梁柱节点在单调荷载作用下的转动性能可以用构件法来预测，这种方法最近参照最常见的连接类型被编入了欧洲规范3。编码化的方法提供了从连接的几何和力学特性开始预测连接的初始转动刚度和抗弯阻力的规则。然而，尽管世界各地已经进行了大量的实验测试，但还没有建立预测连接塑性旋转供应的标准。首次尝试从理论的角度来面对这个问题，采用了组件方法(Faella等人，1997a，1997b)。特别强调的是，节点的塑性转角供应量基本上是控制节点抗弯能力的最弱节点构件的塑性变形能力与杠杆臂之间的比率。此外，还为螺栓联接中最重要的部件--T型管螺栓的塑性变形能力预测奠定了理论基础。
The rotational behaviour of beam-to-column connections under monotonic loads can be predicted by means of the component approach, which has been recently codified in Eurocode 3 with reference to the most common connection typologies. The codified approach provides the rules for predicting both the initial rotational stiffness and the flexural resistance of connections starting from their geometrical and mechanical properties. However, even though a significant number of experimental tests have been carried out all over the world, criteria for predicting the plastic rotation supply of connections have not been established.A first attempt to face the problem from a theoretical point of view has been developed by means of the component approach (Faella et al., 1997a, 1997b). In particular, it has been underlined that the plastic rotation supply of connections is, basically, the ratio between the plastic deformation capacity of the weakest joint component, governing the joint flexural resistance, and the lever arm. In addition, the theoretical bases for predicting the plastic deformation capacity of bolted T-stubs, ie the most important component of bolted connections, have been laid down.
