When a partially exposed reinforced concrete beam deforms under tensile loading on reinforcements, the load-carrying capacity of the exposed reinforced concrete beam will significantly change, as the deformation of the exposed reinforcement bars and concrete do not follow a harmonising relationship. In this paper, the load-carrying capacity of a partially exposed reinforced concrete beam was investigated. By analysing a large quantity of test data, the changing patterns of the load-carrying capacity were obtained and two typical failure modes of the exposed reinforcement concrete were summarised. In the study, finite-element software was employed to simulate the test results. The simulated values were consistent with the test results. An extensive analysis of the influencing factors using a finite-element method was conducted. The length of the exposed reinforcement and the reinforcement ratio were considered as the controlling variables to obtain the changing failure modes of the exposed reinforced concrete beam. The analytical results confirmed the conclusions of a previous analysis.

部分暴露的钢筋混凝土梁的承载能力研究

当部分暴露的钢筋混凝土梁在钢筋上承受拉伸载荷时发生变形时，暴露的钢筋混凝土梁的承载能力将发生显着变化，因为暴露的钢筋和混凝土的变形不遵循协调关系。本文研究了部分暴露的钢筋混凝土梁的承载能力。通过大量测试数据的分析，得出了承载能力的变化规律，总结了裸露钢筋混凝土的两种典型破坏模式。在研究中，使用有限元软件来模拟测试结果。模拟值与测试结果一致。使用有限元方法对影响因素进行了广泛的分析。以裸露钢筋的长度和钢筋配比为控制变量，以得到裸露钢筋混凝土梁的变化破坏模式。分析结果证实了先前分析的结论。
