Abstract

A recent contest of shear tests modelling was carried out in 2019. Teams from universities and consultancies around Europe were invited to predict the shear capacity of two reinforced concrete beams. The basics of the numerical models were to be set up according the Dutch NLFEM Guideline RTD 1016–1:2017. In the contest, two reinforced concrete beams without stirrups but having large depth (1200 mm), tested at Delft University of Technology, were selected as the modelling target. Most participants in the contest did not obtain good agreement with the test results. This paper presents a postdiction study on one of the two tests: H123. Based on this study, some adaptations are made to the recommendations of RTD 1016–1:2017 in order to approach the test results better. The intention of this contribution is to improve the existing NLFEA Guideline for practical engineering structures with uncommon reinforcement layouts.
