Minimising Embodied Carbon in Concrete Floors
… the embodied carbon of steel-reinforced concrete floors. Four interconnected optimisation studies are illustrated in this thesis: (1) shape optimisation of reinforced concrete beams using a parametric design approach to achieve practical and technically feasible solutions, considering deflection …

Thin-shell Concrete Floors for Sustainable Buildings
… material in a typical building exists within the floors, making these a prime target for material reductions. This dissertation shows that thin shell concrete floors are a viable alternative to typical slabs and beams in multi-storey buildings. Switching the dominant structural behaviour from …

Vibration Serviceability of Long Span Slender Floors
The modern trend towards long slender floors has led to major vibration serviceability issues in building floors under rhythmic loading. This happens as a result of reduced natural frequencies and damping ratios due to reduced structural rigidity (Devin et al, 2015). Even though these vibrations do …

Optimization of composite floors : theory and practice
In this paper optimized weight values for a composite metal deck floor system are compared to existing buildings to evaluate current industry performance in regards to material efficiency in steel structures. This comparison is made to demonstrate how optimization can be used to reduce material …

Frequency estimation of pre-stressed and composite floors
… have resulted in long spans and slender floors of low frequencies. These frequencies may be within the range of the first few harmonics of daily life human activities. Though the problem of resonance with walking vibrations, an activity most common on all floors, is unlikely, high …

Break-even volatility for caps, floors and swaptions
This dissertation investigates break-even volatility in the context of the South African interest rate market. Introduced by Dupire (2006), break-even volatility is a retrospective measure defined as the volatility that ensures the profit or loss from a delta hedged option position is zero. …

Fundamental Natural Frequency of Steel Joist Supported Floors
… first natural frequency of steel joist supported floors were studied. The aspects are: 1) determining which finite element model best predict the behavior of joist-slab tee-beams, 2) investigating the ability of proposed equations to calculate the effective moment of inertia of joist-slab …

Between Floors: The Ups and Downs of Mediated Narrative
“Between Floors: The Ups and Downs of Mediated Narrative” and the accompanying creative remediation project, “Between Floors: Love and Other Blood Related Diseases,” meld theory and practice of print with electronic literature and installation art. I argue that as the medium changes, the narrative …

The numerical modelling of composite floors exposed to fire
… on the behaviour of steel concrete composite floors. A theory has been developed to calculate deflections during the fire and the ultimate strength ofthe composite floor under such conditions. The solution is based on the finite difference method. It takes temperature-dependent material …

Three-dimensional modelling of heat transfer from slab floors
Earth-coupled heat transfer processes have been recognized in recent years as a potential source of significant energy savings in both conventional and earth-sheltered designs. Because of the complexity of the building/soil/atmosphere interaction, however, important aspects of earth-coupled heat …

Uncovering the premium for higher floors in office space
… do commercial office rents vary across different floors within the same building? This question seeks to understand the heterogeneity of real estate by considering the location in three dimensions. This thesis aims to answer that question by analyzing office suite listings across geographies. The …

The effects of partitions on the vibration serviceability of concrete floors
The growing demand to construct long, slender floors with minimum supports for aesthetic and economic reasons especially in modern building developments has resulted in increased floor slenderness leading to vibration problems. As a result, vibration serviceability has become the governing design …

Impact sound insulation of flooring systems with polyurethane foam on concrete floors
… twenty years and impact noise through separating floors has been identified as a particularly important problem. One accepted method for improving impact sound insulation is to use floating floors in which the walking surfaces are isolated from the supporting structure by a resilient layer. …

Accounting for roll-over risk in the pricing of caps and floors
… of this work is to price XIBOR-based caps and floors under a framework which accounts for roll-over risk. This reformulation of interest-rate derivatives is achieved using Fourier Transform methods as well as Monte Carlo simulations for comparison. We found that the results obtained using the …

From Forest Floors to Pharmacology: Elucidating Millipede Defensive Alkaloids for Drug Discovery
Millipedes are some of the oldest animals on earth, evolving over 400 million years ago (mya). The subterclass, Colobognatha evolved 99 mya and are largely understudied compared to other classes of millipedes. Like most other millipede classes, Colobognatha possess repugnatorial glands, which store …

Investigation of several aspects of the vibration characteristics of steel member-supported floors
… characteristics of steel member supported floors were investigated. The four aspects are: 1) the number of tee-beams effective in resisting a heel-drop impact for steel joist and steel beam-concrete slab floors, 2) the effective moment of inertia of steel joist and joist-girder members, 3) …
