Ski-jump energy dissipation : design of a ski-jump to maximise energy dissipation and aeration.
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: One of the most effective and economical methods for the dissipation of hydraulic energy from flood waters is to project the flows into a free trajectory jet form to a location where the impact creates a ... -
Simulating domestic hot water demand by means of a stochastic end-use model
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The heating of domestic hot water (DHW) requires a substantial component of the energy demand in the residential sector, yet limited DHW demand information is available. An improved understanding of DHW ... -
Risk assessment for the importation of Bitumen for road construction into South Africa
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The purpose of this research project was to identify, assess and model the risks associated with the importation of bitumen into South Africa. Bitumen has firmly established itself as a product which is ... -
The Reliability Margin of the Direct Strength Method Prediction Model for Cold-Formed Steel Members
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: SANS 10162-2, the South African standard for structural purpose cold-formed steel, allows for design of members to resist loading of compression, bending and combinations of these among others. The focus ... -
Physical Modelling Investigation of Rock Scour Extent Due to a Plunging Jet for Typical High Head Dams
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Hydraulic structures can release high-velocity plunging jets, which can result in scouring of the rock downstream of the structure. The extent of the scour hole must be predicted and analysed to ensure ... -
The performance of locally produced supplementary cementitious materials when incorporated in concrete
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The production of cement has a strenuous impact on the environment. Nonetheless, it is required by the construction industry as a key parameter for socio-economic development. Supplementary cementitious ... -
A model for temperature control in concrete dams
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Temperature control measures need to be implemented during the construction of concrete dams in order to avoid thermal cracking. Currently, only fragmented guidance is available to the engineer who wants ... -
Investigation into the Effect of Fibre Geometry on the Performance of Macro Synthetic Fibre Reinforced Concrete
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Unreinforced concrete has the inherent shortcomings of low tensile strength and low strain capacity at fracture (ACI Committee 544, 2002). In order to overcome these shortcomings, fibres can be added to ... -
Influence of admixtures on the plastic shrinkage cracking of concrete
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Plastic shrinkage cracking (PSC) is a well-known form of cracking in concrete at early ages and causes major concerns with regard to durability and aesthetical appearance of concrete structures. PSC is ... -
The identification and modelling of rockfalls for protection measures in the Western Cape
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Natural slopes and man-made cuttings in weathered, highly jointed or fractured rock with unfavourable bedding planes can result in the release of rock blocks either from above these slopes and cuttings ... -
Fire spreading in South African low-cost settlements "A physics-based model"
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: risk of fire is increasing due to urbanization, industrialization and development of cities with dense buildings. Since low cost settlements are poorly serviced and are densely built urban areas with poor ... -
Evaluation of minimum pressure head during peak flow as design criterion for water distribution systems
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: One of the factors that drives infrastructure cost for water distribution systems (WDS), whether it being the cost of newly designed systems or the cost for maintaining and upgrading existing systems, ... -
End-of-trip facilities for cyclist and realignment of current South African bicycle legislation
(Stellenbosch : Stellrnbosch University, 2016-03)ENGLISH ABSTRACT: In this thesis, the need to provide more End-of-Trip Facilities (EOTF) for cyclists (and/or other Non-Motorised Transport (NMT) users) is highlighted. Almost all Government sectors (national, provincial ... -
Empirical study of heavy vehicle operating speeds on mountainous downgrades in the Western Cape, South Africa
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Heavy vehicles play a major role in the economic well-being of a country through its significant role in moving freight. Therefore any adverse effect to the road freight, from being stuck in traffic to ... -
The Effect of Variation Orders on Project Cost and Schedule Overruns
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Cost and schedule overruns are common occurrences in construction projects, regardless of the various studies that have been done on the subjects. These overruns can occur for a wide variety of reasons; ... -
The economic evaluation of a bicycle-sharing scheme for school and university destined commuter traffic in Stellenbosch, South Africa that is proposed as a sustainable mode of transport to relieve traffic congestion: A case study for the R44 inbound traffic from Somerset West
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The traffic congestion problem in the university town of Stellenbosch, South Africa is felt by a prodigious share of its residents and commuters on a daily basis. A quantification of the status quo verified ... -
Development and application of a multi-period pipe replacement model utilising risk-based prioritisation for water distribution systems
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The decision on whether to replace a pipe, with specific reference to a water distribution network, can be complicated by several aspects in the decision making process, such as available funding and ... -
Comparative shrinkage properties of pavement materials including recycled concrete aggregates with and without cement stabilisation
