  • The bending strength of the end plate and the column flange is determined by the yield line method. The yield line method can be calculated by the energy or virtual work method.

...

  • Strong column, strong joint connection and weak beam are used to compute the forces on the bolts and to find the required bolt strength. According to this assumption, the column panel zone and beam exhibit inelastic behaviour while the connection and column show elastic behaviorbehaviour. For this reason, it is necessary to design the end plate as a thick plate. In thick plate behaviour, the force in the bolts is the static moment at the center of the compressive part.
