The main bottleneck during the manufacture of complex geometry thin-walled GFRC structures is the time taken to make the timber or CNC machined moulds for each panel. Complex geometries are comprised of many unique panel forms and the extensive time and high costs of their manufacture often prevents their architectural intent from being fully...

Photovoltaic (PV) technology is the most promising renewable energy source to be integrated on urban building surfaces. Modeling and simulating urban PV systems pose more challenges than the conventional ones installed in open field due to rich urban morphology. Herein, a comprehensive workflow to estimate urban solar PV potential is...

Shallow jet flows are often coupled to high flow velocities and complex flow patterns. To properly ensure the stability of the barrier between both water bodies surrounding the jet, a scour analysis is often a necessity. Such analyses are inevitably coupled to the hydrodynamic processes occurring in jet flows, either in the form of loads on...

Designing energy-efficient facades can have a significant impact on reducing the building's energy consumption while providing comfort for the occupants. While highly-insulated buildings have good thermal insulation and high airtightness, they deal with the risk of overheating issues. Dynamic insulation, a technology consisting of porous...

The fatigue strength of the pin connection is assessed in the research project presented in this thesis. The fatigue strength is quantied by an estimated fatigue lifetime, which is the expected time to failure of the most critical point in the connection. The lifetime is estimated based on the yearly accumulated fatigue damage. A computer model...

The Utility Lagrangian and the Surplus Hamiltonian in economic engineering do not depend on consumption.<br/>Two theories are proposed to include the effect of consumption in the Utility Lagrangian and the Surplus Hamiltonian. The second of these two theories resolves the dissipation obstacle in port-Hamiltonian systems as an additional result....

The idea for Geometry matching by multi-agent systems as a subject originates at a previous course, where the J. Sturkenboom &amp; 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...

Throughout the long history of architecture, the effect of gravity is always present in any structures. Surprisingly in tensegrity composition, this primary law of nature seems to be absent. This is because the discontinuous set of struts in the continuous network of proportionally thin cables makes the structures look like floating in the air....

Glass Fibre Reinforced Concrete (GFRC) has been developed over the last 50 years into the material it is today. GFRC is mostly used as a cladding material and to a lesser extent for structural elements. This paper examines the challenges of using freeform thin-walled GFRC elements in the design and fabrication of a self-supporting artwork. The...

The production of precast, concrete elements with complex, double-curved geometry is expensive due to the high costcosts of the necessary moulds and the limited possibilities for mould reuse. Currently, CNC-milled foam moulds are the solution applied mostly in projects, offering good aesthetic performance, but also resulting in waste of material...

The production of architectural elements with complex geometry is challenging for concrete manufacturers. Computer-numerically-controlled (CNC) milled foam moulds have been applied frequently in the last decades, resulting in good aesthetical performance. However, still the costs are high and a large volume of waste is produced. This paper...

Free-form buildings tend to be expensive. By optimizing the production process, economical and well-performing precast concrete structures can be manufactured. In this paper, a method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single element. The...

Free-form buildings tend to be expensive. By optimizing the production process, economical and wellperforming concrete structures and elements can be manufactured. In this paper, an innovative method is presented that allows producing highly accurate double curved-elements without the need for milling two expensive mould surfaces per single...

In an earlier article (CPI issue of August 2011 [1]) a method was presented for producing precast curved panels with a thickness of a few centimeters using the 'flexible mould method'. This method is the central theme in the PhD study of the first author on the realization of freeform architecture in concrete. The concrete panels manufactured...

This paper presents a computational strategy and parametric modelling toolbox which aim at enhancing the design- and production process of reinforcement in freeform curved surface structures. The computational strategy encompasses the necessary steps of raising an architectural curved surface model of a concrete building to production level in...

Due to the complexity of the freeform shapes it is often not possible to distinguish any repetitive elements in freeform buildings at all. Most freeform building designs consist of many single or double curved surfaces which require complex shapes for the mould and element edges. Since the costs of the moulds (formwork) for precast concrete make...

Population growth and immigration increase the demand for mass housing developments all over the world. These developments are widely criticized for being mono-functional, mono-typological, and mono-cultural. This project is a design method for a new kind of mass housing. All design rules are reformulated as algorithms, that interact with each...

The need to predict flow and heat transfer problems requires a flexible and fast tool able to simulate complex geometries without increasing the complexity of the flow solver architecture. Here we use a finite volume code that uses a direct solver with pressure correction. A new immersed boundary method (IBM) is used for a geometry consisting of...

We present a new Cartesian grid method for the computation of incompressible viscous flows in irregular geometries. The irregular boundary is implicitly represented by its signed distance function (the level-set function) and, by using level-set calculus tools, we are able to preserve the Cartesian structure of the discretized Navier-Stokes...
