Wirtschaftliche Verbundbauweisen im Brückenbau – Bauweisen mit Verbunddübelleisten

Abstract

Verbunddübelleisten bieten im Brückenbau ein breites Einsatzspektrum. Sie sind einfach herzustellen und stellen bei der Übertragung der Schubkräfte in der Verbundfuge eine dauerhafte und robuste Lösung dar. Aus der neuartigen Wirkungsweise ergeben sich neue Konstruktionen im Verbundbrückenbau. Der Aufsatz gibt einen Überblick über Konstruktion und Wirtschaftlichkeit ausgeführter Bauwerke mit Verbunddübelleisten.Economic composite constructions for bridges ‐ Construction methods implementing composite dowel strips. Composite dowel strips find a wide range of application in bridges. They are easy to manufacture and the transmission of shear forces of the composite action is long lasting and robust. Beside the innovative composite action new construction methods for composite bridges are established. The article summarizes already executed bridge structures implementing composite dowel strips due to construction details and economic aspects.

The model for a general composite section resulting from the introduction of composite dowels

“…16a); they are denoted with M-and M+ respectively. This was the case of the bridge in Tczew, for example, [21] (see cross-section in Fig. 15).…”

“…1. Bridges using composite dowels and their respective composite sections: a) bridge P11 constructed in Romania [21], b) bridge PE4 constructed in Poland [21], c) "Simmerbach" bridge constructed in Germany [22], d) bridge over the River Łososina in Poland [21], e) viaduct in Kuchl, Austria [21], f) viaduct WD4 on S5 road near Bydgoszcz, Poland [21] atively small compared with the longitudinal force T as long as the inclination angle remains relatively small. The inclination angle is deliberately denoted a, contrary to the inclination angle denoted θ in Eurocode 2 [30] -the value of an a angle is much smaller than θ, but, actually, both angles describe the same phenomenon, creating an important topic of current study.…”

“…The problem of a "smooth transition" from composite to concrete solution presented in Fig. 4 is reflected in a single girder in the bridge in Elbla˛g [40] and the PE4 bridge [21]. In the case of the bridge built in 2016 south-west of the city of Elbla˛g in Poland, two types of composite section were used for the internal spans ( Fig.…”

The Experimental Research on Special Polymerized Sulfur Composite- Impregnated Concrete and Cement Mortar

“…It depends on humidity and on concentration of compounds which make electrical conductivity of the condensate to increase and react chemically (battle chemicals and the battle relationship) with after that they have dissolved in it [59][60][61][62][63][64][65][66].…”

“…It was prepared by melting special polymerized sulfur at the tempera ture 150-160 o C and then by cooling to the ambient temperature [56][57][58][59][60][61][62][63][64][65][66][67].…”
