“…Many of these models have been documented in the literature by, for example, Sinha et al (1964), Karsan and Jirsa (1969), Buyukozturk and Tesng (1984), Yankelevsky and Reinhardt (1987a), Chang and Mander (1994), Bahn and Hsu (1998), Elmorsi et al (1998), Palermo and Vecchio (2003), Mansour and Hsu (2005) and Sima et al (2008). Most refer only to the compressive cyclic behaviour of concrete and only a few consider the cyclic tension response.…”

“…All the model parameters were statistically derived from tests developed by other authors. Sima et al (2008) developed a constitutive model for normalstrength concrete subjected to cyclic loading in both compression and tension. Particular emphasis was paid to the description of the strength and stiffness degradation produced by the load cycling in tension and compression, the shape of unloading and reloading curves and the transition between opening and closing of cracks.…”

“…Some combinational models based on plasticity and fracture mechanics theory have also been developed. Although plasticity and fracture mechanics models can correctly simulate the observed behaviour of concrete, their application in engineering practice is limited due to the great amount of parameters usually needed and the difficulty in obtaining them through conventional laboratory tests (Sima et al, 2008).…”

A hysteretic stress-strain model is developed for unconfined concrete with the intention of providing efficient modelling for the structural behaviour of concrete in seismic regions. The proposed model is based on the findings of previous experimental and analytical studies. The model for concrete subjected to monotonic and cyclic loading comprises four components in compression and tension -an envelope curve (for monotonic and cyclic loading), an unloading curve, a reloading curve and a transition curve. Formulations for partial unloading and partial reloading curves are also presented. The reliability of the proposed constitutive model is investigated for a reinforced concrete member using a non-linear finite-element analysis program. Comparisons with test results showed that the proposed model provides a good fit to a wide range of experimentally established hysteresis loops.

“…It contains reinforcement bars and both materials have their own nonlinear stress-strain relation. In the past much research has been done to investigate the stress-strain relation for reinforced concrete and Sima [1] has published a bi-linear formula (1) to calculate the concrete stress-strain relationship. Since all concrete infrastructures built in the Netherlands are designed according to the rules of NEN-EN 1992-1-1 [2] (or earlier codes), this code is also used as a basis for designing the simple model as presented in this paper.…”

Eddie Koenders received his MSc and PhD degree from Delft University of Technology. His research area is multi-scale and multi-disciplinary modeling in view of sustainable infrastructure. He is chairman of the STW IS2C Perspective program and professor at the NUMATS sustainability center at COPPE-UFRJ, Brazil. SummaryConcrete infrastructures are mostly designed for a service-life of eighty to hundred years. During this service life these structures are loaded by traffic and environmental actions which affect the structural and material induced degradation mechanisms. In the last fifty years, the traffic intensity has increased significantly, i.e. heavier vehicles passing at higher frequencies and at higher velocities, initiating an increased number of local damage types to many infrastructures. In addition, damage caused by material degradation mechanisms such as chloride ingress, ASR and local degradation mechanisms have increased as well. These processes have turned out to reduce the expected service-life of concrete infrastructures to a large extend. In order to assess the effect of structural and material degradation on the performance of infrastructure a simply supported beam has been developed with the aim to include dominant material and structural related degradation phenomena. In this first order approach, the effect of the on-going hydration of compression strength, creep and the effect of stochastic traffic loads on bridge structures have been taken into account while the degradation mechanisms such as ASR and chloride ingress have not been explicitly modelled yet. In this model the influence on the strength capacity and stiffness is calculated and the effect on the bridge performance is evaluated. With the knowledge acquired from this simplified model, in the coming years, a more realistic model will be developed which also accounts for the material degradation mechanisms. The model will be validated with real time data archived from the Hollandse bridge monitoring system.

Abstract. In the paper, experimental results of tension member tests are used as a basis from which to develop an extended tension stiffening model for reinforced concrete, with emphasis on the specific concrete damage and the developments of residual deformations depending on the structural loading. Two characteristics are contained in the proposed model: one describes the residual deformation behaviour along the reinforcement accounting for the cracks that cannot be closed completely, while the other describes the degradation of the concrete stiffness. Within context of non-linear analysis, the model is incorporated into an analytical approach, based on the LAGRANGE principle of minimum of total potential energy. The mechanical problem is solved with the application of the mathematical optimisation, using energy principles formulated as a kinematic formulation and transforming them into non-linear optimisation problems. It was demonstrated, that this approach is eminently suitable for analysing pre-damaged or pre-loaded reinforced concrete crosssections under cyclic loading.
