Delay and queue lengths at stop/go control during half-width construction
(South African Institution of Civil Engineering, 2015-12)ENGLISH ABSTRACT: It is common practice in South Africa that road reseal projects, road reconstruction projects or road upgrade projects on two-lane, two-way roads are constructed in half-widths, resulting in a situation ... -
Development of a deterministic design model for a high-rate algal pond
(South African Water Research Commission, 2018-09-25)ENGLISH ABSTRACT: Inadequate wastewater treatment is a major problem in South Africa. Existing wastewater treatment facilities often lack sufficient skilled labour, resulting in partially treated effluent. Increasing ... -
Development of an updated fundamental basic wind speed map for SANS 10160-3
(South African Institution of Civil Engineering, 2017-11)ENGLISH ABSTRACT: This paper evaluates the need for updating the strong wind climate stipulations of South Africa for the design of structures in accordance with SANS 10160-3:2010, as based on the latest information presented ... -
Dynamic behaviour of normally reinforced concrete wind turbine support structures
(South African Institution of Civil Engineering, 2015-12)ENGLISH ABSTRACT: Transportation logistics of large steel towers have led to concrete towers becoming a viable option. There are currently no design codes dealing exclusively with the design of concrete wind turbine towers. ... -
Eccentric loading of CFDST columns
(World Academy of Science, Engineering and Technology, 2014)ENGLISH ABSTRACT: Columns have traditionally been constructed of reinforced concrete or structural steel. Much attention was allocated to estimate the axial capacity of the traditional column sections to the detriment of ... -
The effect of aeration through an internal gallery of a dam on the cavitation risk of Roberts splitters
(South African Institution of Civil Engineering, 2018)ENGLISH ABSTRACT: Roberts splitters is an effective means of energy dissipation for dam spillways. Roberts' (1943) standard unaerated splitter design procedure is, however, limited to a spillway head (H) of 3.0 m (q ~ 12 ... -
The effect of parameters on the end buffer impact force history of the crane
(South African Institution of Civil Engineering, 2012-04)ENGLISH ABSTRACT: An overarching investigation was conducted to provide engineers with guidelines for designing crane supporting structures. The focus of this study was to determine whether the identified parameters had ... -
Evaluation of locally available synthetic macro fibres in a single-fibre pullout test in concrete
(South African Institution of Civil Engineering, 2018-03)ENGLISH ABSTRACT: There is increasing use of synthetic macro fibres in concrete applications. However, the performance of these fibres varies, based on various factors. This study investigates the fibre/ matrix interface ... -
Evaluation of rock types for concrete aggregate suitability for the construction of a gravimeter vault and access road at the Matjiesfontein Geodesy Observatory site near Matjiesfontein, South Africa
(South African Institution of Civil Engineering, 2014-08)Often the use of local rock material for construction purposes is overlooked in engineering, which could reduce costs in terms of procurement and transport, as well as being more environmentally friendly by minimising the ... -
Evaluation of the standard design flood method in selected basins in South Africa
(South African Institution of Civil Engineering, 2012-10)Design flood estimations display relatively wide confidence bands of uncertainty around all estimates of flood magnitude-frequency relationships. Taking cognisance of this, and the fact that most of the available design ... -
Finite element analyses of the structural behaviour of pylons supporting an inclined coal conveyor
(South African Institution of Civil Engineering, 2015-09)ENGLISH ABSTRACT: As part of the coal conveyance system at Medupi Power Station, an inclined coal conveyor will transport coal from the stockyard to the coal transfer tower, and from there to the boilers. The conveyor is ... -
Garden irrigation as household end-use in the presence of supplementary groundwater supply
(South African Water Research Commission, 2019-05)ENGLISH ABSTRACT: Garden irrigation is a significant and variable household water end‑use, while groundwater abstraction may be a notable supplementary water source available in some serviced residential areas. Residential ... -
Hydraulic model study of the blowback behaviour of the bottom outlet of the Berg River Dam, South Africa
(South African Institution of Civil Engineering, 2016)The Berg River Dam is equipped with the first multi-level draw-off environmental flood release outlet in South Africa and can release flows up to about 200 m3/s. The outlet is controlled by a radial gate at the outlet end, ... -
Impact of discounted professional fees on the risk exposure of civil and structural engineering services consultants in South Africa
(South African Institution of Civil Engineering, 2018-03)ENGLISH ABSTRACT: The abolition of mandatory fee scales and the prevalence of lowest-cost bidding for the procurement of consulting services in South Africa have seen engineering services consultants compete based on price ... -
Injury severity in relation to seatbelt use in Cape Town, South Africa : a pilot study
(Health & Medical Publishing Group, 2014-07)Background. Injuries and deaths from road traffic collisions present an enormous challenge to the South African (SA) healthcare system. The use of restraining devices is an important preventive measure. Objective. To ... -
Interventions to promote the use of seat belts
(Cochrane, 2014-07-24)This is the protocol for a review and there is no abstract. The objectives are as follows: To assess the effects of interventions promoting the use of seat belts. -
Invasive alien plants and water resources in South Africa : current understanding, predictive ability and research challenges
(Academy of Science for South Africa, 2004)Predictions that invasive alien plants would use significant amounts of water were a major factor in the establishment of South Africa's Working for Water programme, which aims to protect water resources by clearing these ... -
Investigation into increasing short-duration rainfall intensities in South Africa
(Water Research Commission, 2015-04)Extreme storms in South Africa and specifically in the Western Cape have been responsible for widespread destruction to property and infrastructure, even leading to displacement and death. The occurrences of these storms ... -
An investigation into the evidence of seasonal rainfall pattern shifts in the Western Cape, South Africa
(South African Institution of Civil Engineering, 2017-12)ENGLISH ABSTRACT: Climate change is a highly contentious topic in the modern world. There is much evidence to indicate that climatic shifts and extreme weather anomalies are taking place globally, in some places more ... -
The management of constructability knowledge in the building industry through lessons learnt programme
(South African Institution of Civil Engineering, 2014-04)In the 1980s the term "constructability" evolved in the USA. The proponents of this concept believe that constructability, which embraces both design and management functions, is comprehensive in facilitating construction ...
