Normalized Stiffness and Resistance for Extended End-Plate Joints.
As a result, the normalized stiffness of extended end-plate joints can be approximately evaluated by means of a generalized cubic function, such as:
The average ratio of theoretical and experimental values of moment resistances was 0.87, for extended end-plate joints, and 1.07, for flush end-plate joints.

The Beam with Slant End-Plate Connection Subjected to Nonsymmetric Gravity Load and Uniform Temperature Increase.
In conventional end-plate connections (vertical), after an increase in temperature, the beam tends to yield or buckle due to increase in axial force.
The structural model described in the previous section has been used to analyse a steel beam section at elevated temperature, in which an IPE 300 beam is connected at its ends to slant fixed end-plate supports (Figure 7).
The curve of axial force due to only nonsymmetric gravity load ([P.sub.i], Q) starts from 187 kN (angle = 2[degrees]), in vertical end-plate position and it goes to zero by increasing the angle of slant connection.
