Borgart, A. (author)
Shell structures can be either calculated with complex mathematics and differential geometry, or with the help of finite element method (FEM) software. Neither method gives the designer sufficient insight about the behaviour of the shell in the early design stage. The first method is for most designers too complex, it requires proficiency in at...

Pavlidou, Stella (author)
In an urban context that needs to be constantly adapted to global crises, population movements, climate change and economic crises, designers and engineers strive to configure solutions that respond to multiple criteria. Within this framework, the concept of generative design is gaining more and more ground in the construction field, allowing...

Shell structures carry loads with their thin yet curved shapes. Being thin means shells require little material, which is desirable for minimizing embodied carbon footprints. However, the feature of being curved implies shells require immense effort to design and fabricate. To address the challenges, this dissertation consists of three parts:...

Implementing parts per billion-level nitric oxide (NO) sensing at room temperature (RT) is still in extreme demand for monitoring inflammatory respiratory diseases. Herein, we have prepared a kind of core-shell structural Hemin-based nanospheres (Abbr.: Hemin-nanospheres, defined as HNSs) with the core of amorphous Hemin and the shell of...

This paper investigates the correlations among 3D graphic statics, Maxwell–Rankine stress function, and Pucher's equation (the governing equation of membrane shells). When there is only vertical load, a solution of Pucher's equation can be converted into a Maxwell–Rankine stress function. The resulting stress function can be further...

A new approach to applying the finite difference method for solving the shell model problem. By solving the general shell differential equations (Sanders-Koiter equations) with first-order finite-difference approximation only, a finite difference algorithm called shell code has been developed. <br/><br/>To this end, a 1200-line Python program...

Flapping Wing Micro Air Vehicle (FWMAV) technologies are emerging due to the vast number of applications that they can be utilized in. Researchers and scientists are constantly seeking to push the boundaries to the extreme in terms of miniaturization of this technology, making it smaller, lighter and better performing. In order to achieve this...

An alternative option to the traditional grouted joint for wind turbines is a direct steel-to-steel connection, also known as slip joint. In a recently published work, a proof of concept of a vibration-assisted installation and decommissioning technique of a slip joint was illustrated. Leveraging on the obtained results, the current study shows...

When designing for structural performance, the geometry of the load-bearing elements is crucial for achieving the required stability. This is even more important in structural forms, such as shells and arches that are predominantly designed by their structural requirements. However, the typical design process starts with the design by the...

Glass is a material which can be seen as a double-edged sword. Its monolithic, smooth, and transparent look transmits a sense of elegance and simplicity. However, due to its brittle mechanical property, it can create complex engineering challenges when intended for a structural load-bearing application. Many forget glass has a comparable...

This thesis aims to explore various possibilities in grid-structures by introducing atypical line geometries and examine its feasibility in a built environment. The proposition is derived from the larger purpose of adapting native design characteristics in modern built environment. Focusing on the Asian context, one of the essential...

TCompared to flat sheets of float glass, cast glass components have a thicker geometry and thus a high buckling resistance. This buckling resistance in combination with the high compressive strength of glass make cast glass components suitable for the construction of fully transparent shell structures that are mainly subjected to compressive...

This paper presents a detailed structural analysis of a bubble shell engineered by Heinz Isler. Through 3D scanning the geometry of this shell structure has become available to the authors. Structural analysis has not been possible before since the geometry of the shell was not available. The bubble shell was Isler’s most built type of shell. In...

Cast glass is a promising structural material that has seen increasing use in the build environment over the last year. It offers a great freedom of shape for designers and engineers, beyond the two-dimensional float glass that is still primarily used. Despite this, cast glass in practice has only been used for solid bricks, mimicking...

Glass is a material that has a high compressive strength and a low tensile strength. While being mostly produced as flat sheets of float glass, it can also be casted into components that have a thicker geometry and thus a higher buckling resistance. These properties make cast glass components suitable for the construction of shell structures...

This thesis aims to provide a better understanding on the relationship between the mechanical and geometrical properties of shell structures. In search hereof, an attempt is made to describe the thrust surface; a geometrical representation of the in-plane force trajectories through a structure. There exists a well-known relation between the...

One of the geometrical restrictions associated with printed paste materials such as concrete, is that material must be self-supporting during printing. In this research paper a new methodology for 3D Printing Concrete onto a temporary freeform surface is presented. This is achieved by setting up a workflow for combining a Flexible Mould...

Shell structures have been regularly used in the past for creating huge spanning structures, with the use of minimal material. Even though this method saves a lot of material, the labor cost of constructing these structures is high, due to the amount of work on the building site. By prefabricating these structures, a huge amount of labor and...

Shell structures appear quite often in our daily life. From aircraft fuselages to storage silos and boat hulls, these structures are employed for their structural efficiency and the aesthetics they provide. They are characterised by a small thickness in comparison to their other dimensions and by curvature in their unstressed state. Despite...
