Determination of Stiffness of the Connections of Composite Steel and Concrete Bridge Deck by the Limit Permissible Deflections

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2013
The composite steel and concrete structures are used for constructing bridge floors and others buildings. The joint action of composite structures as well as their economic efficiency depends on the connection between the layers, i.e.

Influence of Concrete Shrinkage on the Behavior of Carbon Short-Fiber-Reinforced Concrete (CSFRC) under Tension

open access: yesApplied Sciences, 2023
Carbon short-fiber-reinforced concrete (CSFRC) is a novel material obtained by adding and mixing carbon fibers into fresh concrete. In this way, the concrete behavior is changed, and concrete no longer undergoes brittle failure under tension ...

Influence of plastic tension chord deformation on the shear capacity of prestressed beam elements

open access: yesActa Polytechnica CTU Proceedings, 2022
The shear strength of prestressed beam elements is of great interest with regard to the evaluation of existing concrete bridges. Accompanying extensive experimental test series, the adaptation and modification of existing models for the evaluation of the

Calculation Model for Steel Fibre Reinforced Concrete Punching Zones of Bridge Superstructure and Foundation Slabs

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2011
The usage of steel fibre reinforced concrete in monolithic joins is well known as a good alternative of additional reinforcement because of chaotic distribution of steel fibres in complex stress ant strain state. Unfortunately, the analysis of well known
