描述了钢筋混凝土模型的粒子方法。钢筋采用有限元建模，并通过拉格朗日乘子与质点法耦合。该方法适用于非线性问题、中重度裂纹问题和可变形界面问题。应用于钢筋混凝土结构的静力响应，混凝土离散与粒子和钢筋与元素进行了说明。该方法还测试了几个静态的问题，不允许混凝土和钢筋之间的相对位移。
Particle methods for modeling reinforced concrete are described. The reinforcements are modeled by finite elements and are coupled to the particle method by Lagrange multipliers. The method is applicable to nonlinear problems, problems with moderate to severe cracking and deformable interfaces. Applications to the static response of reinforced concrete structures where the concrete is discretized with particles and the reinforcement with elements are described. The method is also tested for several static problems where no relative displacements between the concrete and the reinforcement are allowed.
