The new cable-stayed arch bridge Tegenbosch (Eindhoven, the Netherlands) needed an assessment of its dynamic behaviour under wind loading due to its slender design. Because of wind-induced vibration issues on a number of bridges in the Netherlands with similar designs, it was decided to examine if vortex excitation, wind-rain induced vibration,...

Multiphase flow through pipelines can result in severe pipe vibrations and fatigue damage. Commonly, finite element analyses are used to define the dynamic pipe stresses and calculate the lifetime of the piping. The fluid flow excitation forces can be estimated with analytical models or simulated in detail using computational fluid dynamics. If...

Three experimental campaigns were done at an industrial-scale test site to measure the influence of pressure on the forces induced by multiphase flow in process piping. For these different campaigns, measurements were done at 10, 25, 45 and 80 bar, involving different fluids (natural gas, MEG, oil, CO2) and different orientation of the test...

In CO2 storage plants, internal multiphase flow of CO2 may occur in piping elements in various parts of the process. From the energy and process industries, it is known that multiphase flow can induce high amplitude vibrations, especially in flexible piping. In the last decade, experimental data sets and results from excitation spectrum...

Multiphase flow is a known source of vibrations in piping systems. Multiple experimental campaigns have focused on the force spectrum on horizontal bend systems. To evaluate the evolution of multiphase forces through a vertical loop, experiments have been done on an air-water, two inch pipe system consisting of four bends at near-atmospheric...

For the modeling of stochastic structural responses due to wind gusts, reasonable assumptions for the aerodynamic admittance are elementary. However, still a large variety of corresponding models exists and it lacks of validation and reliable model estimation studies based on real-data. In this paper, real-data from a high-rise tower in...

Wind-induced vibrations are an important aspect in high-rise building design. The structural properties that influence vibrations are the mass and stiffness of the building and the foundation. These properties are difficult to predict in the design, resulting in inaccurate predictions of the dynamic response. As a first step towards better...

Earthquake site response is an essential part of seismic hazard assessment, especially in densely populated areas. The shallow geology of the Netherlands consists of a very heterogeneous soft sediment cover, which has a strong effect on the amplitude of ground shaking. Even though the Netherlands is a low- to moderate-seismicity area, the seis...

Comparison between in-situ measurements and design values of high rise dynamic characteristics shows that current way of predicting these values is inaccurate. The HiViBe project aims to develop models which provide for more reliable predictions of the dynamic characteristics and response of high-rise buildings. To that end, measurements are...

Multiphase flow can induce high amplitude vibrations in piping systems. Several experimental campaigns focused on the force spectrum on a single bend. To evaluate the evolution of the forces from bend to bend, experiments have been done on an airwater, one inch pipe system consisting of six bends at nearatmospheric conditions. In a first phase,...

A study was undertaken to define which set of signal characteristics can be used to differentiate between various vibration sources in a built environment. Several datasets of vibration measurements on known sources are obtained and analyzed. A set of 11 signal characteristics were determined for all signals. Based on the correlation between...

KM3NeT is a research infrastructure being installed in the deep Mediterranean Sea. It will house a neutrino telescope comprising hundreds of networked moorings — detection units or strings — equipped with optical instrumentation to detect the Cherenkov radiation generated by charged particles from neutrino-induced collisions in its vicinity. In...

A reliable damage diagnostic by ultrasonic guided wave (GW) based structural health monitoring (SHM) can only be achieved if the physical interactions between wave propagation, the SHM system and environmental factors are fully understood. The purpose of this research was to gain knowledge about the effects of high-amplitude low-frequency...

Demping is een belangrijke parameter in de analyse van het trillingsgedrag van hoogbouw. Met een beter begrip van demping kunnen modellen worden ontwikkeld waarmee het trillingsgedrag nauwkeuriger kan worden voorspeld. Met een nieuwe analysetechniek, genaamd Energie Flux Analyse (EFA) of energiestroomanalyse, kan de dempingsbijdrage van zowel de...

Flow-induced pulsations in flexible risers and flowlines (FLIP) has been the subject of ongoing research roughly over the last two decades. This phenomenon, also called singing, can cause high vibration and cyclic stress levels in the attached up- and downstream pipe systems, thereby imposing serious limitations on the flowrates through the...

Exposure to nocturnal freight train vibrations may impact sleep, but exposure-response relationships are lacking. The European project CargoVibes evaluated sleep disturbance both in the field and in the laboratory and provides unique data, as measures of response and exposure metrics are comparable. This paper therefore provides data on exposure...

The noise produced during a train pass-by originates from several different sources such as propulsion noise, noise from auxiliary equipment, aerodynamic noise and rolling noise. The rolling noise is radiated by the wheels and the track and is excited by the wheel and rail unevenness, usually referred to as roughness. The current TSI Noise...
