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.

最近在2019年进行了一次剪力试验建模竞赛。来自欧洲各大学和咨询公司的团队应邀来预测两条钢筋混凝土梁的剪力。数值模型的基础将根据荷兰NLFEM指南RTD 1016-1：2017建立。在竞赛中，选择了由代尔夫特理工大学测试的两根没有箍筋但具有较大深度（1200毫米）的钢筋混凝土梁作为建模目标。比赛的大多数参与者都没有与测试结果达成良好的一致。本文针对以下两个测试之一进行了事后预测研究：H123。基于此研究，对RTD 1016–1：2017的建议进行了一些调整，以更好地接近测试结果。
