3. SEISMIC BEHAVIOUR OF BOLTED END PLATE BEAM-TO-COLUMN STEEL JOINTS based on elemental components as defined in the Eurocodes. An alternative within the same philosophy was then explored employing macro-components, as the coupled Tee stubs, which take into account the influence of the key components in the compression and tension zone of the joint as well as of their interactions. The schematic model of the joint is represented in Figure 3.25. The responses of joints JA1-2A and JB1-3A were simulated by means of this model and compared with the connection experimental responses, modified to achieve consistency. Figure 3.26 shows such a comparison for the joint JA1-2A. The overall agreement all over the response is quite good, and is confirmed by the curves of the cumulated energy illustrated in Figure 3.27. According to these first results, the macro-component model appears a viable tool for approximating the cyclic response of end plate joints. Figure 3.25. Macro-component method 73
