Plate Connection

Steel construction allows fast and economical method of construction which also fulfills the requirement of clients. Especially low-rise building such as industrial building is the most common in steel frame. There are few common types of connection that are commonly being used in the industry such as flush end plate connection and extended end plate connection. This research is conducted to evaluate the performance of end plate connection as the common steel connection in low-rise buildings. Software ConSteel is used to evaluate the performance of identified connections by analysis. At the end of the research, an optimize design of end plate connection maybe recommended based on the performance and serve as a basic of improvement and guidance of safety.

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.

During the European research project entitled EQUALJOINTS (European pre-Qualified steel JOINTS) [1], which recently concluded, the matter of providing a set of pre-qualification procedures for moment resisting beam-to-column connections which are currently used in Europe has been addressed. During the experimental campaign 24 specimens with bolted extended end-plate connections with haunches were tested. The current paper presents the numerical model which has been developed such that numerical testing may be performed to further investigate specific details. In what concerns the material, an isotropic material model has been calibrated and used based on tensile tests of coupons extracted from the specimens to model the actual plastic behaviour. Moreover, the imperfections of the beam have been taken into account using a bucking analysis to model as accurate as possible the specimens tested. The interaction between parts has been modelled using contacts with different interaction laws. The model used for the bolt has been calibrated such that the preloading and failure replicate the behaviour of the actual bolts used in the experiments.

Plate Connection

Steel frames can be designed as simple, semi-continuous, and continuous construction. However, these types of constructions depend on the type of connections used. Connections are usually classified in design as pinned which is associated with simple construction or rigid which is associated with continuous construction. However, the actual behaviour in most cases is classified as semi-rigid connections or partial strength. The semi-rigid connections usually associated with the stiffness of the connection while the strength of this connection usually associated with partial strength. The use of semi-rigid connection has been encouraged by Euro-code 3 and studies on the matter known as semi-continuous construction have proven that substantial savings in steel weight of the overall construction. A series of parametric studies on two bays of two, four, six, and eight storey of multi-storey braced steel frame are presented in this paper. All frames are designed using S275 steel and flush end-plate connection was used as connection for semi-continuous construction whereas fin plate connection was used for simple construction. The frames are designed both as simple construction and semi-continuous construction and the steel weight of the frames was calculated and compared. From the parametric study it was found that by using partial strength connection the saving in steel weight of the frames is in the range of 11.5% to 22.5% of the total steel weight of the frames.

The Ideal

Based on the investigation of end plate and angle of semi-rigid connection in the steel frame of beam-column, an analysis of two connection type damage phenomenons, stiffness, bearing capacity and ductility, and then with the experimental results concluded above, the similarity and differences between the two semi-rigid connections can be extensively discussed. And with that， it can naturally be concluded that the end-plate connection is a good load capacity and ductility properties of semi-rigid connection type. These for, the conclusion can provide test basis for the ideal steel structure semi-rig seismic node design and application.
