Plate Connection

This paper studies structural behaviour of the blind bolted connections to concrete-filled steel tubular columns by a serial of experimental programs, which conducted involving eight sub-assemblages of cruciform beam-to-column joints subjected to monotonic loading and cyclic loading. The moment-rotation hysteretic relationships and failure models of the end plate connections have been measured and analyzed. A simplified analysis model for the blind bolted connections is proposed based on the component method. It is concluded that the blind bolted end plate connection has reasonable strength and stiffness, whilst the rotation capacity of the connection satisfies the ductility requirements for earthquake-resistance in most aseismic regions. This typed joint has excellent seismic performance, so it can be used in the moment-resisting composite frame.

Plate Connection

A series of retrofitted extended end-plate connections have been tested experimentally and evaluated using the component method specified in Eurocode 3. The component method decomposed the end-plate connection into several components, including the tension zone, compression zone, vertical and horizontal shear zone that occurred at the bolt, end-plate, beam and column. Based on the theoretical model, the moment resistance and the initial stiffness of a connection can be predicted. Four experimental tests on the retrofitted extended end-plate connections have been conducted to verify the proposed design method. From the experiment tests, all moment resistance of the connections showed good agreement with theoretical predictions, which establish a reliable foundation to predict the moment resistance of the retrofitted end-plate connection. All initial stiffnesses calculated from theoretical predictions do not represent the actual behaviour of tested connection. All tested connections can be classified as partial strength based on EC 3: Part 1.8, in condition the welding capacity is at least 50% higher than the capacity calculated from the component method.

Specially Shaped Column

This paper brings forward a new kind of specially-shaped column and its end-plate connection joint with H-section beam. The static loading and cyclic loading simulation tests of the joint are carried out using the finite element software. Under static load, the moment-rotation curves with different parameters are obtained, and then the effects of those parameters on the initial stiffness and the ultimate moment and the stress distribution of key positions of the joint are discussed; under cyclic load, the moment-rotation hysteretic curves are obtained and mechanical behaviors of the basic test specimen are comprehensively analyzed. The results indicate that the joint possesses not only reasonably high initial stiffness and ultimate capacity, but also excellent ductility and energy-dissipation capacity.

This paper presents an analytical study on flush end-plate (FEP) and extended end-plate (EEP) connections connected to cruciform column section using component method. The objective of this study is to predict the moment resistance and initial stiffness of FEP and EEP connections on cruciform column section. A series of FEP and EEP connections are tested in laboratory. The connection tests consist of four FEP and four EEP specimens with different configuration. Component method outlined in the publication of Steel Construction Institute and British Constructional Steelwork Association are based on BS5950 and Eurocode 3 (EC3) are used to predict the moment resistance and initial stiffness of the tested specimens. The experimental results are then used to validate the analytical predictions. As compare to the experimental results, all moment resistance of the connections coincide well with analytical predictions. Analytical prediction for initial stiffness using EC3 does not show good agreement with the experimental results. This study shows that the component method can be used to predict the moment resistance of FEP and EEP connections on cruciform column section. Further study need to be carried out for initial stiffness to obtain accurate analytical representation.

The Web

End plates welded transversely to the web of the beam and then bolted to the supporting member should provide effective, simple connections to transmit shear. However, under loading, the end of the beam rotates and moments are developed in the connection. It is essential that the end plate connection be sufficiently flexible so that the factored moment can be attained in the beam without the development of excessive moments in the connection itself. Based on the behaviour of T-sections, where the flange of the T simulates the end plate and the stem simulates the web of the beam, both when the stem is loaded in tension and in compression, analytical procedures have been developed to predict the moment–rotation behaviour of end plate connections. Good agreement has been obtained between the predicted nonlinear moment–rotation curves and the experimental curves for eight connections covering a practical range of end plate thicknesses, gage distances between bolt holes, and connection depths. With the proposed analytical expressions the designer is able to predict the behaviour of a connection to ensure it has sufficient strength and flexibility. Key words: beams, connections, deformation, design, end plates, plates, rotation, shear strength, steel, stresses, tests.

Steel Section

The objective of this paper is to present the behaviour of composite beam using Trapezoid Web Profiled (TWP) steel section by determining the moment resistance and the deflection of the beam with composite and non-composite connections. The TWP steel section is a built up section where the flange is of S355 steel section and the corrugated web of S275 steel section. Three full scales testing setting-up as sub-assemblage frame have been carried out. It was concluded that the use of composite connection and extended end-plate has reduced significantly the deflection and has significantly increased the loading capacity of composite beam.
