Wind load estimation and virtual sensing in long-span suspension bridges using physics-informed Gaussian process latent force models

Wind loading is an essential aspect in the design and assessment of long-span bridges, but it is often not well-known and cannot be measured directly. Most structural health monitoring systems can easily measure structural responses at discrete locations using accelerometers. This data can be combined with reduced-order modal models in Kalman...

Optimization of complex-geometry high-rise buildings based on wind load analysis

As technology advances, architects often employ innovative, non-standard shapes in their designs for the fast-growing number of high-rise buildings. Conversely, climate change is bringing about an increasing number of dangerous wind events causing damage to buildings and their surroundings. These factors further complicate the already...

Optimisation of Complex Geometry High-Rise Buildings based on Wind Load Analysis

Wind analysis for the structure of buildings is a challenging process. The increasing strength and frequency of wind events due to climate change only add higher demands. In addition, high-rise buildings are growing in number and include many of unconventional shape. Current methods used in practice for calculating structural wind response...

Optimisation of complex geometry buildings based on wind load analysis

One result of climate change is the increasing strength and frequency of wind events. This creates a problem for the also increasing number of high-rise buildings many of which are of unconventional shape. However, current methods for calculating wind response either do not account for these geometries, such as the Eurocode or are prohibitively...

Estimation of the dynamic response of a slender suspension bridge using measured acceleration data

Suspension bridges with very long spans and slender designs are susceptible to large-amplitude dynamic excitation. Monitoring systems installed on bridges can provide measurement data (e.g. accelerations) and therewith valuable information on the true dynamic behaviour. This pilot study examines the possible use of recently developed methods...

Feasibility study of Air Traffic Control Towers around the globe: “International research regarding the local influences providing an optimal structural design for air traffic control towers around the globe in an economical perspective”

At this moment the global human wealth is getting to the next level, which means a growing amount of people is able to travel by plane and these growth figures are seen in the latest global annual passenger’s flows. These latest developments demand building new airports and extending the existing airports heavily around the world in the nearby...

Smart Wind Designing

A research on finding a method to integrate the wind engineering process to the design process. Wind engineering is seen to be a rigid and slow process of CFD modeling and wind tunnel testing. New frames of work and data analysis make it possible to integrate this process in the, much faster, design process. Proof of this integration is given in...

From adaptive to high-performance structures

Multiple design aspects influence the building performance such as architectural criteria, various environmental impacts and user behaviour. Specific examples are sun, wind, temperatures, function, occupancy, socio-cultural aspects and other contextual aspects and needs. Even though these aspects are acknowledged to be variable, conventional...

Fatigue life prediction and strength degradation of wind turbine rotor blade composites

Wind turbine rotor blades are subjected to a large number of highly variable loads, but life predictions are typically based on constant amplitude fatigue behaviour. Therefore, it is important to determine how service life under variable amplitude fatigue can be estimated from constant amplitude fatigue behaviour. A life prediction contains...

Simulation of fluid-structure-interaction with free form membrane structures using an implicit coupling scheme with adaptive under relaxation

Due to their special load carrying behavior, membrane structures are using the material most efficiently. As a consequence, the realized structures are extremely light but susceptible to flow induced effects. The missing bending stiffness results in a complex coupling of stress state and membrane shape. This necessitates special form finding...
