Testing for the chloride threshold (also called critical chloride content) for corrosion initiation of steel in concrete has been found difficult and, at best, time consuming. Nevertheless, the chloride threshold is an important parameter in service life design of new structures and for evaluation of the remaining service life of existing...

Portland cement production is an energy-intensive process responsible for a significant share of the total CO2 production. Its replacement with low carbon binders from by-products of industrial processes is a sustainable alternative for innovative construction materials. In addition, the combination of low carbon binders with recycled aggregates...

Volcanic tuffstone from the Eifel region, Germany, is one of the most important kinds of natural stone used in the Netherlands. These tuffs have, albeit with several hiatuses, been used since Roman times. At several places, original Medieval stones are still present. That does not imply that the stone is completely resistant to weathering: ' The...

This paper investigates the differences in the predicted fatigue life of transverse butt weld joints and cover-plated beams considering statistically based fitting methods on fatigue test data and comparing the results with the S-N relation proposed in international standards. The test data fitting are performed by employing the Least Square...

In a BIM data flow, an essential part of the coordination between disciplines is the agreement on recesses and openings in building elements. Different disciplines will request recesses and openings in elements that are managed and maintained by others. Using the full dataset of the elements has proven to be inoperable because of the information...

In-situ load testing of reinforced concrete (RC) structures is often performed to confirm the presence of the required resistance for the intended use (Conformity Load Testing) or to support the assessments of the residual capacity by models (Supplementary Load Testing for Condition Assessment). When performing an in-situ load test, one of the...

This paper discusses the development and first testing of a valid, reliable, functional and simple indicator, that represents the long term effect of short term decisions. Such an indicator can assist counteracting short term views in network level asset management decision making. Short-termism or myopia may occur in cases where service level...

Different analytical models exist to predict the shear strength of reinforced concrete members. Generally, each of these shear strength models consists of a formulation based on certain underlying theory and fitted model coefficients. The model fitting parameters are usually established from the comparison with test data. Hence, the predictive...

Asset managers would benefit from knowing when to expect corrosion initiation in a particular reinforced concrete structure. However, accepted approaches to test existing structures for the remaining time to corrosion initiation are lacking. This paper proposes such an approach, based on experience in the field and additional considerations....

Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a risk analysis, where necessary, shall be carried out. In the Netherlands, the risk of death for road users in a tunnel is calculated with a model for quantitative risk analysis, which is called “QRA-tunnels”. QRA-tunnels is...

The accuracy of predictions of structural behavior by finite element analysis strongly depends on the formulation of the numerical model. Depending on the problem at hand, the analyst has to make a number of choices, which influence the numerical results to a greater or lesser extent. For complex cases, e.g. existing reinforced concrete...

The KGO mixing method was developed 40 years ago. Instead of adding the bitumen at the end of the mixing cycle, the bitumen was poured down first together with the larger aggregates. After mixing the bitumen with the larger aggregates, the reamining aggregates were mixed down. As benefits of the KGO method were mentioned improving the...

For many concrete infrastructural works a service life of 80, 100 or 200 years is required. To convince owners and authorities that these requirements can be met probability-based models for service life predictions have been developed. These models are based on theoretical and experimental laboratory studies. Many of these models focus on the...

Clause 6.2 of EN 1993-1-1 covers the cross-sectional resistance of steel sections. The bending-shear interaction design rules for I-shaped cross-sections make use of a reduced yield stress for the web area. On this basis, a reduced design plastic resistance moment allowing for the shear force is presented. The effect of shear on the bending...

Modular expansion joints constitute a substantial part of direct and indirect costs of bridge maintenance. Joint condition assessments can be improved to predict or detect damages earlier. In this way the probability for consequential damages such as emergency repair and a shortened lifespan is reduced. Maintenance can be planned well in advance...

In the Netherlands civil engineering structures, such as overpasses, bridges and tunnels are generally built using blast furnace slag cement (BFSC, CEM III/B) concrete, because of its high resistance against chloride penetration. Although the Dutch experience regarding durability performance of BFSC concrete has been remarkably good, its...

Occasionally, a profound but distant connection between volcanos and culture exists. This is the case for the volcanic Eifel region in Germany and historic construction in the Netherlands, with the river Rhine as physical and enabling connection. Volcanic tuff from the Eifel comprises a significant amount of the building mass in Dutch built...

Quality control during the construction process is one of the determining factors that governs the service life of an asphalt road. In CONSISTEND a predictive tool is developed that objectively determines the effect of quality control during the construction processes on the life span of surface courses of asphalt roads. The tool predicts the...
