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...

Full probabilistic reliability analysis may be valuable for assessing existing structures. Measures for increasing the safety level are quite costly for existing structures and may be unnecessary when such a decision is grounded on a conservative analysis for determining the structural reliability. This may be avoided by applying a more detailed...

The new generation of tall buildings is higher and more slender than the buildings built before. Additionally, increased use is made of high-strength materials which have a higher strength yet the same stiffness properties as conventional materials. Both aspects increase the sensitivity of tall buildings to dynamic behaviour. The design has to...

Since 1992 there have been a number of proposals to renew calculation methods available to assess the structural safety of existing buildings. But without operational results. Upon publication of the Eurocodes NL decided to renew and to include them in the Dutch building regulations. The question was how. One decided to develop a new Dutch...

Part 1-7 of EN 1991 covers accidental actions and gives rules and values for impact loads due to road, train and ship traffic and loads due to internal explosions. In this paper, the application of Part 1-7 of EN 1991 for steel structures is explained. Background information and design strategies are given. Also some application examples are...

Tunnels and other underground structures are designed for lifetimes of at least 50 to 100 years. A tunnel can probably last even longer from a technical point of view, providing the original functionality it is designed for does not change too much. In order to avoid high maintenance costs a careful design procedure is necessary. For this kind...

In the past decades an impressing and useful set of operational methods for probabilistic structural analysis has been developed. Based on SAFRELNET activities in Task 5.1 the paper provides a structured discussion of these methods and indicates the various fields of application. The Level II time-independent component-reliability methods (FORM...

The main reason for the existence of civil infrastructures is public interest. Therefore, various societal aspects should drive an infrastructure program. Civil infrastructures are long-lived as-sets. Bridges and other structures are designed for lifetimes of 50 to 100 years. A bridge can last much longer from a technical point of view,...

In recent years an advanced program for reliability analysis of dike systems has been under de-velopment in the Netherlands. This paper describes the global data requirements for application and the set-up of the models in the Netherlands. The analysis generates an estimate of the probability of system failure and an indication of the...

The JCSS Probabilistic Model Code (JCSS-PMC) has been available for public use on the JCSS website (www.jcss.ethz.ch) for over two years. During this period, several examples have been worked out and new probabilistic models have been added. Since the engineering community has already been exposed to the aims, structure and original contents of...

A reliability based code calibration procedure is a two step procedure. In the first step target reliabilities are set on the basis of experience or optimisation and in the second step corresponding partial factors and other safety elements (e.g. PSI-values as in Eurocode 1) are derived. This paper illustrates the use of the JCSS Probabilistic...

Load combinations specified in EN 1990 for verification of ultimate limit and serviceability limit states in conjunction with the partial factor method are discussed and illustrated by practical examples of typical civil structures. Alternative procedures to identify critical load cases are reviewed. Actions, load cases determined in accordance...

Due to a variety of physical and chemical processes, concrete bridges as well as other civil engineering structures deteriorate and may reach, after some time, a minimum acceptable level of performance. At that point in time maintenance (including inspection, repair and replacement) has to be carried out to avoid that the structure has...

After the introduction of reinforced concrete it was believed that the material was extremely durable. Soon it was found however, that reinforced concrete could have serious durability problems and that special care should be taken to avoid them. Durability became an issue.
