State of the art of steel–concrete composite structures in Brazil

Abstract

Steel-concrete composite structures are now increasingly used in Brazil and are the subject of significant research by the country's leading universities. This paper summarises the typology, state of the art and usage of steelcomposite structures from a Brazilian perspective. It presents the concepts, definitions and design philosophy for basic structural elements, including composite slabs, beams and columns, and also for various types of connections.Summaries of the extensive research findings are presented for each composite element. The paper concludes with a call for all the research results to be condensed into a single design manual, which in turn will help Brazil's fastgrowing construction industry take full advantage of the benefits of composite construction techniques.

Ultimate strength prediction of steel–concrete composite cellular beams with PCHCS

“…These elements are produced in specific environments with monitoring and strict technological control. The use of PCHCS offers advantages such as the possibility of overcoming large spans, speed, and reduced construction costs [2][3][4]. One of the common uses of PCHCS is in flooring systems.…”

Factors affecting the market development of steel construction

“…(Owens and Wood, 1998;Dowling et al, 2001). A significant reduction of using steel was observed during the economic recession in Brazil in the 1980s, while steel became common from the 1990s during which national economic stability achieved (De Nardin and Debs, 2013 The rapid growth of steel construction was beneficial from the growing economy in many marketplaces such as the UK (Moore and Tordoff, 2007) and Japan (Kanno et al, 2012). Urbanization and demographic changes can support the growth of steel-intensive construction projects because of the increasing demand for public areas, playground facilities and other urban furniture, reflecting the rapid economic growths in many developing countries.…”

“…The significance of continuous development of design codes, standards and specifications in the steel construction industry is remarkably similar around the world. The contribution of Eurocodes and ASTM to the success of the constructional steel market was notable in the UK and USA (Moore and Tordoff, 2007;Bjorhovde, 2004), while the lack of compatible design standards hindered the market in Brazil (De Nardin and Debs, 2013). The development of design codes, standards and specifications has been recognized as a key role in enabling the wider application of structural steel in construction (Baddoo, 2008;Owens, 2000).…”

Steel-Concrete Composite Beams with Precast Hollow-Core Slabs: A Sustainable Solution

“…In Albero et al [9], the estimate of the number of PCHCS floors installed in Europe was estimated to be close to 1 billion square meters. The use of PCHCSs offers advantages; e.g., large spans, speed of construction, and reduced construction costs [5,[10][11][12][13][14]. In the European Union, according to Ahmed and Tsavdaridis [15], construction and building are responsible for about 40% of environmental impact.…”
