Factors affecting the productivity of building craftsmen—studies of Uganda

Factors affecting the productivity of building craftsmen—studies of Uganda Henry Mwanaki Alinaitwe Abstract. Poor productivity of construction workers is one of the causes of cost and time overruns in construction projects. The productivity of labour is particularly important especially in developing countries, where most of the building construction work is still on manual basis. This […]

Application of computer simulation to construction of incremental launching bridges

Application of computer simulation to construction of incremental launching bridges Mohamed Marzouk Abstract. Construction of bridges is associated with uncertainties that rise due to unavailability of resources, equipment breakdown and/or working environment. Bridge construction techniques can be grouped into six main categories: 1) cast-in-situ on false work, 2) cantilever carriage, 3) stepping formwork, 4) launching […]

Mathematical-neural model for assessing productivity of earthmoving machinery

Mathematical-neural model for assessing productivity of earthmoving machinery Krzysztof Schabowicz Abstract. Many construction processes are carried out by machines working together and forming technological systems, eg earthmoving machinery made up of excavators and haulers (trucks). Productivity ([W.sub.(N)]) is a key to valuate the process design purposes. The paper presents the results obtained by applying artificial […]

Elastic-plastic fracture analysis of structural columns

Elastic-plastic fracture analysis of structural columns Abdesselam Zergua Abstract. This research is achieved in the general frame-work of the study of the concrete behaviour. It has for objective the development of a numerical tool able to predict the behaviour of reinforced concrete columns with circular and square cross-sections under an increasing compressive axial load. The […]

Behaviour of hollow concrete-filled steel tubular composite elements

Behaviour of hollow concrete-filled steel tubular composite elements Artiomas Kuranovas Abstract. Behaviour of composite steel-concrete elements in various loading stages is quite well analysed by theoretical investigations and experiments. Concrete-Filled Steel Tube (CFST) is one of many composite elements used at present in civil engineering. Different approaches and design philosophies were adopted in different design […]

a case study for Slovenia

Environmental management systems and construction SMES: a case study for Slovenia Jana Selih Abstract. Construction projects and activities are, in general, associated with a wide range of environmental impacts. Therefore the principles of sustainable development should be adopted during construction just like in any other industrial sector. At the organisation’s level, one of the ways […]
