The present research deals with the cyclic and standard pull-out resistance of deformed steel bars embedded in lightweight and normal concrete. This paper is a continuation of a previous paper, where the experimental results are detailed. In the present paper, the experimental results are set against the formulas and the diagrams provided by the Eu...

The topic of present research is the experimental investigation of pull-out resistance of B500B-type ribbed reinforcing steel bars embedded in lightweight aggregate concrete (LWAC) under unidirectional cyclic loading. Only a limited amount of standardized data on bond strengths are available in the case of cyclic loading, especially for lightweight...

The bond-slip relationship between concrete and steel is significant in evaluating the nonlinear behavior of reinforced concrete structures. The force transmitted by the bond in reinforced concrete structures was studied numerically in high-strength, lightweight concrete with ribbed reinforcing steel bar or seven-wire strand, using ATENA 3D softwar...

Perfect bond between concrete and reinforcement, which is described by the bond-slip curve, is the basic assumption for reinforced concrete structures. When using special or new materials, detailed, experimental verification is necessary to thoroughly characterize the bond-slip behaviour. The fib Model Code 1990 (MC1990) and 2010 (MC2010) as well a...

The paper deals with the assessment of damage in a lightly reinforced concrete beam using the measured values of the first natural frequency. The aim of the presented laboratory experiment was the experimental investigation of the relationship between the degree of cracking and the first natural frequency under defined deterioration conditions. As...

This paper deals with the circumstances of application of high-strength concrete in the Hungarian bridge construction industry in the mirror of adopting the Eurocode series. As a historical background, first a comparison has been carried out analysing the safety level of concrete bridge structures designed according to the Hungarian codes through t...
