Untersuchungen zur Genauigkeit von magnetisch induktiven Betondeckungsmessungen

Assessment of the accuracy of concrete cover measurements using Eddy Current devices The use of non‐destructive testing in civil‐engineering (NDT‐CE) is well established to assess as‐built drawings for existing structures as well as for quality assurance of new buildings or in case of concrete repair. To gain reliable results the choice of the appropriate testing method in combination with the correct data assessment is essential. Hence this article starts with the basics of the two typical testing methods for concrete cover measurement with high precision. Methods based on Eddy Current and based on Radar are different. The strengths and limitations of both methods are presented. In the second part the achievable accuracy of concrete cover measurements using Eddy Current will be assessed for the most important parameters that have been varied in a wide range. It is shown how results are influenced by an improper input of the diameter or by the effect of neighbored rebars. At the end of the article it is shown how the deviation of the results can be minimized using the internal neighboring rebar correction of some of the devices. This article does not intend to be a product test rather the influence parameters of measurements close to reality will be identified and quantified how the accuracy of concrete cover measurements is affected.     

Beitrag zur Ermüdungsfestigkeit von Schienenschweißnähten bei Kranbahnen

Contribution to characteristic fatigue strength of rail welds at crane runways. The rail welds of today's crane runways usually made of hot rolled sections for light and moderate crane service form one important critical detail of the wheel load application in terms of fatigue. The characteristic fatigue strengths and the definition of damage accumulation under combined loading of the national and European design codes are compared and critically discussed. Moreover, an overview of the few, available test data of large‐scale specimens on the fatigue behaviour under wheel load application is given, and own girder tests are presented.     

Zustandsuntersuchung und Instandsetzung am Hauptdach des Hauses der Kulturen der Welt in Berlin

The main roof of the ”Haus der Kulturen der Welt“ in Berlin Which is very well‐known on account of its history and striking structural design – was to be inspected by the author to determine its condition and analysed with regard to the durability of the existing liquid synthetic sealant. The roof structure consists of a biaxial, curved area‐covering structural element with circumferential edge beams of pre‐stressed lightweight concrete. This is the result of the reconstruction between 1984 and 1987 following a partial collapse of the then Berlin Congress Hall in 1980. The very thin roof shell is also made of lightweight concrete and, like the edge beams, has a polyurethane‐based spray‐on seal that was specially developed for this purpose as protection against the ingress of moisture. The reason why this, at the time, novel type of seal was chosen was that it should take into account the fact that the roof design urgently needed some kind of protection against moisture that had to compensate the expected changes shape and crack movements of the roof with no damage. The following article reports on the nature, scope and main results of the analysis of the condition of the roof seal, edge beams and abutments. It will also describe the repair recommendations resulting from the investigations, which form the basis of the execution of work at the present point in time. Apart from presenting the technical principles and special features of the building that have to be taken into account during any repairs, the special features of the execution will also be addressed.     

Magnetoelastische Spannkraftmessung in Bauwerken

Magnetoelastic Measurement of Prestressing Force in Civil Structures The knowledge of the tensile force of prestressing steel elements and its reliable and non‐destructive determination are of essential importance for the assessment of the structural health condition of prestressed concrete structures and tie‐back systems in terms of structural safety, serviceability and durability. For the evaluation of the prestressing force in steel tension members, the measurement technique presented in this contribution is using the magneto‐elastic effect (ME‐effect) of ferromagnetic materials. This effect describes the reverse‐proportional correlation between the mechanical stress and the magnetic properties of ferromagnetic materials. The cylindrical coiled sensors pushed over the tendon and the measuring device developed and practically optimized at the iBMB/MPA of the TU Braunschweig enable a fast and reliable measurement of the prestressing steel force after an initial calibration. In this contribution first the state of the art of prestress measurement techniques for steel tension members is presented. Afterwards, the ME‐measuring method with the basics and merits of magneto‐elastic prestressing force identification is shown. Further recent research results as well as several building applications will be discussed.     

记忆的痕迹

历史是由“记忆”(memories)集合而成的。一般作为“建筑”的东西,往往都是由这些记忆以这种或那种形式组合而成。但是,“记忆”并不是对传统形式的参照;而“记忆的面孔”告诉我们,过去所有的重大发明都意味着对先前创造的超越。同样,当代的发明也推进了在此之前的历史。如何以当代的手段重新阐明或重新表现这些往日的碎片,就构成了令人感兴趣的并富有刺激性的建筑学沟通的新隐喻。类似这样的转换方法是推动建筑文化进步的手段。     

Seeing the eyes of god in human form: iconography and impersonation in african and hindu traditions of trance performance in the southern caribbean

