Skorpen, Sarah Anne; Dekker, N.W. (South African Institution of Civil Engineering, 2014-04)Finite Element methods have been used by civil and structural engineers since the 1960s, and the theory behind this is well researched. However, there is still a lack of direction on how to use the information obtained ...

Burdzik, W.M.G.; Skorpen, Sarah Anne; Jansen van Rensburg, Karin (Institution of Civil Engineering, 2014-03)Recent roof failures in South Africa, of multiple ply nail plated trusses, have necessitated a rethink about the way in which timber trusses are analysed. The authors believe that the relative slip between plies caused by ...

Burdzik, W.M.G.; Skorpen, Sarah Anne (South African Institution of Civil Engineering, 2016-12)Most of the current research on the design of timber composite beams involves either complex mathematical models which are not checked with experimental testing, or is purely based on experimental work with no attempt ...

Measured temperature effects during the construction of a prestressed precast concrete bridge beam Kusel, Frank; Kearsley, Elsabe P.; Butler, Liam J.; Skorpen, Sarah Anne; Elshafie, M.Z.E.B. (EDP Sciences, 2018-10)Prestress losses in precast concrete beams include the short-term effects of elastic shortening and the long-term effects of concrete shrinkage, concrete creep and steel relaxation. Temperature effects are, however, excluded. ...

Burdzik, W.M.G.; Skorpen, Sarah Anne (Elsevier, 2014-09)Diagonal bracing is a common method used in South Africa for the bracing of timber trussed roofs with spans of less than 9 m. In the typical diagonally braced roof system, the brace is placed on the underside of the ...

Venter, Simon Herman; Skorpen, Sarah Anne; Janse van Rensburg, Ben W. (South African Institution of Civil Engineering, 2019-12)The current South African Steel design code, SANS 10162-1, has a set of effective length factors for overhang beams which is independent of the geometrical properties of the beam and the lengths of the backspan and ...

Towards predicting the buckling and crushing strength of graded SA pine with high slenderness ratios Burdzik, W.M.G.; Skorpen, Sarah Anne (South African Institution of Civil Engineering, 2020-03)There is an apparent increase in failure of timber truss web members or compression chords. This paper seeks to reassess buckling of the compression chords with specific focus on web members. There are two possibilities ...
