      Increased water demand coupled with limited resources has increased the need for greater control over our water resources. The Orange-Fish-Sundays Transfer Scheme, which transfers 700 million m3/yr (as measured from 2002 ...

    • The realisation of the solar chimney inlet guide vanes 

      Van Dyk, Cobus (Stellenbosch : Stellenbosch University, 2004-04)
      ENGLISH ABSTRACT: Up to this point in time research on the South African solar chimney, proposed for a site in the Northern Cape, comprised of determining the structural integrity of the chimney structure, as well as ...

    • Reduction of seawall overtopping at the Strand 

      Roux, George Bishop (Stellenbosch : Stellenbosch University, 2013-03)
      ENGLISH ABSTRACT: The Strand is located within False Bay and frequently encounters large quantities of wave overtopping over the coastal defences. This results in the damage of property and infrastructure and causes streets ...

    • A relation-based approach to Engineering Management Systems 

      Strasheim, Jacobus Alexander van Breda (Stellenbosch : University of Stellenbosch, 2007-03)
      The primary goal of this thesis is to indicate how systems theory and engineering process modelling can be applied to provide models for consulting engineering service business enterprises. The typical management systems ...

    • Reliability assessment of a prestressed concrete member 

      Brand, W. W. (Willem Wouter) (Stellenbosch : Stellenbosch University, 2001-12)
      ENGLISH ABSTRACT: First-order second-moment structural reliability methods are used to assess the reliability of a prestressed concrete beam. This beam was designed for imposed office floor loads and partitions following ...

    • Reliability assessment of structural concrete with special reference to shear resistance 

      Mensah, Kenneth Kwesi (Stellenbosch : Stellenbosch University, 2012-03)
      ENGLISH ABSTRACT: Structural design standards based on the principles of structural reliability are gaining worldwide acceptance and are fast becoming the new basis of structural safety verification. The application of ...

      Mensah, Kenneth Kwesi (Stellenbosch : Stellenbosch University, 2015-03)
      ENGLISH ABSTRACT: Structural design standards based on the principles of structural reliability are gaining worldwide acceptance and are fast becoming the new basis for structural safety verification. The application of ...

    • Reliability based codification for the design of overhead travelling crane support structures 

      Dymond, Juliet Sheryl (Stellenbosch : University of Stellenbosch, 2005-12)
      Electric overhead travelling bridge cranes are an integral part of many industrial processes, where they are used for moving loads around the industrial area

    • The reliability based design of composite beams for the fire limit state 

      Van der Klashorst, Etienne (Stellenbosch: University of Stellenbosch, 2007-03)
      In the past use was made of prescriptive design rules to provide for the fire limit state. Modern Design Codes provide the scope and the means to design for fire in a performance based manner. The Eurocode provides ...

    • Reliability based optimization of concrete structural components 

      Smit, Charl Francois (Stellenbosch : Stellenbosch University, 2014-04)
