“…The ultimate load of RACFST decreased with increasing RCA replacement ratio. Also, Yang and Han [21] reported the similar research work and results. Therefore, it could be concluded that RACFST column has slightly lower but comparable load capacity compared with conventional CFT column.…”

This work proposes two aspects about construction materials abased on Wenchuan post-earthquake investigations. According to different feature failure modes in various damaged structures and the cause of the damage to the effects of the loading during the ground motion, the structural failures were found related to low cycle fatigue (LCF) properties of building steel. The hitherto research development is presented briefly. The characters of cycle response of the steels are tested and discussed. During the post-earthquake reconstruction process, the disposal of huge quantities of earthquake demolition waste brought great challenges. Utilizing the waste concrete taken from earthquake-stricken area as recycled coarse aggregate (RCA) in the new concrete is conducted. Furthermore, the application perspective of RCA is discussed.

“…Their results show a similar bearing capacity for the members and also that any differences in load-bearing capacity can be disregarded in practice. The properties of RACFST long columns have been reported by Mohanraj et al (2011), Zhang et al (2013) and Yang and Han (2006b). The experimental results indicate that a RACFST long column under eccentric compression loading has similar loading and deformation capacities compared to normal CFST columns.…”

“…It indicates that the influence of replacement ratio on the bearing capacity of RACFST long columns vary with the eccentricity ratio. Yang and Han (2006b) found that the ultimate loading capacities of RACFST columns decrease with an increase of loading eccentricity ratio. The loading capacities of circular RACFST columns with NC range from 1.7 to 9.1% higher than those of circular columns with RAC containing 25% and 50% RCA, respectively.…”

A series of investigations on structural behaviour, durability, fire-resistance and seismic performance of composite members with recycled aggregate concrete (RAC) have been carried out in the past 10 years (2005–2014). This paper is consisted of three parts: the first part introduces and discusses the research progress in regard to the structural behaviour of RAC filled steel tubular columns and beams; the second part concentrates on the structural behaviour of steel-reinforced RAC members, including columns, beams, shear walls and slabs; and the third part focuses on the long-term performance of composite members with RAC, involving fire resistance, durability and seismic performance. It seems that RAC composite members with different replacement ratios of recycled coarse aggregate have slightly lower or similar structural behaviour compared to that of normal concrete composite members. Review results reveal that it is feasible to apply steel-RAC composite members as structural applications. This intensive review provides a reasonable knowledge of the structural behaviour of steel-RAC composite members, and recommends further investigations on the failure mechanics and durability of steel-RAC composite members which are needed to promote safe and economic application in the future.

“…Stiffness, strength, ductility, seismic and fire resistance, deformation characteristics, elimination of formwork costs, installation, economy, and good performance are among the advantages achieved in using such a structural system. Accordingly, a great deal of experimental research works has been done by Zeghiche and Chaoui (2005), Ellobody et al (2006), Yang and Han (2006), Guo et al (2007), Lai and Ho (2014), Feng et al (2015), and Wang et al (2015) among many others, to investigate the behaviour of CFST columns. Alternatively, much numerical research work has been reported by Shams and Saadeghvaziri (1999), Hu et al (2003), Valipour and Foster (2010), Liang (2011), Tao et al (2013), Wang and Young (2013), Patel et al (2014), Zhang et al (2015), Aslani et al (2015), and analytical studies by Choi and Xiao (2010), Schneider (1998), Brauns (1999, Susantha et al (2001), Fam et al (2004), Kuranovas et al (2009).…”

This paper presents an exact model for studying the global buckling of concrete-filled steel tubular (CFST) columns with compliant interfaces between the concrete core and steel tube. This model is then used to evaluate exact critical buckling loads and modes of CFST columns. The results prove that interface compliance can considerably reduce the critical buckling loads of CFST columns. A good agreement between analytical and experimental buckling loads is obtained if at least one among longitudinal and radial interfacial stiffnesses is high. The parametric study reveals that buckling loads of CFST columns are very much affected by the interfacial stiffness and boundary conditions.
