| 摘 要： | 基于ABAQUS的混凝土损伤塑性模型的有限元建模可以较好地模拟钢筋混凝土开孔梁整个受力过程,该文建立一批开孔梁试件有限元模型。通过对开孔梁的受力性能进行参数化分析,探讨孔长、孔高、孔洞位置对开孔梁的极限承载力和刚度的影响,对孔洞的设置提出了一些有用的建议。

| Abstract: | Adopting the concrete model accounting for plastic behavior caused by damage, finite element modeling can stimulate the whole loading process of RC beams with openings. Through a parametric study on the mechanical behavior of beams, the effects of length, height, position of openings on the ultimate capacity and the stiffness of beams are investigated. Some useful suggestions on collocation of openings are proposed. |
