Hot‐dip galvanized composite dowel strips
Steel Construction, 2016AbstractThis paper presents additional potential for the future economic development of composite dowel strips by using the durable and long‐lasting corrosion protection of hot‐dip galvanization. Based on the completed FOSTA research project P835 [5] on the use of hot‐dip galvanizing for steel and composite bridge construction, the range of ...

Composite Dowels in Bridges - Efficient Solution
Advanced Materials Research, 2013The bridges are vital structures for the transport infrastructure; it is a fact that, in the last decades, composite bridges became a well-liked solution in many European countries as a cost-effective and aesthetic alternative to concrete bridges. Their competitiveness depends on several circumstances such as site conditions, local costs of material ...

Journal of Prosthodontics, 2002
Purpose This investigation examined what effect cement thickness had on retention of prefabricated endodontic dowels luted with a composite resin cement (Panavia 21 OP; J Morita, Irvine, CA) into canals previously obturated with gutta percha and a eugenol‐based sealer.Materials and Methods Sixty‐four single‐rooted teeth were decoronated, filed, cleaned,

Lining prefabricated dowel(s) with fibre reinforced resin composite
Australian Endodontic Journal, 2016The study evaluated the adaptation and push-out bond force of two different lined fibre dowels in oval canals. Dowel spaces were prepared in 30 obturated mandibular premolars with oval roots. The samples were divided into three groups (n = 10). The first group received non-lined fibre dowels (NL).

Optimization of composite dowels shape in steel-concrete composite floor
Composite Structures, 2019Abstract The paper contains a numerical analysis of a steel-concrete composite beam with a composite dowel. The connector is a contoured part of the web in a half of the steel section. In the first part of the work, the composite beam was analytically designed in accordance with PN-EN 1994-1-1 standard.

In vitro resistance of composite resin dowel and cores
Journal of Endodontics, 1988In the spectrum of treatment modes of endodontically treated molars, composite dowel and core systems are considered an alternative to the widely used cast dowel and core method. In a laboratory setting under oblique loading with a slowly increasing force, no significant differences between the tested composite dowel and core systems could be detected.

A composite dowel bridge in the Czech Republic
Steel Construction, 2016AbstractThe floods in the Czech Republic in the last few decades have resulted in a significant number of bridges having to be rebuilt. Unfortunately, the work meant long‐term traffic closures for railway bridges, coupled with significant costs for renovation and for providing alternative transport services.

08.60: Composite dowels in cracked concrete Experimental investigation
ce/papers, 2017ABSTRACTIn steel‐concrete composite girders, composite dowel shear connectors can be used to transfer shear forces between the concrete slab and the steel section. In comparison to other shear connectors the composite dowels offer increased strength capabilities, higher deformation capacities both in normal and in high strength concrete and offer an ...

Shear resistance of concrete dowels in composite slim‐floor beams
ce/papers, 2021AbstractSlim‐floor beams offer the significant advantage of shallow floor depths. When combined with deep profiled steel sheeting, for example, being able to route services in‐between the troughs provides flexibility. Despite their advantages, composite slim‐floor solutions are rarely used in buildings, partly due to the lack of codified rules and ...

Research on fatigue cracks in composite dowel shear connection
Engineering Failure Analysis, 2011Abstract Last year, extensive research was conducted on a modern type of continuous shear connectors – the composite dowel PreCo-Beam (2001) [1] and innovative composite constructions were designed and built. As this shear connection is to be applied mainly for bridges, problems concerning fatigue behavior arise Berthellemy et al.
