钢筋混凝土梁、板的可靠抗剪性能是保证结构安全和使用性能的关键。可能的剪切破坏通常是脆性破坏，这强调了剪切承载能力的正确规范的重要性。剪切性能的知识正在稳步发展，现在很明显，旧的结构并不总是按照当代的要求设计的。不断增加的荷载-主要是桥梁-要求对现有结构进行评估，然后往往对其进行加固。因此，对混凝土结构在剪切中的实际性能的适当理解是首要的兴趣。
Reliable performance of beams and slabs in shear is essential for the safety and also for the serviceability of reinforced concrete structures. A possible failure in shear is usually a brittle failure, which underlines the importance of the correct specification of the load carrying capacity in shear. The knowledge of performance in shear is steadily developing and it is now obvious that older structures were not always designed in accordance with contemporary requirements. The increasing load – mainly on bridges – requires the assessment of existing structures, often followed by their strengthening. An appropriate understanding of the actual performance of concrete structures in shear is therefore of primary interest.
