The tensile properties of early age concrete and the experimental apparatus required for its determination
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: The early age cracking of concrete, which includes plastic shrinkage cracking (PShC) and plastic settlement cracking (PSeC), commonly occurs in flat concrete elements such as bridge decks and slabs or at ... -
A stochastic model for sewer base flows using Monte Carlo simulation
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: This thesis deals with understanding and quantifying the components that make up sewage base flows (SBF). SBF is a steady flow that is ubiquitous in sewers, and is clearly seen when measuring the flow ... -
Shrinkage and flexibilty behaviour of Bitumen Stabilised Materials
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: The increasing awareness of climate change causes a growing interest in pavement rehabilitation. Pavement rehabilitation by in-situ stabilisation with bitumen reduces the extraction of natural aggregate ... -
Scale model validation of QUAYSIM and WAVESCAT numerical models of ship motions
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Various numerical modelling software packages are available for predicting moored ship motions and forces. The focus of this study was to validate the numerical models QUAYSIM and WAVESCAT and how these ... -
The response of other drivers to mini-bus taxi drivers' on-road aggressive behaviour : a case study in Cape Town, South Africa
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Every year, more than 1.24 million traffic related deaths are registered globally with the highest fatality rates in middle- and low income countries. Minibus taxis represent the most dominant mode of ... -
A re-assessment of wave run up formulae
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Over the last few decades, wave run up prediction has gained the interest of numerous researchers and every newly-published paper has aimed to predict wave run up with greater accuracy. Wave run up ... -
Quantifying the sustainability of the built environment : the development of a complete environmental life cycle assessment tool
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Sustainability is becoming an increasingly important aspect in all facets of engineering. It is in particular an important consideration in the structural engineering industry, due to the prominence of ... -
Quantification of transport demand of hybrid lighter than air in Rwanda through stated preference methods
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Today, development of innovative modes of transport is taking place in order to accelerate the economic growth of transport users as well as reducing the environmental pollution, through an improved transport ... -
Pre-signal study at an at-grade intersection with separate right-turn phase
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Capacity waste happens when right-turn vehicles have right-of-way during a separate right-turn phase and lanes (e.g., through lanes) of the same approach of the intersection cannot discharge vehicles ... -
Options to reduce sediment build-up in a surf zone trench protected by an open-ended cofferdam
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: When constructing a submarine pipeline, construction teams must work in the hostile environment in the ocean known as the surf zone. The surf zone is the area along a shoreline stretching between the ... -
A non-intrusive video tracking method to measure movement of a moored vessel
(Stellenbosch : Stellenbosch UniversityStellenbosch University, 2015-03)ENGLISH ABSTRACT: There are several ports around the world currently experiencing problems with moored vessel motions. Extreme vessel motions are mainly caused by long waves, which can become trapped inside a harbour ... -
Modified simplification of HDM-4 methodology for the calculation of vehicle operating cost to incorporate terrain and expanded to all vehicle types for use in the Western Cape context F HDM-4 METHODOLOGY FOR THE CALCULATION OF VEHICLE OPERATING COST TO INCORPORATE TERRAIN AND EXPANDED TO ALL VEHICLE TYPES FOR USE IN THE WESTERN CAPE CONTEXT
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: INTRODUCTION The Western Cape Government (WCG) uses Vehicle Operating Cost (VOC) as part of their Road Management System since 1992. VOC is used in the process of prioritisation of maintenance projects ... -
A method for prioritisation of concrete bridge inspections in South Africa
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Bridges are amongst the most important structures of any highway network. Once the bridge construction is complete and a bridge is put into service, it is subjected to deteriorations. An effective condition ... -
An investigation to introduce BIM in undergraduate civil engineering teaching to improve construction processes
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: The popularity of Building Information Modelling (BIM) has grown rapidly within the construction industry, motivated by its potential advantages for improving construction processes. A majority of the ... -
An investigation of the interlayer adhesion strength between the granular base and lightly cemented subbase and its influence on the pavement performance
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Long term performance of a road pavement structure is significantly influenced by its potential to distribute traffic loading from the surface to the natural subgrade. The interlayer adhesion conditions ... -
An investigation into the axial capacity of eccentrically loaded concrete filled double skin tube columns
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: Concrete filled double skin tube (CFDST) columns is a new method of column construction. CFDST columns consists of two steel hollow sections, one inside the other, concentrically aligned. The cross-sections ... -
Interrelationship of the fluvial morphology and the salinity of the Great Fish River Estuary
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: The investigation of the interrelationship of the fluvial morphology and the salinity of the Great Fish River Estuary was performed by the combination of a two-dimensional morphological model and a one ... -
Influence of specimen geometry and grading curve on the performance of an unbound granular material
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: This research study investigates the influence of specimen geometry and grading curve, on the performance of a typical South African unbound granular material. The experimental design incorporates three ... -
Inflatable weir hydraulics
(Stellenbosch : Stellenbosch University, 2015-03)ENGLISH ABSTRACT: General objective of the study This thesis aims to evaluate the hydraulics of an inflatable weir in its fully inflated position to the almost fully deflated position using different diameter circular ... -
