| Résumé: | The rate of applying cruciform columns with bolted connection in double-directed Moment resisting frames and tubular systems has positive trend because of their architectural advantages. Construction of doubler plate for shear strengthening panel zone and continuity plate, with regard to special moment resisting frame requirement, needs convenient detail which is presented in this research. There was no applicable information in this research filed, so new constructional details involving of inclined plates and vertical angles were presented in order to strengthen the panel zone. Furthermore, the different welding configurations were studied. For this reason, 16 nonlinear numerical models were simulated to study different constructional detail of panel zone. In present research, steel material and weld behavior were evaluated by fracture indexes of material. Results show the performance of panel zone will be improved by using proposed constructional details. |
