Over the past century, European countries have developed mature and extensive transportation infrastructure networks, in which bridges play a vital role. Their design is increasingly influenced by life-cycle multi-objective performance criteria, which comprise economic, environmental and social factors. Hence, the emphasis has shifted from new...

Since the early 2000s, different frameworks were set up to enable web-based collaboration in building projects. Unfortunately, none of these initiatives was granted a long life. Recently, however, the use of web technologies in the building industry has been gaining momentum again, considered some promising technologies for reaching a more...

In order to design structural details of bridges for fatigue, the current version of the Eurocode for steel structures recommends partial factors for fatigue resistance based on the consequences of failure and on the maintenance method. The safe-life method is used for details where local formation of cracks could rapidly lead to failure or for...

Commercial, ready mix stone repair mortars have often been applied in conservation practice for the restoration of natura! stone, brick and terracotta, over the last decades with varying success in terms of durability of the repair mortar itself and compatibility with the substrate. In this research, four commercial stone repair mortars,...

Although corrosion of reinforcement is a well-known issue for the construction industry, there are still open questions about some fundamentals of corrosion in reinforced concrete. These points include, among others, which are the most sensitive locations of the steel/concrete interface for pitting corrosion to initiate and to propagate. In this...

An existing theoretical model indicates that the behaviour of trapezoidal steel sheeting under combined web crippling and bending moment may be modelled by only the sheeting's compressed flange. Therefore, this paper presents finite element models that simulate only the compressed flange of the sheeting, applying a prescribed displacement field...

Viele der existierenden europischen Eisenbahn- und Autobahnbrkken erreichen ihre Nennlebensdauer ftir Stahlermdung, obwohl eine langere Nutzungsdauer angestrebt wird. Eine Meiglichkeit, die Nutzungsdauer gefahrlos zu verlkigern, besteht darin, die Brcken in krzeren Abstkiden auf Ermdungsrisse zu prfen oder zu uberwachen und eventuelle Risse zu...

It has been suggested that future generations of building regulations can become more risk-informed and performance based, and that development of the regulations and the risk bases that underpin them should occur within a socio-technical systems framework. To facilitate this, it is important for regulators and the market to understand and agree...

The demand of a risk-informed performance-based approach for fire safety is growing in the Netherlands. Various major incidents have initiated the need for an upgrade of fire safety regulations. All major stakeholders involved have noted that the existing regulations are limited and that a risk-based approach should be developed. The discussions...

Estimating and reducing uncertaintyin fatigue test data analysis is a relevant task in order to assess the reliability of a structural connection with respect to fatigue. Several statistical models have been proposed in the literature with the aim of representing the stress range vs. endurance trend of fatigue test data under constant amplitude...

As modern society is striving to become more sustainable and environmentally friendly, the need for more durable constructions with longer life cycles is increasing. On the other hand, the functional properties of constructions -such as pavements- need to remain at least at the same level or even outperform the current ones as higher quality...

The lack of resistance models to determine the penetration of airborne chlorides into the concrete makes service-life prediction hardly possible for concrete structures exposed to chlorides, something badly needed as airborne chlorides can lead to severe bar corrosion even at 10 km (6 miles) from the sea. Predicting chloride penetration...

Standards and guidelines for the fatigue design of riveted connections make use of a stress range-endurance (S-N) curve based on the net section stress range regardless of the number and the position of the rivets. Almost all tests on which S-N curves arebased, are performed with a minimum number of rivets. However, the number of rivets in a row...

Hydraulic structures like storm surge barriers are essential for water safety / flood protection. Hence it is important to keep them in operation in the most efficient way during its Life Cycle. A peer review is an asset management tool which has been developed within I- STORM (network of professionals on storm surge barriers) based on a tried...

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...

In recent years, the use of computational fluid dynamics (CFD) to evaluate flow fields has become more popular in various branches of industry. In building design, there is a similar trend towards the increasing use of CFD. There are several guidelines for CFD analysis of flows in the urban environment, e.g. [1-4]. For assessment of wind speed...
