Optimality in sewer network design
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: Sewer networks form a vital part of urban infrastructure and represent a capital intensive expense in the public sector. In South Africa, a recent estimation stated that R44.75 billion is required to ... -
Nonlinear truss modelling of masonry infill frames towards sustainable residential buildings
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: With significant international efforts focused on sustainable development goals, the role of engineers in achieving sustainable infrastructure development cannot be over-emphasised. However, one of the ... -
Steel fibre-reinforced concrete: multi-scale characterisation towards numerical modelling
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: In recent years, Steel Fibre-Reinforced Concrete (SFRC) applications have increased in quantity and variety, due to its potential to partially or totally replace conventional reinforcement (rebar or welded ... -
A beam finite element for the analysis of structures in fire
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: All building structures require a specified fire resistance rating and numerous procedures have been produced for ensuring this. In engineering practice designers can generally not perform detailed ... -
Contributions to structural mechanics and durability in structural engineering
(Stellenbosch : Stellenbosch University., 2016-12)ENGLISH ABSTRACT: Contributions to structural engineering have been made since 2001 from the basis of the Department of Civil Engineering of Stellenbosch University (SU). The inauguration of the Centre for Development of ... -
Probabilistic Models of Design Wind Loads in South Africa
(Stellenbosch : Stellenbosch University, 2016-10)ENGLISH ABSTRACT: The formulation of design wind loads on structures is subject to multiple sources of uncertainties,both inherent in the physical process itself and due to the engineering models used in the formulation. ... -
Durability of Concrete under Combined Action – Mechanical Load and Alkali-Silica Reaction
(Stellenbosch : Stellenbosch University, 2016-12)ENGLISH ABSTRACT: There are still many problems remaining unresolved when concrete structures exposed to combined actions are studied separately, such as, severe environment and mechanical loads. In practice, these conditions ... -
Wind Engineering Science and its role in optimising the design of the built environment
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Wind Engineering and Building Aerodynamics constitutes a relatively recent technical science (spanning the last sixty years or so), which integrates three principal domains and the related pools of knowledge ... -
Maintenance engineering standards to fulfil the legal duty of road authorities towards safe roads
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The road network is a mode of communication that is important for the movement of people and the distribution of goods. Ownership of roads is vested in public entities. The provision of roads follows need, ... -
Management by measurement: a performance management approach for assessing ITS (Intelligent Transport Systems) projects in South Africa
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Over the past decade, the South African transport environment has actively started to adapt a technology-driven setting. Intelligent Transport Systems (ITS) applications such as Advanced Traffic Management ... -
Cracking of Plastic Concrete in Slab-Like Elements
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The cracking of plastic concrete involves two cracking types namely: plastic settlement cracking which is caused by differential settlement of the concrete and plastic shrinkage cracking which is caused ... -
Numerical modelling of performance and failure criteria for surfacing seals
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Finite element modelling of complex structures such as bituminous surfacing seals has become a viable practice to obtain insight into the structure's response behaviour. These responses are difficult, ... -
Methods for determination of coastal development setback lines in South Africa.
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: Implementation of the ICM Act (2008) has made it a legal requirement to determine coastal setback lines in all the coastal provinces of South Africa. Coastal development setback lines (or “coastal management ... -
Time-dependent Behaviour of Cracked Steel Fibre Reinforced Concrete: from Single Fibre Level to Macroscopic Level
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The addition of steel fibres to a concrete matrix is known to improve the material’s post crack mechanical behaviour under short term loading conditions. However, limited information is available on the ... -
Sediment transport dynamics in dam-break modelling
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: The prediction of breach characteristics during earth embankment dam-break modelling due to overtopping is dependent on the accurate modelling of the intrinsic breaching processes such as flow hydraulics, ... -
Design of stormwater ponds towards the reduction of metal toxins in surface waters that are utilised for South African primary food production
(Stellenbosch : Stellenbosch University, 2016-03)ENGLISH ABSTRACT: This research originated from a need for civil engineering practice to address metal pollution in stormwater runoff. Specific emphasis was placed on metals that could affect the quality of crops, livestock ... -
The Mechanical Behaviour of High-Performance Concrete with Superabsorbent Polymers (SAP)
(Stellenbosch : University of Stellenbosch, 2016-03)ENGLISH ABSTRACT: High performance concrete (HPC) is known to be of low water-binder ratio (W/B) and exhibits high strength, durability and elastic modulus amongst many other properties. HPC is susceptible to autogenous- ... -
