    Protecting a five span prestressed bridge against ground deformations2015In: IABSE Conference Geneva 2015: Structural Engineering: Providing Solutions to Global Challenges, Geneva: International Association for Bridge and Structural Engineering, 2015, p. 255-262Conference paper (Other academic)
    Abstract [en]

    A 55 year-old, 121.5 m long, five span prestressed bridge was situated in the deformation zone close to a mine in Kiruna in northern Sweden. There was a risk for uneven ground deformations so the bridge was analyzed and monitored. Results and measures taken to ascertain the robustness of the bridge are presented.The analysis resulted in an estimate that the bridge could sustain 24 mm in uneven horizontal and 83 mm in uneven vertical displacement of the two supports of a span. To be able to sustain larger deformations, the columns of the bridge were provided with joints, where shims could be inserted to counteract the settlements. To accomplish this, each one of the 18 columns of the bridge was unloaded by help of provisional steel supports. The column was then cut and a new foot was mounted to it. This made it possible to lift each individual column with two jacks, when needed, and to adjust its height by inserting or taking away shim plates.The deformations of the bridge and the surrounding ground were monitored. The eigenmodes of the bridge were studied with accelerometers and by analysis with finite elements (FE) models. Comparison indicated good agreement between the model and the actual bridge, with calculated eigenfrequencies of 2.17, 4.15 and 4.67 Hz, for the first transversal, vertical and torsional modes, respectively. Measurements during winter resulted in higher values due to increased stiffness caused by frozen materials.

    Avoiding undesirable end results of bonded steel fibre concrete overlays: observations from tests and theoretical calculations2014In: Nordic Concrete Research, ISSN 0800-6377, Vol. 49, p. 93-112Article in journal (Refereed)
    Abstract [en]

    Due to a high degree of damages and undesirable final results of bonded overlays, research has been conducted to develop recommendations on design and execution. Laboratory and half scale tests as well as theoretical analyses have been carried out including e. g. base and end restraint tests on overlays with various reinforcement, concrete qualities, substrate preparing and curing. Also, analytical and numerical calculations have been performed. Results reveal that the bond between overlay and substrate is the most critical parameter for a successful final result. Other key parameters are shrinkage and curing, while fibre and bar reinforcement generally proved to be less significant. Theoretical models work well on this case and will be further developed

    Prediction of stress development and cracking in steel fiber-reinforced self-compacting concrete overlays due to restrained shrinkage2010In: Fiber-Reinforced Self-Consolidating Concrete: Research and Applications, American Concrete Institute, 2010, p. 31-49Conference paper (Refereed)
    Abstract [en]

    Shrinkage cracking of self-compacting concrete (SCC) overlays with and without steel fibres has been assessed through laboratory testing and theoretical analysis. Test results verified that steel fibre reinforcement has a crack width limiting effect. However, the contribution in case of fibre contents up to 0.75 vol% was not found to be sufficient to distribute cracks in situations where bond to the substrate was nonexistent. Thus, even higher steel fibre contents (or other types of fibres) are required in order to control cracks. A distributed pattern of fine cracks was however obtained even for unreinforced SCC within bonded areas of the overlays. This implies that steel fibres, or other crack reinforcement, are not required if high bond strength is obtained. An analytical model, proposed to assess the risk of cracking and to predict crack widths in overlays, was found to give reasonable correlation with experimental results

    Abstract [en]

    Due to a high degree of damages and undesirable end results of bonded overlays, research is conducted to develop recommendations on design and execution. Laboratory and full scale tests as well as theoretical analyses have been carried out including e. g. base and end restraint tests on overlays with various reinforcement, concrete qualities, substrate preparing and curing. Moreover, analytical and numerical calculations have been performed. Results reveal that the e. g. bond between overlay and substrate is a critical parameter for a successful end result. Another key parameter is sufficient curing, while reinforcement generally proved to be less significant. Theoretical models works well on this structural situation and will be further developed.

