  • Applications of response sensitivity analysis in earthquake engineering 
    Roth, C.P. (Chris); Grigoriu, Mircea D. (South African Institution of Civil Engineering, 2010-10)
    Response sensitivity analysis as a part of dynamic finite element structural analysis has many applications to structures of realistic scale and complexity in earthquake engineering. A demonstration project, consisting of ...
  • Development of a remaining useful life (RUL) model for reinforced concrete beams subjected to high-cycle fatigue 
    Wannenburg, Willem; Inglis, Helen Mary; Wannenburg, Johann; Roth, C.P. (Chris) (Emerald, 2022-06)
    PURPOSE : Failure of a critical reinforced concrete beam due to fatigue can have severe safety and production consequences, and preventative repair/replacement of such a beam is expensive. It would therefore be beneficial ...
  • Field measurement and dynamic analysis of a steel truss railway bridge 
    Shibeshi, Rahel; Roth, C.P. (Chris) (South African Institution of Civil Engineering, 2016-09)
    In this study a dynamic analysis of a 77-year-old single-span steel truss railway bridge was carried out. The study was approached by three different methods – field measurement, modal analysis using a three-dimensional ...
  • Updated provisions of SANS 10160-4 for steel structures 
    Roth, C.P. (Chris); Gebremeskel, A. (South African Institution of Civil Engineering, 2017-03)
    A forthcoming revision of SANS 10160-4 (Seismic actions and general requirements for buildings) addresses the omission of structural steel design provisions from the standard, as well as contradictions between SANS 10160 ...
