Abstract:
In April 2004, a scanning tour of Japan, the Netherlands, Belgium, Germany, and France was made to obtain information about bridge construction methods being used to minimize traffic disruption, improve work zone safety, minimize environmental impact, improve constructibility, increase quality, and lower life-cycle costs. From information obtained from the tour, 10 technologies were identified for further consideration and possible implementation into U.S. practices. These included two technologies that allow bridges to be built off site and then moved to their final location in a short time, three superstructure systems and four deck systems that facilitate faster and safer construction, and one substructure system. The two technologies for moving bridges were self-propelled modular transporters and other moving systems, including skidding or sliding, incremental launching, floating, rotating, and lifting of bridges into place. The superstructure systems included a precast concrete deck system known as the Poutre Dalle system, the use of partial-depth concrete decks prefabricated on steel or concrete beams, and U-shaped precast concrete segments with transverse ribs. The deck systems involved full-depth prefabricated concrete decks, special cast-in-place closure joint details, hybrid steel–concrete deck systems, and a multiple-level corrosion protection system. The substructure system consisted of stay-in-place precast concrete panels that serve as both formwork and structural elements for solid and hollow bridge piers.

Abstract:
We are going to present in this article an actual problem in the production of prestressed concrete prefabricated elements. There is a problem of high transport costs in the case of bridges, that are made from prefabricates. In the production of T type or double T type cross section we can have a situation that the form could be more than 100 m long and prestressing force is self-fixed. Putting the polystyrene in the form we can produce 10 or more beams in one step. From a viewpoint of theoretical background this steel form represents a problem of stability and friction. A special steel assembled frame for the production of prestressed prefabricates could be arranged close to the bridge site. Horizontal deformations represent a special problem. Friction effect is introduced as the simplification of elastic support. Non-linear solution has been used.

Abstract:
Unixial compression tests have been conducted to investigate the influence of bridge length between two collinear cracks on the specimen strength and fracture patterns. Based on the local connectivity rate of cracks, the evolution of the fracture patterns of the bridge is illustrated. It can be concluded that the sensitivity of the strength to the bridge length is reduced as the connectivity rate, L, is higher than 0.8. The fracture pattern composed of tensile and shear fracture will be induced in rock bridges when the bridges are short. Wing cracks develop well as the distance between prefabricated cracks increases, however, the fracture events caused by the conjunction of the secondary cracks are restrained.

