Research on the End-Plate Thickness of Extended End-Plate Connection in Plastic Hinge Theory
The extended end-plate connections widely used in steel frames, at home and abroad，many countries have given varieties of different methods to determine end-plate thickness. This paper, uses the plastic theory to analyze the end-plate thickness of the figure 7.2.9a in CECS 102：2002 specification, adopts small deformations of geometric relations and the equal principle of work both inside and outside, the prying force issue is considered according to whether deformation bolts do work, and finally discuss the design process of the end-plate thickness. Contrasting present norms, this method can significantly reduce end-plate thickness.
