Simulation of RC beams with mechanically fastened FRP strips

Simulating concrete cover separation in RC beams strengthened with near-surface mounted reinforcements

“…In light of this, it is proposed that the moment-rotation (M/h) technique [17][18][19][20][21][22][23] be applied to derive the required M/v relationships. The M/h technique applies the partial interaction theory [24][25][26] in order to simulate flexural cracking and tension stiffening by directly simulating the slip of reinforcements in the RC beam.…”

Concrete cover separation of reinforced concrete beams strengthened with near-surface mounted method: Mechanics based design approach

“…In response to all these problems, this article proposes a mechanics-based approach to design, which can prevent CCS failure while being less reliant on empirical means. An example of this can be seen in the work of Shukri and Jumaat (2016), where the moment-rotation ( M / θ ) approach (Knight et al, 2014; Mo et al, 2016; Oehlers et al, 2012; Shukri et al, 2015, 2016b; Visintin et al, 2013; Visintin and Oehlers, 2016, 2017) was used in conjunction with the global energy balance approach (GEBA) (Achintha and Burgoyne, 2013, 2011; Guan and Burgoyne, 2014) to simulate CCS failure. The M / θ approach is a mechanics-based method that applies the partial interaction theory (Gupta and Maestrini, 1990; Haskett et al, 2008; Muhamad et al, 2012; Visintin et al, 2013) to directly simulate concrete cracking, crack widening, and tension stiffening of RC beams.…”