Abstract:
This thesis deals with prefabricated composite bridges in general, and prefabricated concrete deck elements with dry joints in particular.As outlined in Paper I and Chapter 2 prefabrication has several advantages over in situ construction, and has hence been discussed for decades in the construction business. Further, the house building sector has taken large steps towards a more industrialized approach, in which prefabrication, lean thinking and Building Information Modelling (BIM) are all important components. Numerous studies have also examined the applicability of such an approach in the bridge sector, and several types of prefabrication techniques have been tested. Nevertheless, in many countries the bridge sector seems to lag far behind in the general shift towards more industrialized construction processes. One of the reasons for the relatively slow progress may be the fact that bridges are often unique objects with unique specifications and constraints. This hinders the standardisation that is often regarded as a key to industrialised construction.Chapter 2-3 and Paper I, presents evidence from a literature review together with information gathered from a Workshop, attended by bridge designers and researcher in Europe and the US, that prefabricated deck elements are still quite rarely used in bridge construction. Deck elements with dry transverse joints are even rarer. Few examples have been reported. In addition, the degree of prefabrication and the rate of progress towards more industrialised construction processes seem to vary substantially from one country to another.However, as described in Chapter 3 and Paper II, a prefabricated concrete deck element system with dry joints has been developed in Sweden for constructing composite bridges. The transverse joints are completely dry, and all forces are transferred by contact pressure between concrete surfaces. This implies that no tensional forces can be transferred over the transverse joints. Shear forces are transferred by overlapping concrete shear keys, designed as a series of male-female connections. The research presented in this thesis is focused on the structural behaviour of this deck element system. In order to investigate this, laboratory tests have been performed as well as field monitoring.Results of large-scale laboratory tests, presented in Chapter 4 and Paper V, show that a bridge of this type is less stiff than a similar bridge with an insitu cast deck slab. The concrete elements’ contributions to stiffness are negligible in sections with hogging moments, but make some contribution to global stiffness in sections with sagging moments. At moderate load levels, the interacting concrete area is much smaller than in a similar in-situ cast section. This is believed to be due to the combined effects of small gaps in the joints and continuous in-situ cast concrete in the injection channels.After the channels have been injected, existing gaps will be more or less permanent, since the in-situ cast concrete must be compressed up to a certain limit before the rest of the joint will be closed. Destructive testing showed that the differences in stiffness and stresses between a deck of this type and an in-situ cast bridge deck are much smaller in the ultimate limit state. In this case it could even be reasonable to design a cross-section according to Eurocodes, neglecting effects of the joints.As shown in Chapter 5 and Paper III, the overlapping shear keys are a critical detailing in this deck system. Therefore, they were tested in the laboratory to determine how they fail and evaluate their load capacity. The tests revealed two failure modes. The first is a rather ductile failure, activating the shear reinforcement. This was the expected failure mode for shear keys of this design. The second failure mode observed was a quite brittle failure in the concrete covering layer. It has only been observed in small-scale tests, and might be related to the test set-up. Nevertheless, overlapping of the rebars in the male-female shear key connection is strongly recommended to assure the robustness of shear transfer if failure occurs in the concrete covering layer.To complement the laboratory tests, a single span bridge was monitored in the field (Chapter 6 and Paper IV). The bridge was built in 2000, using the prefabricated deck system that this thesis is focusing on, and was tested in both 2001 and 2011. The tests, and subsequent Finite Element analyses, showed that under moderate loading the interacting concrete area is smaller than for a similar in-situ cast bridge. No significant long-term effects were observed, except that under eccentric loading the distribution of the deflection between the girders decreased slightly during the 10 years between tests. This indicates that the joint gaps may have narrowed and at least partly closed during this time.Chapter 7 summarises the research and presents recommendations for dealing with general issues related to the design and construction of a bridge of this type. The design methods are generally the same as for a conventional composite bridge with an in-situ cast deck slab. However, the Eurocodes require some modification for the design of prefabricated deck elements with dry joints, particularly regarding global analysis and the resistance of cross-sections. Finally, conclusions, a general discussion and suggestions for further research are presented in Chapter 8.
Denna avhandling behandlar ämnet prefabricerade samverkansbroar i allmänhet och prefabricerade betongelementfarbanor med torra fogar i synnerhetPrefabricering är ett ämne som har diskuterats i byggbranschen under de senaste decennierna. Husbyggnadsindustrin har gjort stora framsteg i riktning mot ett mer industriellt tänkande, i vilket prefabricering, Lean och BIM är viktiga pusselbitar. Även i brobranschen har mängder med forskningsprojekt utförts runt om i världen och flertalet olika prefabricering lösningar har testats genom åren. Trots detta så förefaller det så att brobranschen ligger lång efter i utvecklingen mot en mer industrialiserad byggprocess. Den långsamma utvecklingen kan till viss del förklaras av att varje bro ofta är ett unikt objekt med unika förutsättningar. Detta utgör ett hinder mot standardisering vilket ofta är beskrivet som nyckeln till industrialiserat byggande.En litteratur studie kompletterad med en Workshop, för insamling av information och erfarenheter från brokonstruktörer och forskare i Europa och USA, visar att prefabricerade farbaneelement fortfarande är ganska ovanliga på den globala byggmarknaden. Farbaneelement med torra fogar förefaller vara extremt ovanliga, enbart ett fåtal exempel har påträffats i litteraturstudien. Prefabriceringsnivån och utvecklingstakten mot ett mer industriellt byggande varierar mycket från ett land till ett annat. (Paper I och Kapitel 2-3)För samverkansbroar har ett prefabricerat farbanesystem med torra fogar mellan betongelementen utvecklats i Sverige. De tvärgående fogarna är helt torra och all kraft överförs genom kontakttryck mellan olika betongytor. Detta medför att inga dragkrafter alls kan överföras genom fogen. Tvärkrafterna överförs genom överlappande betongklackar som är utformade som en serie av hane-hona kopplingar. Forskningen som presenteras i denna avhandling är fokuserad på konstruktionens strukturella beteende. Detta beteende har undersökts via labbtester såväl som genom fältförsök. (Paper II och Kapitel 3)Storskaliga labbtester visar att en bro av denna typ är mindre styv än en liknande bro med en plastgjuten farbaneplatta. I områden med negativt böjmoment är betongelementens bidrag till styvheten försumbart. I områden med positivt böjmoment bidrar betongelementen till den globala styvheten. Vid måttlig belastning är dock den medverkande betongarean avsevärt mindre än i en motsvarande platsgjuten konstruktion. Detta orsakas förmodligen av de små glipor som finns i fogarna, i kombination med det faktum att de injekterade kanalerna är kontinuerliga över elementskarvarna. Detta medför att de initiala fogöppningarna mer eller mindre blir permanenta då kanalen injekteras, eftersom den injekterade betongen i kanalen måste tryckas samman till en viss gräns innan den resterande delen av fogen stängs. Förstörande provning visar dock att skillnaderna i spänningar och styvhet är avsevärt mindre i brottgränstillståndet. Det är därför rentav rimligt att utföra tvärsnittskontroller, i brottgränstillstånd, i enlighet med de regler som anges i Eurokoderna och därmed försumma de effekter som fogarna ger upphov till. (Paper V och Kapitel 4)De överlappande betongklackarna är en väsentlig detalj i det aktuella prefabriceringssystemet. Dessa klackar har därför testats i ett laboratorium för att för utreda hur de går i brott samt vilken last kapacitet som de har. Testerna resulterade i två olika typer av brott. Den första typen av brott aktiverade skjuvarmeringen, vilket resulterade i ett tämligen duktilt brott. Denna var även det förväntande brottscenariot och tämligen i linje med de dimensionerings metoder som föreslås för denna typ av betongklackar. Den andra typen av brott som observerades var ett tämligen sprött brott i betongens täckskikt. Denna typ av brott har enbart observerats i dessa labbtester och är möjligen relaterad till utformningen av testriggen. Det rekommenderas dock starkt att utforma armeringen i klackarna så att armeringsjärnen i hona-hane överföringen överlappar varandra. Detta för att säkerhetsställa en residualhållfasthet för skjuvöverföringen även efter ett eventuellt brott i betongens täckskikt i klackarna. (Paper III och Kapitel 5)Som ett komplement till labbtesterna har fältförsök utförs på en enspannsbro. Den aktuella bron byggdes år 2000 med den prefabriceringsteknik som denna avhandling behandlar och har instrumenterats såväl år 2001 som 2011. Även dessa tester och de efterföljande FE-analyserna visar att den medverkande betongarean, under måttlig belastning, är klart mindre än den medverkande arean för en platsgjuten betongfarbana. Inga väsentliga långtidseffekter har kunnat observeras. Enbart nedböjningsfördelningen mellan balkarna, vid excentrisk last, har minskat en del efter 10 år. Denna skillnad kan indikera att fog öppningarna var större år 2011, dessa kan åtminstone delvis ha stängts under den tid som förlöpt mellan testen. (Paper IV och Kapitel 6)Huvuddelen av denna avhandling avslutas med ett kapitel som summerar den utförda forskningen genom att presentera råd och förslag på hur det går att hantera generella konstruktions- och produktions-frågor för en bro av denna typ. Dimensioneringsmetoderna är i regel de samma som för en konventionell samverkansbro med platsgjuten farbana. För denna typ av prefabricerade farbaneelement finns det dock vissa områden där dimensioneringsreglerna i Eurokoderna bör modifieras eller rentav ändras. Systemanalys och tvärsnittskontroll är två av de dimensioneringssteg där reglerna i Eurokoderna bör modifieras en del. (Kapitel 7)

