    • The seismic analysis of a typical South African unreinforced masonry structure 

      Van Der Kolf, Thomas (Stellenbosch : Stellenbosch University, 2014-04)
      ENGLISH ABSTRACT: South Africa has some regions which are susceptible to moderate seismic activity. A peak ground acceleration of between 0.1g and 0.15g can be expected in the southern parts of the Western Cape. Unreinforced ...

    • Seismic evaluation of the north bound N1-R300 bridge interchange 

      Solms, Michael Nicolas (Stellenbosch : Stellenbosch University, 2015-12)
      ENGLISH ABSTRACT: The N1 / R300 or Stellenberg interchange was designed in 1982 and construction was completed in early 1986. The bridge was designed according to the Code of procedure for the Design of Provincial Bridges ...

    • Selektering van mikroorganismes deur middel van 'n hoe substraatkonsentrasie om slykuitdying in die geaktiveerdeslykproses te herstel 

      Van der Linde, James Alwyn (Stellenbosch : University of Stellenbosch, 1983-12)
      ENGLISH ABSTRACT: The remedy of a bulking sludge was investigated by the principle of selection of microorganisms. Selection of microorganisms in activated sludge was achieved by putting a selection compartment, with a ...

    • Self-compacting concrete versus normal compacting concrete : a techno-economic analysis 

      Malherbe, Jan Stephanus (Stellenbosch : Stellenbosch University, 2015-12)
      ENGLISH ABSTRACT: Self-compacting concrete (SCC) also referred to, as self-consolidating concrete, is a relatively new concrete technology used in the construction industry. It is able to flow under its own weight and ...

    • Shear Behaviour of Engineered Cement-based Composites 

      Shang, Qinjiang (Stellenbosch : University of Stellenbosch, 2006-12)
      Some experiments utilizing the shear capacity of Engineered Cement-based Composites (ECC) have suggested that elimination of shear reinforcement is feasible when the concrete matrix is replaced by ECC. However, actual ...
