Towards Multi Shape Morphing Structures

The bending stiffness of a structure is highly dependent on its shape, and this relation can be utilized to allow for a structure to morph into different shapes during deformation. This paper focuses on shape-morphing into multiple shapes (Multi Shape-Morphing), and presents a design method for a parametric<br/>structure consisting of beams,...

Parametric design of a grid shell roof over existing buildings​, with a focus on connection design

The motivation of the thesis relates to designing grid shells over existing buildings. Grid shell roofs are a way to enclose an existing space structurally efficiently and have minimal interference with the surroundings from an architectural and environmental perspective. The solution results in less material usage than shell structures, and...

Shape optimisation of a second skin: What can be achieved - in terms of structural and building physics performance - when an existing skin of a building is removed and replaced by a new facade

To reach the European Union climate targets of 2020 the rate of refurbishment must increase. The problem is that there are many barriers to refurbishment, which causes a low rate and low quality. The objective is to overcome these barriers and stimulate facade refurbishment. This thesis looks at the improvement, that can be made when replacing...

OPTIMUS: Self-Adaptive Differential Evolution with Ensemble of Mutation Strategies for Grasshopper Algorithmic Modeling

Most of the architectural design problems are basically real-parameter optimization problems. So, any type of evolutionary and swarm algorithms can be used in this field. However, there is a little attention on using optimization methods within the computer aided design (CAD) programs. In this paper, we present Optimus, which is a new...

Visual Analytics for Generative Design Exploration: An interactive 3D data envirionment for a computational design system facilitating the performance-driven design process of a nearly Zero-Energy sports hall

Improvement of design performances requires exploration of a larger amount of analyzed design solutions in the early design phase. Computational design systems use parametric modeling, building performance simulations and genetic algorithms to iterate through a large amount of design alternatives, converging towards optimal design solutions....

A Sound Working Environment: Optimizing the Acoustic Properties of Open Plan Workspaces Using Parametric Models

Optimizing the acoustic environment of open plan offices is a complex task due to the large number of design parameters that must be considered. In current practice, acoustic analysis – even in a simplified form – is not naturally integrated into the design process of office spaces. Applying digital acoustic simulation in architectural design...