Abstract:
O Estado do Pará tem uma área de 1.253.164,49 \'KM POT.2\', possui uma malha hidrográfica abundante e aproximadamente 19.253,35 km de estradas vicinais, que são cortadas por muitos rios. Neste contexto, a construção de pontes com pequenos e médios vãos é imprescindível para a melhoria do transporte intermunicipal e interestadual. O sistema de treliças modulares para pontes, já estudado no Reino Unido, Brasil e implantado na África, como também na América Central, se adéqua bem ao estado, e é constituído por vigas treliçadas planas, que utilizam peças serradas de madeira com seções transversais comerciais na composição da superestrutura da ponte. Procurando-se implantar o sistema no Pará, esse trabalho tem por objetivo a adequação do projeto de uma ponte treliçada de Eucalipto citriodora em projetos com madeiras tropicais, como Maçaranduba, Jatobá e Ipê. Para esta finalidade o sistema modular treliçado foi estudado por meio de análise numérica e experimental, e avaliado para pontes de até 36 m, com superestrutura formada por vigas treliçadas de madeira com 1 m de altura e ligações parafusadas. Como resultado deste estudo foi elaborada uma tabela contendo o número de vigas treliçadas a serem utilizadas em uma largura de ponte de 3,80 m dependendo do tamanho do vão. O sistema proposto proporciona vantagens como redução de custos e maior rapidez de execução, além de posterior reaproveitamento dos módulos.
The Para state has an area of 1.253.164,49 \'KM POT.2\'; it has an abundant hydrography and nearly 19.253,35 Km of vicinal roads, that are cut by many rivers. In this context, the construction of bridges with small and medium spans is essential to the improvement of intercity and interstate transportation. The system of modular timber truss bridges, was already studied in the United Kingdom, Brazil and used in Africa, as well as in Central America, fits well to the state, and it is composed of beams plane trusses, using sawed pieces of wood with commercial cross sections in the composition of the superstructure of the bridge. With the purpose of installing the system in Para, the aim of this work is the adequacy of the design of a Eucalyptus citriodora\'s truss bridge on projects with tropical woods, as Maçaranduba, Jatoba and Ipe. For this purpose, the modular truss system was studied by numerical and experimental analysis, and evaluated for bridges with spans up to 36 m, with the superstructure using timber trusses beans with 1 m height and bolted connections. As result, was presented a table containing the number of beam trusses to be used in a bridge\'s wide depending on the size of the span. The proposed system provides advantages such as lower costs and faster execution, besides subsequent reuse of modules.

