A contribution to the advancement of geotechnical engineering in South Africa

Day, Peter William (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: Geotechnical engineering is a relatively young field of engineering and one in which there are still many unanswered questions and gaps in our knowledge. Added to this, the geotechnical materials on ...
Hydrologic-economic appraisal of inter-basin water transfer projects

Van Niekerk, P. H. (Stellenbosch : Stellenbosch University, 2013-03)

ENGLISH ABSTRACT: South Africa‟s hydrological and geographical characteristics, coupled with the location of a large part of its mineral endowment, required the development of the complex Vaal River Supply System, including ...
Development of a wind damage and disaster risk model for South Africa

Goliger, Adam M. W. (Stellenbosch : Stellenbosch University, 2002-12)

ENGLISH ABSTRACT: This dissertation presents the development process of a wind damage and disaster management support model for South Africa. Several aspects of wind damage are analysed. The impact of wind disasters on ...
Characterisation of model uncertainty for reliability-based design of pile foundations

Dithinde, Mahongo (Stellenbosch : Stellenbosch University, 2007-12)

ENGLISH ABSTRACT: To keep pace with international trends, the introduction of geotechnical limit state design in South Africa is inevitable. To pave the way for implementation of limit state pile design in the country, ...
Video data collection method for pedestrian movement variables & development of a pedestrian spatial parameters simulation model for railway station environments

Hermant, Laurent Fernand Leon (Stellenbosch : Stellenbosch University, 2012-03-14)

ENGLISH ABSTRACT: The design of railway station environments in South Africa and to a certain extent internationally, is based on rules of thumb. These rules, using general macroscopic principles for determining peak ...
Risiko-gebaseerde besluitondersteuning in siviele ingenieurswese: 'n metodologiese benadering tot verbeterende inligtingversameling en benutting

Bester, Andre (Stellenbosch : University of Stellenbosch, 2004-12)

ENGLISH ABSTRACT:Decisions affecting construction projects are often characterised by uncertainty. One of the sources of this uncertainty is the unit costs used in detail cost estimates. Analytical techniques are available ...
Wind climatology of South Africa relevant to the design of the built environment

Kruger, Andries Coenrad (Stellenbosch : University of Stellenbosch, 2011-03)

ENGLISH ABSTRACT: In South Africa, wind constitutes the most critical environmental loading affecting the design of the built environment. The wind climatic information, which is currently incorporated in structural ...
The economic evaluation of bus and minibus taxi terminals and transfer facilities

Pienaar, Wessel Johannes (Stellenbosch : University of Stellenbosch, 1998-12)

ENGLISH ABSTRACT: The dissertation describes the functions of bus and minibus taxi terminals and transfer facilities. Planning, design and evaluation guidelines are proposed. These proposals are aimed at the following ...
Design waves for the South African coastline

Rossouw, Jan (Stellenbosch : University of Stellenbosch, 1989-03)

ENGLISH ABSTRACT: Several aspects related to the estimation and selection of design wave conditions were investigated. An analysis program which includes strict quality control routines was developed for digital Waverider ...
Towards a performance related seal design method for Bitumen and modified road seal binders

Milne, Terence Ian (Stellenbosch : University of Stellenbosch, 2004-12)

ENGLISH ABSTRACT: Bitumen based road surfacing seals and asphalt wearing courses have been used by society's Engineers "to counter the damage to the existing unsurfaced roadways by the newly developed automobile with its ...
Influence of durability properties on performance of bitumen stabilised materials

Twagira, Elias Mathaniya (Stellenbosch : University of Stellenbosch, 2010-03)

ENGLISH ABSTRACT: In both developing and developed countries, to ensure sustained economic growth the quest for optimal roads performance is an extremely high priority. A global increase in the use of foamed bitumen and ...
A methodology for radical innovation : illustrated by application to a radical civil engineering structure

Van Dyk, Cobus (Stellenbosch : Stellenbosch University, 2008-12)

Radical, far-beyond-the-norm innovation engages unknown developmental frontiers outside the familiar fields of standardised practice, requiring new and broad perspectives. This implies significant uncertainty during ...
Experimental measurement and numerical modelling of velocity, density and turbulence profiles of a gravity current

Gerber, George (Stellenbosch : Stellenbosch University, 2008-03)

The velocity, density and turbulence profiles of a horizontal, saline gravity current were measured experimentally. Stable stratfication damped the turbulence and prevented the gravity current from becoming self-similar. ...
Characterisation of material properties and behaviour of cold bituminous mixtures for road pavements

Ebels, Lucas-Jan (Stellenbosch : Stellenbosch University, 2008-03)

The cold bituminous mixtures, which are the subject of this study, are obtained by mixing mineral aggregate with either bitumen emulsion or foamed bitumen at ambient temperatures. These techniques are frequently used in ...
Supporting consistency in linked specialized engineering models through bindings and updating.

Olivier, A. H. (Stellenbosch : University of Stellenbosch, 2007-12)

Elements of the Architecture-Engineering-Construction (AEC) industry are the result of a process involving planning, engineering and construction. A number of professions and professionals are involved, and the process ...
Numerical (FEA) evaluation of crane end buffer impact forces

Haas, Trevor Neville (Stellenbosch : University of Stellenbosch, 2007-12)

The current codes of practice for the design of structures which were studied during this investigation do not explicitly account for the flexibilities and interactions of the Electric Overhead Travelling Crane (EOHTC) ...
Mathematical Modelling of Water Soil Erosion and Sediment Yield in Large Catchments

Ma, Ning (Stellenbosch : University of Stellenbosch, 2006-12)

In many part of the world, but especially in Africa, land degradation leads to severe soil erosion and high sediment yields. Mathematical models and empirical methods can be used to simulate the sediment yields. In many ...
A relation-based approach to Engineering Management Systems

Strasheim, Jacobus Alexander van Breda (Stellenbosch : University of Stellenbosch, 2007-03)

The primary goal of this thesis is to indicate how systems theory and engineering process modelling can be applied to provide models for consulting engineering service business enterprises. The typical management systems ...
Time-dependant behaviour of engineered cement-based composites

Boshoff, William Peter (Stellenbosch : University of Stellenbosch, 2007-03)

ECC (Engineered Cement-based Composites) is a type of HPC (High Performance Concrete) that was engineered to overcome the weaknesses of ordinary concrete. It shows high ductility as it can resist the full tensile load ...
Reliability based codification for the design of overhead travelling crane support structures

Dymond, Juliet Sheryl (Stellenbosch : University of Stellenbosch, 2005-12)

Electric overhead travelling bridge cranes are an integral part of many industrial processes, where they are used for moving loads around the industrial area
