but results from studis of r . hansan and n . kishi have shown that only when the initial stiffness of connection is more than 105.05 kn-m / rad, the joint is considered as rigid connection, otherwise it should be dealt with semi-rigid connction 但根据r.hansan和n.kishi等人的研究表明,当螺栓端板连接的初始连接刚度大于10~(5.05)kn-mrad时,这种连接才可以看作是刚性连接,否则就应将其视作半刚性连接。