Abstract:
Prefabricated concrete elements are widely used in the construction industry today. With advantages such as time savings, increased safety at the construction site and minimized material usage, prefab becomes a major challenger to the traditional on-site casting construction method. However, constructing a bridge in concrete still presents challenges when using prefab as a construction method. Hence, more research in the area is needed. This master thesis has been studying the behavior of a prefabricated skew angle slab and the connection between the slab and wall elements of a bridge. The study was conducted using a finite element software, where three 3D-models of skew angle slabs were created. The three models had different skew angles (0, 15 and 30 degrees) and crossed the same path. The models could represent both the slab and the slab-wall connection. The finite element analysis showed that slabs with angles up to 15 degrees could be designed as a straight bridge. However, when the skew angle increases to 30 degrees, the behavior of the slab and connection changes significantly. Furthermore, the results show that a stress concentration occurs in the obtuse corner and that the stress increases when the skew angle increases. Moreover, there is a slight uplift in the acute corner when the skew angle increases to 30 degrees.

Full text
Abstract:
Prefabricated and pre-stressed reinforced concrete beams and girders are integral components of many highway structures, including those built by rapid construction techniques. Concerns exist regarding the development of cracks during curing, form removal, detensioning, transport, installation, and operation. Non-destructive, Acoustic Emission (AE) sensing techniques have the potential for detecting and locating cracking in prefabricated, pre-stressed concrete girders used as Prefabricated Bridge Elements and Systems (PBES) used in rapid construction practices as part of a Quality Assurance/Quality Control (QA/QC) program. AE sensing records transient elastic waves produced by the release of stored elastic energy resulting in plastic deformations (i.e., crack nucleation and growth) with an array of point sensors. The AE instrument system is relatively portable which can allow for it to be an option for both off-site fabrication QA/QC as well as on-site field QA/QC. This thesis presents a multi-stage research initiative on acoustic emission monitoring of prefabricated and pre-stressed reinforced concrete beams used in highway bridge construction during detensioning, craned removal from formwork and transport to bridge sites, along with supporting laboratory tests and numerical analysis. The specific objectives of this research were to: 1. Identify suitable instruments to monitor pre-stressed and/or post-tensioned concrete girders for cracking activity; 2. Design and develop a reusable instrumentation package; 3. Measure performance and condition of concrete girders during fabrication and transport; and 4. Identify test protocols and possible accept/fix/reject criteria for structural elements based on information from monitoring system. Presented are results from laboratory, full-scale girder fabrication, and transport monitoring, along with overall conclusions and recommendations for future research.

Abstract:
The inverted-T bridge system is a rapid bridge construction technique that consists of precast inverted-T girders placed adjacent to one another and covered with a cast-in-place deck. This system was first implemented in the U.S. by the Minnesota Department of Transportation (Mn/DOT). This research focuses on improving the constructability of the Mn/DOT system while maintaining the systemâ s structural performance characteristics. To accomplish this goal, five sub-assemblage specimens were cast and tested in the structures laboratory at Virginia Tech. These tests focused on identifying an improved precast girder geometry and transverse sub-assemblage connection for this system. From this study it was found that all of the proposed specimens behaved adequately at service load and strength. From these results, it is recommended to further evaluate a specimen with a tapered profile and no physical connection between precast girders for use in a Virginia Department of Transportation bridge near Richmond, VA.

