Accelerated testing of an asphalt pavement with the third-scale model mobile load simulator (MMLS3)

Walubita, Lubinda F. (Stellenbosch : Stellenbosch University, 2000-12)

ENGLISH ABSTRACT: Accelerated pavement testing (APT) is the application of a wheel loading, to a prototype or actual layered, structural pavement system to determine pavement response and performance under controlled, ...
Algorithmic component and system reliability analysis of truss structures

Hashemolhosseini, Sepehr (Stellenbosch : Stellenbosch University, 2013-12)

ENGLISH ABSTRACT: Most of the parameters involved in the design and analysis of structures are of stochastic nature. This is, therefore, of paramount importance to be able to perform a fully stochastic analysis of structures ...
The application of Doppler velocity meters in the measurement of open channel discharges

Gunther, U. K. (Uwe Karsten) (Stellenbosch : Stellenbosch University, 2001-12)

ENGLISH ABSTRACT: This report deals with the use of Doppler meters to measure flow velocities and hence discharges in streams. The Doppler meter measures the shift in frequency of an acoustic wave, which it emits and ...
Application of neural networks in pavement management

Bredenhann S. J. (Stellenbosch : Stellenbosch University, 2000-03)

ENGLISH ABSTRACT: The intent of this thesis is to examine the solving of problems with neural networks. Three cases are investigated: the calculation of a Visual Condition Index (VCI), the determination ofthe reseal need, ...
The application of the numerical wind wave model SWAN to a selected field case on the South African coast

Van der Westhuysen, A. J. (Stellenbosch : University of Stellenbosch, 2002-03)

ENGLISH ABSTRACT: In this study the numerical short wave model SWAN is evaluated for application to a selected coastal region in South Africa. The aim of this study was to evaluate the degree of accuracy with which SWAN ...
An approach to multi-objective life cycle cost optimization of wind turbine tower structures

Horsthemke, Hagen Wolfgang (Stellenbosch : Stellenbosch University, 2013-12)

ENGLISH ABSTRACT: Support tower structures of Wind Energy Conversion Systems (WECS) are major cost items and by means of integrated design and optimization, the Life-Cycle Cost (LCC) can be reduced substantially. In this ...
Assessing management processes of labour based construction works

Nyando, Cleaverson K.C. (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Labour based technology has extensively been utilized in delivery of poverty alleviation programmes. Most of the projects implemented have been of construction in nature. In many cases, labour based ...
An Assessment of Accommodation Strategies for Coastal Adaptation in Cape Town, South Africa, in Response to Climate Change

Faasen, Petronella (Stellenbosch : Stellenbosch University, 2014-04)

ENGLISH ABSTRACT: As the world finds itself increasingly unable to avoid the negative impacts of the physical phenomena associated with climate change, adaptation to climate change has been brought to the forefront of the ...
Assessment of seismic drift of structural walls designed according to SANS 10160 - Part 4

Le Roux, Rudolf Cornelis (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Reinforced concrete structures, designed according to proper capacity design guidelines, can deform inelastically without loss of strength. Therefore, such structures need not be designed for full ...
Assessment of the behaviour factor for the seismic design of reinforced concrete structural walls according to SANS 10160 : part 4

Spathelf, Christian Alexander (Stellenbosch : Stellenbosch University, 2008-12)

The South African code for the design loading of building structures, namely SABS 0160 (1989), was revised with the requirements for seismic design prescribed in SANS 10160: Part 4: Seismic actions and general requirements ...
The behaviour of fibre reinforced concrete (SHCC) under biaxial compression and tension

Swanepoel, Willie (Stellenbosch : Stellenbosch University, 2011-12)

ENGLISH ABSTRACT: Strain hardening cement‐based composites (SHCC) are fibre‐reinforced composites designed to form multiple fine cracks under tensile and flexural load. The cracks are controlled to small widths, ...
The behaviour of strain-hardening cement composites under biaxial compression

Molapo, Katiso Tokoloho (Stellenbosch : University of Stellenbosch, 2010-12)

ENGLISH ABSTRACT: Reinforced concrete is susceptible to cracking. This makes it less durable than it would be had it been crack-free. Ingress of harmful substances into reinforced concrete through cracks – which causes ...
Bend diversion to minimise sediment intake

Brink, C.J. (Stellenbosch : University of Stellenbosch, 2004-12)

ENGLISH ABSTRACT: The primary aim of the research was to determine the optimum diversion location in a curved channel to minimise the abstraction of sediment. The secondary aim was to determine the optimum diversion angle ...
Best practice of crane support structures design : an expert survey

Thompson, Geoffrey (Stellenbosch : University of Stellenbosch, 2007-12)

Research on cranes and crane support structures has been completed at Stellenbosch University’s Structural Division. In order to link the research already completed with that which is practically relevant, an industry ...
CAD-supported preliminary column force calculations in multi-storey buildings

Lourens, Eliz-Mari (Stellenbosch : University of Stellenbosch, 2006-12)

The predominately manual, time-consuming and error-prone procedure currently used in engineering offices for the calculation of preliminary column forces in multi-storey buildings constitutes the motive for the research ...
Calculation of the forces on a moored ship due to a passing container ship

Swiegers, Pierre Brink (Stellenbosch : Stellenbosch University, 2011-12)

ENGLISH ABSTRACT: When a sailing ship passes a moored ship the moored ship experiences forces and moments. These forces and moments cause the moored ship to move. The resulting ship motions due to the passing ship can ...
The calibration of compound crump and sharp-crested gauging weirs in South Africa

Wessels, P. (Pieter) (Stellenbosch : Stellenbosch University, 1996-12)

ENGLISH ABSTRACT: The present network of now gauging stations in South Africa has grown from isolated observations on an ad extensive is to an extensive network of stations across the country. Standardised gauging ...
