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.

This paper is principally performed to survey end-plate connection are described in the next part based on ideal limit states. The determination of end-plate based on the full plastic strength of the steel beam in accordance with 2001 AISC-LRFD manual and AISC/ANSI 358-05 Specifications. The bolted connections considered herein were performed to include the end-plate component of moment connections. This study is intended to investigate economic design for end-plate connections. In addition, the proposed end-plate model is evaluated by comparing the required factored bolt strength. The end-plates using 8 high strength bolts with wider gages demonstrated this design. The equations belonging to the step-by-step design procedure are described based on complete proving of design. Finally, new design methodology is applied to end-plate connections suggested in this study.

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.