Abstract:
Purpose: This study aimed to conduct a case study, with focus on work environment, economy and technical implementation, to determinate the difference if a prefabricated bridge had been constructed instead of a cast-in-situ bridge. Method: The study is based on a literature study and a case study. The case study is mainly based on interviews, data collection and attendance at the construction site. Results: The result of this study was that it is possible to combine both on-site and prefabricated elements, not as requested but as a beam frame bridge. The best option would be to cast the foundation on site and use prefabricate beams and retaining walls.  Prefabricated elements are constructed in a more controlled environment and therefore it is easier to fulfil a better work environment. If the actual bridge were to be made with prefabricated elements instead of layed on-site, the price would not differ too much. Conclusions: The big difference between prefabricated elements and on-site concrete is the labour and the material cost for the formwork. The biggest risk, regarding work environment from both perspectives, was identified as working at heights and vehicle in movement.

Abstract:
<p>Prefabricated modular steel orthotropic deck panels can provide effective solution for accelerated construction of bridges in constrained urban landscape. These welded steel decks are ideal manufacturable products incorporating repeated details that are amenable to automated fabrication. Based on the lessons learnt from service performance of these decks and the knowledgebase from significant research performed over the years, a standard deck design is proposed, which can be easily integrated as a prefabricated modular deck for rapid and economic construction of short and medium span steel girder and stringer bridges both for new construction and rehabilitation. This deck design effectively addresses the challenges to wide spread implementation of steel orthotropic decks for medium and short span bridges, providing a life-cycle cost-effective solution for urban bridge infrastructure.</p>

Abstract:
<p>Seismic resistant retainer is an important component for seismic design of the medium‐small span bridges. However, it’s difficult for the bridge engineers to design a reasonable transverse retainer due to deficiency of design detail in most of current seismic design specifications. Therefore, this paper proposed a prestressed prefabricated concrete retainer that utilize the ultra‐high performance concrete (UHPC). Firstly, the structural characteristics and the seismic design method of the new proposed retainer is illustrated. The OpenSEES model of the case‐study bridge were simulated by considering three different types of seismic resistant retainers. A total of ten high intensity ground motions were selected to conduct the nonlinear time history analysis (NTHA). Subsequently, to investigate the seismic performance of the proposed UHPC retainer, this paper performs the comparative study of seismic responses for different bridge components. It is concluded that, the proposed retainer can provide excellent displacement capacity and help to reduce the seismic damage of bridge piers significantly. In addition, the new retainer has strong ability to keep self‐centering to help the bridge reducing the residual displacement of superstructure under strong seismic events. The proposed UHPC retainer is applicable to the rapid prestressed prefabricated construction process and has a clear load transfer mode under earthquake actions. Therefore, it is a good candidate to the multi‐level performance‐based seismic design of the medium‐small span bridges.</p>

Abstract:
<p>For the use of popular GFRP composite materials for the construction of considerable-size facilities such as, for instance bridges, it is required to manufacture the finished prefabricated composite units joined together. The various manufactured composite panels are used in bridge decks on the bridges. The panels have system connections and allow them to be quickly assembled. One of the examples are the th-5 panels manufactured by a pultrusion method, used in bridges and helicopter pads. Considering the exceptionally light, fire-resistant and heating bridge deck the composite panel constitutes an attractive alternative for aluminium in helicopter pads and sidewalks for pedestrians and cyclists on bridges. Passenger drones that are expected to be used in the near future will require light-weight landing field structures located on the existing buildings.</p><p>The developed author’s innovative system for extending the existing bridges by adding sidewalks for pedestrians and cyclists (Fig.1) is called the “velo-pont” and is based on the use of composite panels. The individually designed click-clack connection is an innovative author’s solution for longitudinal joining of panels. Such solution can successively be used for bridges with a long sidewalk, even several hundred meters long.</p><p>The proprietary solution has been examined and tested. A prototype has been made to a real scale. The system solution has been already used in practice for several bridges in Poland.</p>

