Predicting the Best Stability System for High-Rise Steel Buildings by an Artificial Neural Network

Selecting the optimal stability framework for high-rise steel buildings is a critical decision that impact both economic efficiency and sustainability. This decision is not easy since there are many stability frameworks to choose from, such as tube, concrete shear-wall, and outrigger system. Designers and clients aspire to compare multiple...

Pre-Design Assessment of Demountable Short Superstructures

Rijkswaterstaat aims to build circularly from 2030 onward, with the purpose of having a fully circular economy by 2050. Therefore, the aim of this study is to design a reusable modular superstructure, with a small span, which can replace an existing so-called volstortligger superstructure. This is a structure that Dura Vermeer often uses and it...

Influence of Initial Mesh Topology on the Optimal Structural Design of Steel Space Frame Structures

Space frame structures today are a common choice of load bearing system for achieving long spans with minimal interruptions of the floor plan beneath. On top of that, the versatility of space frame structures to conform to any shape makes them particularly interesting today, especially in the context of free-form geometry which is becoming ever...

Balancing design and circularity: Optimizing the reuse of steel elements in the design of frame structures

The steel sector is responsible for 4-5% of the total greenhouse gas emissions in the world. Reusing structural steel elements can potentially decrease the need for the production of new steel. However, designing a load-bearing structure with reusable elements poses challenges to the design process. The starting point of the process is different...

Shadow cost optimization of the main bearing construction of industrial halls: Development of an optimization methodology for industrial halls that combines shadow price data with a structural parametric model and generative design

The purpose of this thesis is to determine the most optimal material use and configuration of structural elements with regard to minimizing shadow costs associated with the main bearing construction of industrial halls. Central themes in thesis are reusability, parametric modelling and generative design. <br/><br/>The construction sector is...

Multidisciplinary Design Optimization of Timber High-Rise: Research and Development of a Multidisciplinary Design Optimization Tool

There are two main challenges in the construction industry: carbon emissions and densification in cities. Timber high-rise might prove as a suitable solution to both these challenges. However, there is a lack of implementation of timber high-rise. This research argues that a lack of thorough analysis of timber design alternatives in the...

Computational Design Analysis of Height Scenarios in Residential High-rise under BENG 2020

In the Netherlands, the building sector accounts for more than one third of the total primary energy consumption. In response, new regulations, BENG 2020, are implemented and applied to all new constructions as of the 1st of July 2020. Regarding the high-rise typology that is known for its extensive energy consumption, those regulations present...

Topologically Optimised Cast Glass Shell: Topological optimisation and new fabrication methods for compressive free-form glass structures

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...

Patterned Grid-shell: Designing a method to analyze and compare grid-shells influenced by traditional lattice patterns of north Asia

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...

Computation design method for Statics-Responsive Grid Shells

Quadrangular Grid shells have generated interest in recent years for their application in rationalizing free form geometry in the built environment. Shell structure are efficient because their form is governed by flow of internal forces. But while discretizing shells into grid shells, instead of using flow of forces, current method follows...
