    • The numerical simulation of wheel loads on an electric overhead travelling crane 

      McKenzie, Kim Anne (Stellenbosch: University of Stellenbosch, 2007-12)
      The failure rate of electric overhead travelling crane supporting structures across the world is unacceptably high. Failures occur even when the supporting structures are designed within the relevant design codes. This ...

    • Object – oriented Steel Member Design Framework 

      Hewetson, C.G. (Stellenbosch : University of Stellenbosch, 2005-12)
      Adequate member design is a vital part of structural design. Current design software automates the design process by making use of the finite element model to create a design model. Although this is time effective, the ...

    • Object-oriented finite element framework 

      Olivier, Albertus Hendrik (Stellenbosch : Stellenbosch University, 2002-12)
      ENGLISH ABSTRACT: The role of the computer has changed from a calculation tool to a tool that supports human thinking. In this thesis fundamental aspects of the Finite Element method are mapped to an object model with ...

    • Object-oriented steel connection design framework 

      Willemse, G. E. (Grant Erin) (Stellenbosch : Stellenbosch University, 2004-12)
      ENGLISH ABSTRACT: Connections are a vitally important part of any structural framework. Thisstatement may seem obvious, yet it is surprisinghow often insufficient attention is given to the design of this essential aspect ...

    • The occurrence and extent of collapse settlement in residual granite in the Stellenbosch area 

      Gildenhuys, Nanine (Stellenbosch : University of Stellenbosch, 2010-12)
      ENGLISH ABSTRACT: Large areas of the earth’s surface are covered by soils that are susceptible to large decreases in bulk volume when they become saturated. These soils are termed collapsing soils and are very common in ...

    • Oorsake van padongelukke met verwysing na die R44 tussen Somerset-Wes en Klapmuts 

      Vogel, Liesel (Stellenbosch : Stellenbosch University, 2004-12)
      ENGLISH ABSTRACT: South Africa, and other developing countries, experience great problems concerning road traffic accidents. Despite road safety campaigns like Arrive Alive being launched, accident rates do not decline ...

    • An optimisation strategy for small airports 

      De Vos, Johan (Stellenbosch : University of Stellenbosch, 2010-03)
      ENGLISH ABSTRACT: The aviation industry is an extremely dynamic industry where all stakeholders need to ensure that the operational margins are clearly identified and adhered to. Failure to actively and continuously ...

    • Options to reduce sediment build-up in a surf zone trench protected by an open-ended cofferdam 

      Muller, Jacobus Johannes (Stellenbosch : Stellenbosch University, 2015-03)
      ENGLISH ABSTRACT: When constructing a submarine pipeline, construction teams must work in the hostile environment in the ocean known as the surf zone. The surf zone is the area along a shoreline stretching between the ...