Abstract:
<p>Time dependent deterioration of bridge decks, directly subjected to: repeated abrasive loading from passing vehicles; the elements of weather; and winter maintenance agents, is the key challenge to achieving a 200 Year Bridge Design. In-service performance and laboratory tests over the past several decades have demonstrated that the steel orthotropic deck is the only system likely to accomplish this goal. Nevertheless, implementation of this deck system has been mostly limited to long span signature bridges, movable bridges, and temporary structures. The primary impediments to more wider application of orthotropic decks are lack of robust standards, increased efforts required for advanced analysis and design, relatively high initial cost owing to intensive fabrication, and most importantly due to concerns regarding higher possibility of in-service fatigue cracking from a large number of welded connections. This manuscript presents a standard deck design, developed based on the lessons learnt from a number of orthotropic bridge decks implemented in the greater New York region and the knowledgebase accumulated over the years from research and service performance of this deck around the world, which can be widely implemented as a prefabricated modular system towards durable, sustainable and life-cycle cost-effective design of the 200 Year Bridge.</p>

Abstract:
<p>The Boomerang and Jungle pedestrian bridges form part of a new pedestrian and cycle path, passing from the centre of Oslo through an urban forest and over the Outer Ring Road. The main goal for the design team was to integrate the bridges’ architecture within the natural environment and to cause the minimum impact during the construction period. The 85m long Boomerang bridge, named after its shape in plan, crosses the ring road with a 22.5m span, whose traffic was maintained throughout the construction period. In total the bridge comprises of four spans, with a continuous steel box girder of asymmetric cross-section. The bridge and the railings are fabricated from Cor-ten weathering steel to avoid the need for painting and to minimise future maintenance. The Jungle Pedestrian bridge is a simple suspension bridge spanning 36m over a small river. The main structural elements are parabolic, locked coil cables, four at deck level and two at handrail level. The deck is formed from slip-resistant perforated steel panels, supported off a transversely stiff steel framing system. The design intent was to maximize the use of prefabricated lightweight elements to facilitate the bridge erection and minimize the impact on the natural environment. Due to the lightness of the bridge a detailed analysis of the accelerations due to pedestrian-induced vibrations was performed to assess the comfort level for bridge users. The project won in 2017 the Norwegian Steel Construction Award and was nominated for World Architecture News’ Best Bridge Award 2017.</p>

Abstract:
<p>The integral expansion joint is a novel bridge expansion joint for bridges and viaducts with three breakthrough characteristics: (1) allows continuous driving, therefore (i) reducing the risk of accidents and increases safety for the road user and their vehicles; (ii) mitigating noise (the bump effect from conventional joints); (2) avoids the filtering of water, detritus and de-icing salts reducing conservation costs (opex and capex) of bridge substructures; (3) has a long-service life vis-à-vis conventional joints, therefore: (i) reducing the maintenance expenditure in bridge joints (life-cycle cost analysis); (ii) reducing traffic cuts and diversions, relevant for toll road operators where there is payment for - or penalties due to lack of – availability and (iii) reducing potential management liability due to improper maintenance. At an affordable supply and installation cost - aligned to conventional joints -, the integral expansion joint aims to solve a well-documented and historical problem in Structural Engineering, strengthening the most vulnerable part of any bridge and road surface. It can be prefabricated or manufactured in situ, implemented in all kind of bridges (new or rehabilitation), in any geography (thermal range), regardless of length of the deck or skewness, and in any material (concrete or metal).</p>

Abstract:
<p>Paudèze bridges are two 400‐m long parallel highway bridges located in Switzerland and opened to traffic in 1974. After over 40 years of service life, both bridges must be completely rehabilitated and strengthened while constantly maintaining 2 traffic lanes in both directions.</p><p>The bridge deck slab was strengthened using UHPFRC (Ultra‐High Performance Fiber Reinforced Concrete) struts. These inclined struts connect the end of the deck slab cantilever and the box girder web, forming a Warren truss. They thus reduce the bending moments in the deck slab and the existing steel reinforcement could be kept.</p><p>The joint between the prefabricated UHPFRC struts and the existing concrete web is done through a cast in‐ place UHPFRC beam, without any mechanical connection. Forces go through the joint and into the web by a combination of friction and compression forces.</p><p>Various experimental tests and numerical simulations confirmed the feasibility of this solution. In particular, the UHPFRC‐concrete web connection, the UHPFRC‐UHPFRC connection and the global behavior of the strut were tested and modelled.</p><p>The strengthening of the bridges decks took place between 2017 and 2019. The developed solution, using UHPFRC struts, was shown to be very effective to strengthen the deck and creates a rhythm in the structure.</p>
