Precast lightweight foamed concrete walling, a structural system for low-rise residential buildings
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Lightweight foamed concrete, in contrast to normal weight concrete, is a low density, zero coarse aggregate concrete. The applications of foamed concrete have previously been non-structural and made use ... -
Optimisation of wind turbine foundations
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: This study seeks to optimize the foundations of tall wind turbine support structures in South Africa. It is postulated that the concrete quantity can be reduced in gravity based foundations by incorporating ... -
An investigation into the structural behaviour of a novel cellular beam structure in fire
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: The Southern African Institute of Steel Construction (SAISC) has developed a novel cellular beam structure (CBS), which has been specifically designed for the construction of two to ten storey office ... -
An independent review and summary of geotechnical information pertaining to the sidewall stability of the Kimberley "Big Hole" mine, with specific focus on the weathering and deterioration of the Kimberley shales.
(Stellenbosch : Stellenbosch University, 2017-12)The Kimberley “Big Hole” Mine in the center of Kimberley experiences frequent small scale toppling and landslide slope failure events, which causes the sidewalls of the pit to slowly migrate outward towards surrounding ... -
Great Brak Island - measures for flood defence
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: This thesis firstly presents the analysis of large flood events, causing low-lying property in and around the Great Brak estuary to be inundated. The nature of several South African estuaries renders ... -
Effect of the form of the overhang of a recurve seawall to reduce wave overtopping
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Coastal areas around the world are experiencing a rise in sea level due to the effects of global warming. As a large percentage of the world’s population resides within the coastal zone, the rise in sea ... -
Design method development and software implementation for fibre-reinforced concrete slabs-on-ground
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Ground-supported concrete slabs are common structural elements, used for a multitude of purposes. In industrial flooring applications, slabs-on-ground (SOG) are often subjected to severe loads, concentrated ... -
A decision model for the investment in technology to reduce concrete rework
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: This study investigated a method to choose technology that reduces the rework of structural concrete works which results in poor quality during construction. The technology considered is identified as ... -
Corrosion propagation in cracked reinforced concrete structures
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: The durability of a reinforced concrete (RC) structure is significantly influenced by the presence of cracks. Cracks act as pathways that accelerate the ingress of corrosion agents into the concrete to ... -
A cooperative venture capital framework : an innovation pipeline developed with an enterprise engineering approach that supports and promotes entrepreneurial teams in commercialising intellectual property and technology
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: The field of entrepreneurship and innovation has been prominent in the past century, with increasingly more research produced in recent decades. The identified interdependencies between entrepreneurship ... -
A comparison of structural optimization techniques with extension towards multi-objective problems
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Structural optimization is becoming an integral part of the modern structural design process in the search to yield more economical structures. The optimization of structures is typically performed with ... -
Comparison of stochastic streamflow generators and the use thereof within the water resources yield model and MIKE Hydro Basin
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: The development and improvement of hydrological simulation software models is a continuous process. These software models, together with hydrological stochastic data generators enhances the ability to ... -
Carbonation induced corrosion in integral and non-integral surface treated lightweight foam concrete
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Carbonation induced corrosion is a concern in reinforced lightweight foam concrete (R/LWFC) as a result of air entrainment. Concerns arise from whether the air voids increase diffusivity of carbon dioxide ... -
Berm height at temporarily open/closed estuaries in South Africa: analysis and predictive methods
(2017-12)ENGLISH ABSTRACT: This study investigates the berm crest elevation at South African Temporarily Open/Closed Estuaries (TOCE), as well as the processes involved in berm growth, and the drivers that contribute to variation ... -
Artificial aeration on stepped spillways with piers and flares to mitigate cavitation damage
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Stepped spillways have been used for approximately 3500 years and, with the recent technical advances in Roller Compacted Concrete construction, these spillways have received a renewed interest over the ...
