Article
Fiber-reinforced concrete (FRC) structures are mainly designed using finite-element software. The input parameters used in these methods are based on the material properties of FRC obtained from test results. Because the experimental results of FRC show huge deviations, the material properties determined by an ordinary number of experiments do not...
Article
This article shows through the analysis of three independent tests that the presented new semidiscrete analytical (SDA) beam model is efficiently applicable in the evaluation of test results. The model is based on fracture mechanics, takes the real distribution of the macrofibers into consideration in the critical cross-section of the beam, and use...

The use of fibre reinforced concrete has significantly increased in recent years. Despite a considerable amount of research, fibre reinforced concrete (FRC) has not been standardized yet. The aim of the present survey is to work out a new semi-discrete beam model which takes the real distribution of the fibres in the critical cross-section of the F...
Article
Full-text available
The pull-out behaviour is one of the distinctive features of fibre reinforced concrete. Few analytical models for the pull-out of synthetic fibres can be found in the literature. Moreover, the existing models are not supported by comprehensive experimental investigations. In this research experimental investigations have been carried out. First, th...
Article
In recent years, fiber reinforced concrete has been increasingly used not only for industrial floors but for many other loadbearing structures as well. The different types of synthetic fibers have distinct effects on concrete: micro fibers to reduce plastic shrinkage cracking of concrete, and macro fibers to give higher fracture toughness. This pap...
Article
In the design of composite sections, beam theories are used which require the knowledge of the cross-sectional properties, that is, the bending-, the shear-, the torsional-, warping-, axial stiffnesses and the coupling terms. In the classical analysis, the properties are calculated by assuming kinematical relationships (e.g. cross sections remain p...
Article
Composite beams and columns are analyzed and designed either with explicit beam expressions or with numerical (e.g. FE) methods, both require the knowledge of the cross sectional properties, i.e. the bending-, the shear-, the torsional-, warping-, axial stiffnesses and the coupling terms. These properties are calculated either by using kinematical...
Article
The paper presents a theory for thin-walled, closed section, orthotropic beams which takes into account the shear deformation in restrained warping induced torque. In the derivation we developed the analytical (“exact”) solution of simply supported beams subjected to a sinusoidal load. The replacement stiffnesses which are independent of the length...
Article
The paper presents the summary of beam theories of thin-walled open and closed section composite (fiber reinforced plastic) beams and columns which take into account both the transverse and the torsional shear deformations. Simple expressions are presented to determine the cross sectional properties required in the solution of practical problems su...
Article
A beam theory for open and closed section, thin-walled, composite beams is presented. The layup of each wall segment is arbitrary, the effects of shear deformation and restrained warping are neglected. Closed form expressions are developed for the calculation of the 4×4 stiffness matrix. It is also shown that the local bending stiffnesses of the wa...
Article
Full-text available
This paper compares the results of different beam theories with finite element calculations and determines simple rules which designers may apply to insure simplified theories give acceptable results. Specifically, we analyze the effect of shear deformation and restrained warping. For thin-walled beams with layups that may be symmetrical or unsymme...
