Comparative interpretation of results after application of different non-destructive and portable techniques on historic concrete in the Centennial Hall in Wrocław
A multi-technique approach using non-destructive and portable techniques (NDPT) has proven effective for assessing the conservation state of historic concrete structures, as demonstrated by a study on Wrocław’s Centennial Hall. The research found that methods like ultrasonic pulse velocity, rebound tests, sponge test, Evanescent Field Dielectrometry (EFD), and colorimetric measurements yielded repeatable results when applied by different teams under similar protocols. These techniques allowed for the evaluation of concrete hardness, compactness, surface permeability, water and salt content, and color changes without invasive inspections. The study highlights the potential of this approach to inform conservation decisions for historic concrete buildings, offering a robust framework for monitoring their condition amid climate change and urban impacts.
New Form, New Material and Color Scheme, the Exposed Concrete Phenomenon—The Centennial Hall in Wrocław
Stratigraphic studies and archival research reveal that the Centennial Hall in Wrocław was originally intended to feature exposed concrete on its exterior while its interior would be adorned with painting, stained glass, and sculpture. Contrary to its current appearance, the external walls were initially covered with a translucent yellowish coating, presenting a distinct face of reinforced concrete architecture. This finding challenges the perceived aesthetic of the building and sheds new light on its design intent. The research was conducted as part of the CMP grant from The Getty Foundation's Keeping It Modern program, utilizing both stratigraphic tests and historical inquiries to uncover the building's original form and color scheme.
The image of contemporary architecture of Wrocław depicted in recent tourist commercial and Internet media
Contemporary public architecture, often overshadowed by historic landmarks, plays a significant role in enhancing the tourist attractiveness of Wrocław. This study reveals that modern architectural structures, including the Centennial Hall, are increasingly featured in tourist commercial and internet media, contributing to the city's progressive brand and shaping visitor perceptions. The research analyzed advertising materials, statistical data, and iconographic sources to identify frequently depicted contemporary buildings and assess their impact on tourism. Findings indicate that modern architecture can be a powerful element in promoting local heritage and boosting cultural tourism, challenging the traditional focus on historic sites.
Strengthening the 100‐year‐old reinforced concrete dome of the Centennial Hall in Wrocław
A century after its construction, the reinforced concrete dome of Centennial Hall in Wrocław—once the world's largest—was successfully strengthened using external prestressing techniques. This innovative approach addressed structural weaknesses in the 65-meter-diameter dome, ensuring its longevity while preserving its modernist architectural significance. The study involved a detailed assessment of the hall's condition, numerical simulations to model stress distribution, and the implementation of prestressing cables along the lower tension ring. Recognized as a UNESCO World Heritage Site for its pioneering engineering, Centennial Hall's renovation serves as a case study in sustainable heritage conservation, balancing structural integrity with historical preservation.
