The partial collapse of a prestressed concrete bridge without prior notice rightly made waves throughout society. The bridge in question is the Dresden Carola Bridge – an aesthetic and extremely slender structure that is justifiably regarded by experts as an engineering icon of its time, whose design and construction would still be a challenge under today's conditions. This first part of the article summarizes the history of the bridge's genesis, its design and construction, and presents the measures taken to maintain and renovate the structure. The second part, an attempt will be made to reconstruct the collapse process, and the search for the collapse causes will be described. In addition, the current monitoring will be discussed and an outlook on possible further action will be given.","PeriodicalId":55386,"journal":{"name":"Beton- und Stahlbetonbau","volume":"120 7","pages":"526-536"},"PeriodicalIF":1.0,"publicationDate":"2025-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635623","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A key concern in this context is differential settlements, which act as imposed deformations on structures, affecting both the internal forces within the foundation system—such as the internal forces of a shallow foundation slab—and the stress distribution in the superstructure. To consistently account for these effects, the chosen soil-structure interface must be capable of accurately representing the distribution of differential settlements or the curvature of the settlement profile. In geotechnical engineering, advanced nonlinear material models are commonly employed to realistically describe the complex settlement behavior of soils. In contrast, structural engineering often relies on linear elastic approaches. This paper investigates whether a linear elastic parameter set (E, υ) can be defined for a uniformly loaded foundation slab that, under specific boundary conditions, satisfactorily reproduces the settlement distribution of a geotechnical nonlinear calculation.","PeriodicalId":55386,"journal":{"name":"Beton- und Stahlbetonbau","volume":"120 7","pages":"484-493"},"PeriodicalIF":1.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After the first part of this publication series introduced the concept, development, and potential of this novel reinforcement technology, this paper summarizes the material characteristics determined through small-scale experimental investigations. The various process steps in the development of the reinforcement up to the final version are presented. In particular, the tensile load-bearing behavior of the reinforcement structure, investigated using fiber strand tensile tests, as well as the shape and compactness of the fiber strands formed the basis for selecting the preferred variant. Additionally, the test setup and obtained results are described in detail, demonstrating that the manufacturing method has a significant impact on the mechanical properties and quality of the reinforcement structure. In the upcoming parts of this publication series, further experimental investigations will be presented, focusing particularly on the bond behavior of the structure in concrete and large-scale component tests to analyze the shear load-bearing capacity.","PeriodicalId":55386,"journal":{"name":"Beton- und Stahlbetonbau","volume":"120 7","pages":"517-525"},"PeriodicalIF":1.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This requires geometrically and materially precisely manufactured modules, which can be implemented and largely automated in industrial prefabrication. However, such prefabrication is not yet common and is limited to similar serial components such as railroad sleepers. In the paper, a full-scale research facility is developed that keeps the individual steps of automated production in high-precision variable and opens them up to modules of any shape. The system can be used to develop the individual process steps of shuttering, reinforcing, concreting, hardening or qualifying, and to develop the overall process in a quality-assured rapid circular manner or to test meaningful alteration (adaptivity), such as in cross-sectional dimensions or shapes. Three robots are integrated for automation. They place free-form molds and built-in parts, weld reinforcements or qualify geometrically with lasers and stereo cameras or mechanically with rebound hammers. A special curing chamber with circulating air and heating plates with direct contact to the steel formwork enables controlled heat and moisture treatments for curing times of less than an hour. A simulation model is being developed as part of the plant's digital twin, which will help to improve the robot movements.","PeriodicalId":55386,"journal":{"name":"Beton- und Stahlbetonbau","volume":"120 7","pages":"504-516"},"PeriodicalIF":1.0,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144635123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
