建立了半刚性钢梁柱节点的弯矩-转角关系，包括单腹板和双腹板角钢节点以及有或不带双腹板角钢的顶底角节点。节点的初始弹性刚度和极限弯矩承载力由一个简单的解析法确定。然后通过最小二乘曲线与普渡大学数据库中的实验测试进行拟合来确定形状参数。利用得到的节点初始刚度、极限弯矩和形状参数，建立了能够反映节点弯矩-转角关系的三参数动力模型。功率模型使用简单，能够真实地表示每种连接类型的实际弯矩-转角行为，并且可以很容易地在二阶框架分析中实现。
The moment‐rotation relationships of semirigid steel beam‐to‐column connections including single and double web‐angle connections and top‐ and seat‐angle connections with or without double web angle, are developed. The initial elastic stiffness and ultimate moment capacity of the connections are determined by a simple analytical procedure. The shape parameter is then determined by a least‐square curve fitting with experimental tests in Purdue University's data bank. Using the initial connection stiffness, ultimate moment capacity, and shape parameter so obtained, a three‐parameter power model adequate for representing the moment‐rotation relationships of these connections. The power model is simple to use and provides a realistical representation of the actual moment‐rotation behavior of each connection type with angles, and can be easily implemented in a second‐order frame analysis.
