End-plate connections are very often used is steelwork, as tension and bending connections. As a result of deflection of end plate, additional forces, known as prying forces arise and consequently increase stresses in bolts. Eurocode 1993-1-8 do not distinguish end-plate connections prestressed by high strength bolts from non-prestressed. The aim of the paper is to perform the comparison of previous analytical models and code regulations for coefficient of prying forces to the experimental tests and modelling by finite element method. Results of the analysis show that the behaviour of prestressed connection is essentially different with comparison to non-prestressed.

Static stability analysis to 12 kinds single-story steel frames with I-section columns is analyzed based upon bilinear lateral force versus displacement framework curve and finite element method, then ultimate displacements are obtained. In comparison, the framework curves and ultimate displacement calculated by modified stiffness and cross-section plastic moment theory accord with that calculated by finite element method. This provides the referential basis for the static stability analysis to a single-story steel frame.

3D Integer models of steel portal frames are made to analyze the influence of end-plate bolted connections on internal force and displacement of frames by using finite element method. The results show that end-plate bolted connections are semi-rigid connections, and the flexibility of the connections affects the behavior of the frames, and their influences can not be ignored in the steel portal frames design and analysis.

Steel portal frame is easy to build,but the connection styles of end-plate have greater influence on the structure. In this paper, The formula about initial stiffness of end-plate connections has been given.The essay uses ANSYS to analyze the initial stiffness of end-plate connections. Several factors have also been analyzed about the stiffness.The conclusion is that the form of end-plate, thickness, bolt diameter all affect the structural deflections.But these reasons couldn’t change the integral moment of the structure.
