The Weakness of Robustness

Levee system reliability modeling The length effect and Bayesian updating

In levee system reliability, the length effect is the term given to the phenomenon that the longer the levee, the higher the probability that it will have a weak spot and fail. Quantitatively, it is the ratio of the segment failure probability to the cross-sectional failure probability. The literature is lacking in methods to calculate the...

The new dutch guideline for seismic foundation design in Groningen

Structural reliability of existing city bridges

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...

Reliability in the performance-based concept of fib Model Code 2010

The design philosophy of the new fib Model Code for Concrete Structures 2010 represents the state of the art with regard to performance-based approach to the design and assessment of concrete structures. Given the random nature of quantities determining structural behaviour, the assessment of structural performance cannot be well established by...

Numerical Modelling of Rain-Wind-Induced Vibration: Erasmus Bridge, Rotterdam

Shortly after completion, the main span cables of the Erasmus Bridge in Rotterdam showed aerodynamic instabilities with large amplitudes. These instabilities were recognised as rain-wind-induced vibrations. Temporary measures were installed on the bridge, and a year later, tuned hydraulic dampers were mounted as a permanent solution. The...

Report of the working group on dynamics

This review article was especially prepared for possible use of code designers. Its purpose is to frame standard dynamics problems and algorithms within classical structural reliability schemes. © 1997 Elsevier Science Ltd.
