Analysis of Deflections of Bridge Girders Strengthened by Carbon Fibre Reinforcement

open access: yesThe Baltic Journal of Road and Bridge Engineering, 2008
The paper deals with experimental and theoretical investigations in reinforced concrete structures strengthened with carbon fibre sheets. Four stages in the behaviour of concrete structures strengthened with the carbon fibre reinforced polymer (CFRP) are

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.

Assessment of structures repeatedly exposed to thermal loading and extinguishing water: a case study of a firefighting training facility

open access: yesActa Polytechnica, 2023
When designing a new structure or assessing an existing one, the risk of fire and its effect on the structure must be considered. Structures are usually assessed for fire resistance at the design stage – i.e. before the possible exposure to fire.

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

Nonlinear Model of an Additional Concrete Head and its Comparison with Long-Term Measurements

open access: yesSlovak Journal of Civil Engineering, 2018
An additional concrete head or drop panels are not common solutions for strengthening flat slabs and have not yet been an adequately studied solution in the field of laboratory research.

A multi-level interface model for damaged masonry [PDF]

open access: yes, 2013
The aim of the present work is to propose a new micro-mechanical model in the context of the deductive approach used to derive interface models. This model, based on a previous study introduced previously by A. Rekik and F.

A model for strength and strain analysis of steel fiber reinforced concrete / Betono, armuoto plienine dispersine armatura, stiprio ir deformaciju apskaiciavimo modelis

open access: yesJournal of Civil Engineering and Management, 2011
The article proposes a model for strength and stain analysis of steel fiber reinforced concrete (SFRC). The model is based on general principles for creating and modelling structural composites and on reinforced concrete code.
