The force distribution is determined iteratively. New in this version of XFrame2d is that the beam-to-column moment connections can be entered directly and that the rotational stiffnesses of all connections are determined in each iteration step. Based on the moment occurring in the member connection, the rotational stiffness diagram of the designed connection (see the figure below) is used to determine a rotational stiffness, or spring stiffness, which is then used in the next iteration step. The iteration stops when no more changes occur in the force distribution.\u003C\u002Fp>\n\u003Cp>XFrame2d therefore takes a load-dependent rotational stiffness into account for all moment connections. This of course gives the most accurate result and leads to an economically optimal design.\u003C\u002Fp>\n\u003Cp>For small moments (below 2\u002F3 Mj,Rd) the initial rotational stiffness Sj,ini is used. For larger moments the rotational stiffness Sj that corresponds to the bending moment Mj,Ed is used. The trilinear rotational stiffness diagram is applied here. See the diagram below.\u003C\u002Fp>\n\u003Cp>\u003Cimg src=\"\u002Fnewsletters\u002Fimg\u002F2018-08-13-momentvaste-ligger-kolom-verbindingen-in-xframe2d\u002F02-399.webp?v=196c70fc8e3f\" width=\"399\" height=\"233\" alt=\"Diagram of moment Mj against rotation with Mj,Rd, 2\u002F3 Mj,Rd and the rotational stiffness Sj to be used; connection classified as flexible\" loading=\"lazy\" decoding=\"async\">\u003C\u002Fp>\n\u003Ch3>The steel structure can now be a lot cheaper\u003C\u002Fh3>\n\u003Cp>By already taking a flexible connection into account in the design of the main load-bearing structure, instead of a fully rigid connection, the connection can become much cheaper and a correct force distribution is calculated. With XFrame2d the lead structural engineer quickly and easily makes an economical design of the main load-bearing structure, including the beam-to-column moment connections.
