, fashions and building techniques and technologies. The historical centre of Gdańsk has become the research material in this paper, where by means of such methods as historical source material analysis (iconographic), observation (operationalisation of preserved historical objects), comparative analysis of completed contemporary investments, and 3D modelling of structural systems, an attempt has been made to determine the main factors determining contemporary architectural and structural solutions. The reason for the extraordinary durability of this type of construction model can be found in the enormous rationality and efficiency of this solution. It allows for very intensive use of land, easy access of all front elevations to the main communication routes, cheapness of construction resulting from small spans and use of common structural walls for the neighbouring buildings, ease of shaping gable elevations, and fire safety. Aesthetic considerations are probably also important here, although it should be assumed that their significance began to grow only in the second half of the 19th century. However, it seems that the most important factor which made the model of the mediaeval bourgeois tenement house become an archetype for contemporary architectural and construction solutions is the timeless message contained in this model, a specific code allowing it to be unambiguously identified as a form of urban house – a place of safe living and at the same time a visible sign of the rich history of European cities, an element creating their cultural and spatial identity, a component of the living, constantly transforming urban fabric.

“…Studies performed on different roof structures from Timisoara brought forward that in the 18th and 19th century, roof structures were highly connected from an urban, architectural and philosophical point of view to their surroundings and to the building they belong to [15][16][17][18]. Since the city significantly developed at the beginning of the 20th century and roofs had an important role in defining the aesthetics and monumentality of the new buildings, an multi and inter-disciplinary analysis was also performed on the Löffler Palace, an imposing 20 th century palace which could highlight the importance of also consider urban planning principles, architectural and philosophical principles during the assessment of historic timber roof structures.…”

Historic roof structures are complex systems which cannot be assessed individually but need a more holistic approach, in order to understand them as a whole. The great variety of contexts in which the building and its roof were placed, of architectural styles which ultimately influence the shape of the roof but also the diversity of technical solutions used by the craftsman to respond to these needs and its state of conservation, make a multidisciplinary approach necessary. While 18th and 19th century roof structures from Timisoara, a city from the western part of Romania, proved out to be complex structures which a high value from urban planning, architectural, symbolical and structural point of view, the 20th century is a period of transition with a wide array of influences, mix of styles and technological improvement of the structures.Therefore, based on the roof structure of the Löffler Palace, built between 1912Palace, built between -1913 in the historic centre of the city, the paper tries to highlight that roof structures from this period are also far more than structural systems. Based on a thorough historical analysis and visual inspection of the structure, by using a multidisciplinary assessment procedure [1], the paper shows that 20th century roof structures are closely related to the building they belong, to their context and have a significant philosophical/symbolic and aesthetical value.At the same time, the procedure also addresses the role of assessment, diagnosis, conservation and maintenance, the structural integrity of the roof, its influence on the seismic behaviour of the historic building, highlighting the connection between the roof, the building and its environment.
