Accounting for moment-rotation behaviour of connections in portal frames
(South African Institution of Civil Engineering, 2014-04)Portal frames are steel structures used to construct industrial buildings. Conventional analysis techniques used by practising engineering professionals assume that the eave, ridge and base connections are either infinitely ... -
Alternative wall‑to‑slab connection systems in reinforced concrete structures
(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 ... -
Analysis of water use by gated communities in South Africa
(South African Water Research Commission, 2018)ENGLISH ABSTRACT: Gated communities (hereafter GCs) are popular in many countries, including South Africa, because added security and lifestyle improvements are offered relative to homes built on freestanding properties. ... -
Applying geographic information systems to delineate residential suburbs and summarise data based on individual parcel attributes
(AOSIS Publishing, 2013)Background: Information aggregation to suburb level is of interest to engineers and urban planners. Readily available suburb boundaries do not always correspond to the suburb names recorded for individual properties in ... -
Artificial aeration of stepped spillways by crest piers and flares for the mitigation of cavitation damage
(South African Institution of Civil Engineering, 2019)ENGLISH ABSTRACT: Stepped spillways are one of the oldest spillway designs dating back to 500 B.C. With technical advances in Roller Compacted Concrete (RCC) construction, the stepped spillway has become increasingly popular ... -
Assessment of the behaviour factor for the seismic design of reinforced concrete structural walls according to SANS 10160 : part 4
(South African Institution of Civil Engineering, 2012-04)Reinforced concrete structures, designed according to proper capacity design guidelines, can deform inelastically without loss of strength. Therefore, such structures need not be designed for full elastic seismic demand, ... -
Associations between stormwater retention pond parameters and pollutant (suspended solids and metals) removal efficiencies
(South African Water Research CommissionPublisher's version, 2018)ENGLISH ABSTRACT: Presented in this paper are the results of correlational analyses and logistic regression between metal substances (Cd, Cu, Pb, Zn), as well as suspended solids removal, and physical pond parameters of ... -
Baseline adjustment methodology in a shared water savings contract under serious drought conditions
(Water Research Commission, 2020-01)ENGLISH ABSTRACT: Baselines are often employed in shared water saving contracts for estimating water savings after some type of intervention by the water service company. An adjustment to the baseline may become necessary ... -
Capacity self-assessment as a catalyst for improved municipal service delivery
(South African Institution of Civil Engineering, 2015-03)ENGLISH ABSTRACT: This research paper illustrates that accurate and truthful capacity assessments are a fundamental phase of any capacity building process, and that capacity assessments play a fundamental role in reaching ... -
A case for the adoption of decentralised reinforcement learning for the control of traffic flow on South African highways
(South African Institution of Civil Engineering, 2019)ENGLISH ABSTRACT: As an alternative to capacity expansion, various dynamic highway traffic control measures have been introduced. Ramp metering and variable speed limits are often considered to be effective dynamic highway ... -
Catchment parameter analysis in flood hydrology using GIS applications
(South African Institution of Civil Engineering, 2012-10)ENGLISH ABSTRACT: The use of Geographical Information Systems (GIS) has permeated almost every field in the engineering, natural and social sciences, offering accurate, efficient, reproducible methods for collecting, ... -
A chronological review of South African guidelines for residential average annual water demand with property size as independent variable
(AOSIS OpenJournals, 2008-12)ENGLISH ABSTRACT: Guidelines for residential average annual water demand (AADD) based on property size were introduced to the South African Civil Engineering fraternity in about 1960, with the most recent publication of ... -
’n Chronologiese oorsig van Suid-Afrikaanse riglyne vir residensiële gemiddelde jaarlikse waterverbruik met erfgrootte as onafhanklike veranderlike
(AOSIS OpenJournal, 2008)ENGLISH ABSTRACT: Guidelines for residential average annual water demand (AADD) based on property size were introduced to the South African Civil Engineering fraternity in about 1960, with the most recent publication of ... -
A comparison of technical and practical aspects of Eurocode 3-1-1 and SANS 10162-1 hot-rolled steelwork design codes
(South African Institution of Civil Engineering, 2016)In South Africa engineers are starting to use the Eurocode guidelines for steelwork design, and it is important to understand the implications and differences in results that are obtained when applying the different codes. ... -
Conceptual framework for sewer pump problems allowing for fuzzy logic application
(Water Research Commission, 2015-04)Sewer pump station problems in separate sewer systems (separate from stormwater drainage systems) were investigated in order to derive a conceptual framework for decision making. Notwithstanding the fundamental service ... -
A conceptual theoretical framework to integrally assess the possible impacts of climate change on domestic irrigation water use
(South African Water Research Commission, 2015-10)Southern Africa is likely to experience higher evapotranspiration and altered rainfall characteristics due to global warming and climate change. Climate-driven water use may potentially stress water supply facilities due ... -
Consideration for design of river abstraction works in South Africa
(Water Research Commission, 2006)ENGLISH ABSTRACT: The South African climate oscillates between drought and flood. This leads to extremes in river flow and sediment transport. While storms last for minutes to days, the hydrological critical low flows can ... -
Corrosion deterioration of steel in cracked SHCC
(SpringerOpen, 2017)The presence of cracks is unavoidable in reinforced concrete structures and also a gateway for chloride into concrete, leading to corrosion of steel reinforcing bars. So, crack control, crack width limitation and chloride ... -
The creation and application of a national freight flow model for South Africa
(Scielo South Africa, 2012-04)South Africa suffered from a historical lack of freight-flow information that was detrimental to infrastructure planning, optimal network development and market structuring. This paper proposes a methodology that can fill ... -
Critical normal traffic loading for flexure of skew bridges according to TMH7
(South African Institution of Civil Engineering, 2013-10)Different types of loading due to traffic may act on bridges. The focus of this paper is on normal traffic loading according to the South African specification TMH7 (Committee of State Road Authorities 1988). TMH7 ...
