• Sewer network design : heuristic algorithm for hydraulic optimisation 

      De Villiers, N.; Van Rooyen, G. C.; Middendorf, M. (South African Institution of Civil Engineering, 2017-09)
      ENGLISH ABSTRACT: For a given sewer network layout and choice of pipe material, the total installed cost of the network is determined mainly by the pipe diameters and slopes. Hydraulic design optimisation is the task of ...
    • Alternative wall‑to‑slab connection systems in reinforced concrete structures 

      Gerber, Johann; Van Zijl, Gideon (South African Institution of Civil Engineering, 2017-09)
      ENGLISH ABSTRACT: In many reinforced concrete structures the walls precede the construction of the connecting floors. A system is, therefore, required to connect the floors to the already cast walls. There are many different ...
