Abstract: This paper presents analytical and experimental results on ductility of reinforced lightweight concrete beams and columns in the form of moment curvature relationships, and compares the response with that of normal reinforced concrete members. The experimental part is limited to flexural tests on beams made of lightweight concrete. The latter is obtained with natural lightweight aggregates. Concrete and steel stress-strain models in compression and tension are integrated analytically through the section in ord… Show more

“…Nevertheless, at failure, it was observed that the reinforced OPS concrete beams exhibited twice the deflection compared to that for NWC beams. The enhanced ductility of reinforced LWC beam made using lightweight scoria aggregates was also observed by Charif et al [18]. When analysing the crack behaviour of the reinforced concrete beams, the authors reported that the crack widths of the reinforced OPS concrete beams were smaller compared to that for reinforced NWC beams.…”

“…There are many methods of numerical integration computing area integrals (1) such as those described by Sfakianakis (2009), Bonet et al (2006, Batistuta et al (2007), and Charalampakis et al (2008). Area integrals can be transformed to border integrals using Green's theorem with appropriate numerical techniques as reported by Fafitis (2001), Zupan and Saje (2005), and Charif et al (2014). Analytical integration is only possible with some particular models and with any polynomial form.…”

“…Analytical integration is only possible with some particular models and with any polynomial form. This efficient method is used here and is described in details by Charif et al (2014). Integral relations (1) can be expressed with respect to neutral axis coordinates (   , ), as shown in Figure 5.…”

“…In this respect, Bureau of Indian Standard (BIS) exquisitely does the capacity of categorizing three separate grades of OPC, for example, 33, 43, and 53, which have chronically been widely utilized in construction industry [3]. The strength, sturdiness, and different attributes of concrete rely on the properties of its ingredients, the proportion of the mix, the strategy of compaction, and different controls amid placing, compaction, and curing [4]. Concrete containing wastes can help construction manageable quality and contribute to the advancement of the civil engineering region by employing industrial waste, minimizing the utilization of natural assets, and producing more effective materials [5].…”