    Fatigue strength of cable couplers in prestressed concrete beams1982In: Nordic Concrete Research, ISSN 0800-6377, Vol. 1, p. 5.1-5.14Article in journal (Refereed)
    Abstract [en]

    Fatigue tests have been carried out on ten prestressed concrete beams. Six of the beams were furnished with a cable coupler in the mid-span and four beams had no cable coupler. The uncoupled beams could in some cases sustain 9 times as many load cycles as the coupled beams. Some probable causes to the coupled beams lower fatigue strength are discussed in the paper.

    Thermal stresses in concrete structures at early ages1989Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis deals with the problem of formulating constitutive models for the analysis of early-age thermal stresses in concrete due to hydration. The main features of the work are constitutive modelling of early-age concrete behaviour experimental studies to check the models and to determine material parameters application of the models to some design and construction situations. The proposed model for thermal stress analysis in young con- crete is based on a rate-type viscoelastic law which is supplemented with a strain-softening model for high stress level nonlinearity in tension and by an adjustment for low- stress nonlinearity in compression. In order to demonstrate the potential of the model it has been applied to some typical cases in practical engineering. Thus, the risks of thermal cracking are computed for A - a section poured between inflexible supports B - a differential temperature field across a wall section C - a wall cast on a concrete slab D - a box tunnel element E - a concrete cover layer applied on a bridge pier. From the computations it is concluded that the magnitude of thermal stresses do not only depend on temperature variations but to a critical extent also on the mechanical behaviour of the hardening concrete as well as on the nature and degree of the restraint. The thermal stresses are in most cases not proportional to the temperature field within the structures as defined by maximum temperature rise, maximum temperature differences etc. It is evident from this study that, in some early-age applications, an analysis solely based on the temperature field may not even reveal whether a part of the concrete structure is in tension or compression.

    Abstract [en]

    At the Luleå University of Technology, research has been performed on thermal stresses and thermal cracking in maturing concrete in the last decade. Laboratory tests have been carried out providing material data for calibration of a proposed theoretical model for thermal stress analysis in young concrete. The laboratory tests included creep tests, free thermal volume change tests and relaxation tests. In the theoretical model, the thermal properties and the transient mechanical properties of the young maturing concrete as well as the restraint within the concrete element are considered. The model has been implemented in a computer program permitting the analysis of different concreting scenarios of which some examples are shown. In the examples, influences of different measures against cracking as well as influences of changes in temperature conditions, restraint, and mechanical behavior of concrete are quantified. For some cases in the computational studies it may be concluded that, for control of early-age thermal stresses and cracking in a structure, it is highly inadequate to consider only the early-age distribution of the temperature field within the studied structures.

    Temperatursprickor i betong p g a hydratationen för några vanliga typfall1994Report (Other academic)
    Abstract [sv]

    I samråd mellan Vägverket, Div. Väg och Trafik, Sekt. Broteknik (VTb) och Luleå Tekniska Högskola, Avd. för Konstruktionsteknik har ett antal förekommande typfall vid gjutning av betong studerats med avseende på temperaturspänningar på grund av hydratationen. För de studerade typfallen har spänningsanalyser utförtss och diagram framtagits över sprickrisk vid olika förutsättningar t ex gjutförhållanden och dimensioner. Diagrammen ger underlag för mer säkra sprickriskbedömningar än diagraam enbart baserade på temperaturberäkningar. Rapporten är indelad i tre delar. Del A berör hur temperatursprickor kan uppkomma, vilka huvudfaktorer som inverkar på sprickrisken, vilka förhållanden som gäller för aktuella typfall samt hur sprickrisker kan beräknas. I Del B sker en redogörelse för vilka förutsättningar som gäller allmänt vid sprickriskberäkningar och speciellt vid beräkningarna för typfallen. I Del B kommenteras de diagram över sprickrisker som redovisas i Del C. Del B och Del C kan användas separat vid sprickriskbedömningar.
