钢筋混凝土实心板桥的抗剪能力是通过将设计梁抗剪力与由于永久作用和活荷载而施加的剪力的设计值进行比较来评估的。半比例连续板桥的实验结果用于制定一套评估板桥剪力的建议。提出了一种考虑集中荷载下板中横向力重新分布的方法，以及集中荷载的水平荷载分布方法。对于现有直实心板桥的选定案例，根据荷兰规范 NEN 6720 基于抗剪承载力的结果与欧洲规范 (EN 1992-1-1:2005) 与建议相结合的结果进行了比较，显示出更好的一致性。
The capacity of reinforced concrete solid slab bridges in shear is assessed by comparing the design beam shear resistance to the design value of the applied shear force due to the permanent actions and live loads. Results from experiments on half-scale continuous slab bridges are used to develop a set of recommendations for the assessment of slab bridges in shear. A method is proposed allowing to take the transverse force redistribution in slabs under concentrated loads into account, as well as a horizontal load spreading method for the concentrated loads. For selected cases of existing straight solid slab bridges, a comparison is made between the results based on the shear capacity according to the Dutch Code NEN 6720 and from the combination of the Eurocode (EN 1992-1- 1:2005) with the recommendations, showing an improved agreement.
