Zhang, Chi (author)
In recent years, the wind energy industry shows more and more interest in composite materials manufactured with a new process called pultrusion. The advantage of pultruded composite plates includes high fiber volume fraction, low price and simplified blade manufacturing. However, pultruded plates are fully cured and crosslinking is absent at...

Wind turbines are decommissioned when they reach their endoflife. The reason for reaching endoflife varies per wind turbine, but they all have in common that the wind turbine blades can not be recycled and thus end up as waste. Since a growing amount of wind turbines will reach their endoflife the coming decade, the waste problem will increase....

The concept of an innovative bonded joining technology where welding is not required is presented as an alternative to traditional welded connection for steel circular hollow section (CHS). Wrapped composite joints have potential to greatly improve fatigue endurance when applied in multi-membered truss structures, e.g. offshore jackets for...

Interest in composites for application in Civil Engineering structures, has seen significant increase in recent years. From composite repairs on existing structures from concrete or structural steel, to composite decks in bridges or even structures made solely out of fibre reinforced composites, the structural industry is following the already...

Free-form façades with bent glass have become increasingly popular in recent times. As bent glass is stiffer against out-of-plane loads, it can result in thinner glass and lower embodied carbon. A promising new technique is to cold bend thin glass plates with a stiff structural edge into a hyperbolic paraboloid (hypar), and to subsequently lock...

Fiber Reinforced Polymer (FRP) has increased rapidly in popularity in the past few decades. The material's advantageous properties, such as a high strength-to-weight ratio and low required maintenance, gave rise to its popularity in multiple major engineering branches. Buckling behaviour develops due to the notably low stiffness-to-strength...

Design and execution of fatigue load dominated circular hollow section (CHS) multi-membered structures, such as offshore jacket and floating structures for wind turbines, truss bridges, etc., is hinged on fatigue performance of critical welded joints. An innovative jointing technology of wrapped composite joint connects steel hollow sections by...

Verhoeven, Alexander (author)
In off-shore structures, the jacket foundations are mainly welded connections in circular hollow sections. These connections exhibit problems in resisting fatigue load. Wrapped composite joints tackle this problem with improved fatigue resistance. However, the material properties are yet unknown. In order to determine the properties on a more...

Design optimization of fiber-reinforced polymeric (FRP) composite products is essential to facilitate their applications in engineering structures. For bridge structures, the main design optimization goals are the reduction of FRP material consumption and the structure weight, which aim to reduce the initial construction cost and achieve a...

The use of hybrid and composite solutions for structural applications represents a common approach for the development of safe design principles. Consolidated examples exist for concrete, steel and masonry structures. As a general rule, materials are combined so as to obtain an enhanced redundancy, strength and/or (lateral) stiffness for these...

In this paper, analytical and numerical homogenization methods are proposed to effectively simulate the macroscopic characteristics of a pultruded composite lamina. A continuum damage model was implemented via user material subroutine to model fiber failure, while the Mohr-Coulomb plastic criterion is employed to model matrix damage. In order...

In order to evaluate the shear performance of sand-coated glass fiber-reinforced polymer (GFRP) perforated connectors (SCGPC) embedded in concrete, 8 pull-out tests were conducted. Finite element (FE) analysis considering GFRP failure and cohesion between GFRP and concrete of SCGPC were conducted for parametric analysis. Effects of surface...

Over the last two decades Fibre-Reinforced Polymer (FRP) constructions have infiltrated the infrastructure market, particularly in the Netherlands. This is due to the increased number of short-span pedestrian and cycle bridges which are used to traverse canals and waterways. FRP bridges are desirable as they are light-weight, require low...

The idea for Geometry matching by multi-agent systems as a subject originates at a previous course, where the J. Sturkenboom & author came up with an idea to use the material of old boat hulls as facade elements to provide a solution to an environmental problem. The approach then was rather practical, whereas the approach within this thesis...

We present a new approach to estimate geometry parameters of glass fibers in glass fiber-reinforced polymers from simulated X-ray micro-computed tomography scans. Traditionally, these parameters are estimated using a multi-step procedure including image reconstruction, pre-processing, segmentation and analysis of features of interest. Each...

This thesis focuses on the collaboration of two innovative materials - Fibre Reinforced Polymers (FRP) and structural glass – in the design of a (hybrid) footbridge with a 30 meter span. The choice of subject is led by a rising popularity of these materials in bridge design and strengthened by positive recent developments in conceptual small...

Over the past decade, wind turbine towers have grown taller and wider to support high capacity turbines. It may, therefore, be prudent to investigate materials alternative to steel to mitigate an increase in tower mass, cost, and complexities in transportation & manufacturing associated with the steel towers. The current research focuses on...

Glass is gaining popularity as a structural material, this is mainly based on its transparent character. But due to its brittle failure behaviour the safety of these structures is an issue. Several concepts are found to guarantee the safety during the development of its structural application. One of these developments is to reinforce glass with...
