using newest versions (Bentz, 2015)
compared with experimental result by Mikel et al (2016)
for case of reinforced concrete wide-beam or slabs, ACI codes and software from Bentz (1997) given under-estimate results about 26.8% and 38.6% respectively.
in case of normal beams,
compare with test result by Mikel,
still the result shown under estimate about 15,6% however it’s look better than wide-beam case, discrepancy may come from stress discontinuity in disturbed region (?) it may required to conduct 2D or 3D nonlinear FE for studying.
**updates using newest versions (2015)
Based on Shear-Moment interaction for shear force at V=63.2kN, shown bending moment M=28.8kN*m still lower than experimental results.
oldest and newest version has shown no slightly different.
