Large Reinforced Concrete Special Moment Frame Beams under Simulated Seismic Loading

Numerical modeling of rebar buckling in reinforced concrete members using truss analogy

“…Nonlinear truss modeling approach is verified by experimental test results of one RC beam tested by Visnjic et al [23]. Visnjic et al studied [23] experimental cyclic behavior of two large RC beams, namely Beam#1 and Beam#2 with various hoop spacing subjected to vertical tip displacements.…”

“…Visnjic et al studied [23] experimental cyclic behavior of two large RC beams, namely Beam#1 and Beam#2 with various hoop spacing subjected to vertical tip displacements. Section reinforcing details of Beam #2 with reduced hoop spacing is shown in Figure 7.…”

Nonlinear Beam-Based Modeling of RC Columns Including the Effect of Reinforcing-Bar Buckling and Rupture

“…Experimental research is the most reliable means of investigating the performance of RC frame components and the impact of bar buckling and subsequent rupture on component performance. Visnjic et al (2016) conducted experimental tests on full-scale RC beams designed in accordance with current guidelines for special moment frames. The hysteretic response was affected by bar buckling, which was evident in the observed damage pattern, as shown in Figure 1a.…”

“…Examples of rebar buckling and rupture, as observed in experimentally tested RC components: (a) Beam (Visnjic et al 2016); (b) bridge column (Hose et al 1997). …”