ABSTRACT

This article links analysis of the body and of visual culture within religious studies through comparative examination of two southern Caribbean ritual traditions: Shango, or Orisha Worship (African), and Shakti Puja, or Kali Worship (Hindu). Both are centered upon subaltern ceremonies of trance performance and spirit mediumship. The article examines a primary difference in the impersonation of divinity evident between the two traditions—performing with one's eyes open on the African side versus closed on the Hindu side—and accounts for this contrast in terms of inverse relations between religious iconography and use of the body as a vehicle of ritualized form, referred to here as inverse conventions of “iconopraxis.” However, this level of differentiation is built upon a deeper, but no less cultural use of the body as a tool of entranced ritual praxis shared by each tradition. Each tradition therefore exploits similar phenomenological affordances of the human body in order to cultivate alter-cultural experiences of ceremonial ecstasy that, in turn, are modulated by differing conventions of iconopraxis. The analysis highlights the polymorphous nature of embodiment in accounting for similarities and differences of cultural symbolism in the ritual arts of trance.     

Erfahrungen bei der Beurteilung der Dauerhaftigkeit vorgespannter Bewehrung von älteren Spannbetonbrücken

Experiences due to the evaluation of the durability of prestressed reinforcements in old prestressed concrete bridges. Old prestressed concrete bridge superstructures exhibiting cracks across the prestressed reinforcement need detailed inspections for estimating maintenance requirements. Only this type of evaluation makes it possible to determine the required extent and nature of maintenance. In this paper essential steps of the “Directive of the durability of prestressed reinforcements in old prestressed concrete bridge superstructures” of the Federal Highway Research Institute are explained, also against the effects of growing heavy traffic with expected higher gross weights and axle loads.     

Colour and turbidity removal with reusable magnetite particles—VII: A colloid chemistry study of the effect of inorganic ions on the efficiency of clarification

The removal of colour and turbidity from natural waters by the addition of magnetite is an interfacial process. Furthermore the components of this system are either of colloidal dimensions or of a surface active nature and thus this method of water clarification is very much in the realm of surface and colloid chemistry. Electrokinetic techniques have been used to examine the influence of a number of inorganic species, commonly encountered in the practical situation, on the surface properties of magnetite and consequently on the efficiency of the process.     

Landscape Dynamics and the Management of Change

Change in economy and society is directly reflected in the character of landscapes, both in terms of their form and function and the landscape planning and management challenges which they present. The phenomenon of landscape dynamics within post-industrial society is considered and the development of a connection between the drivers of landscape change and the management response is sought. Two key drivers of landscape change are proposed - 'obsolescence' and 'dysfunction' - and these in turn are related to a management matrix bounded by axes of condition and character of landscape. It is suggested that the definition of these relationships helps to substantiate and more clearly define the tasks of landscape planning, design and management in the United Kingdom.     

Entwicklung eines baupraktischen Näherungsverfahrens zur Beurteilung der Zuverlässigkeit von Massivbrücken auf der Grundlage der Ergebnisse von Bauwerksüberprüfungen

Im vorliegenden Teil 2 des Beitrags wird die Entwicklung des baupraktischen Näherungsverfahrens für die Beurteilung der Zuverlässigkeit von Massivbrücken im Rahmen der RI‐EBW‐PRÜF vorgestellt. Wesentlicher Inhalt ist dabei die Modellierung der Modellunsicherheit Bauwerksprüfer, da die Bewertung der Mängel und Schäden an einem Brückenbauwerk durch den jeweiligen Bauwerksprüfer einen entscheidenden Einfluss auf die Zustandsbewertung hat. Zudem wird auf die Dimensionsanalyse von Grenzzustandsfunktionen näher eingegangen, da damit bei geschickter Normierung eine allgemein gültige Anwendung des Verfahrens erreicht werden kann. Die Anwendung des Verfahrens erfolgt mit einem Software‐Tool, das abschließend vorgestellt wird. In Teil 1 des Beitrags wurden die Grundlagen des Verfahrens sowie die Entwicklung der veränderten stochastischen Material‐ und Geometrieparameter infolge Schädigung behandelt. Development of an Approximation Procedure for a Structural Reliability Assessment of Reinforced Concrete Bridges on the Basis of the Results from Bridge Inspection Part 2 of the paper shows the development of the approximation procedure for the reliability assessment of reinforced concrete bridges according to RI‐EBW‐PRÜF. An essential part of this is the development carried out by the model uncertainty bridge inspector, as the respective bridge inspector's individual assessment of the damage of a bridge has a decisive influence on the condition evaluation. Furthermore, the dimensional analyses of ultimate limit states are shown, as the general use of the developed methodology can be achieved with an ingenious standardization. The application of the procedure with the developed software tool is presented in conclusion. Part 1 of the two papers describes the basics of the methodology and shows the development of the stochastic models for the material and geometry parameters which have changed as a result of damage.
