title = "Experimental and numerical study of mechanical behavior of welded steel plate joints",
abstract = "This paper describes a study of welded steel plate joints using experimental and numerical methods. The objectives of this study are to observe the mechanical behavior of welded plate joints under monotonic and cyclic loads, identify their damage degradation processes, and provide useful test data for future damage analysis of beam-column connections in steel frame structures. Six specimens were designed, of which three were tested under monotonic loads, and the other three were tested under cyclic loads. The test setup consisted of three plates arranged in a cruciform and connected by two groove welds. The monotonic and cyclic loads were applied to the free end of the two outstanding plates, inducing a pulling force on the welded joint. Because the only element studied in the present work is the weld, the sizes of the three plates were kept constant. The responses of these welded plate joints are discussed in terms of their experimentally and numerically obtained mechanical parameters, hysteretic behavior, strain variations, stiffness degradation, damage process, and failure modes. The results show that the energy damage model outperforms the displacement damage model in terms of indicating the degree of damage. Furthermore, if designed according to code, all these welded plate joints perform satisfactorily.",

Funding Information: redistribution reduces the damage rate of the weld during the cycles of tension and compression. Compared with the test and numerical results of the second group of specimens, the maximum error of the hysteresis curve is 5%, and the maximum error of the skeleton curve is 8%, which could prove the reliability of the finite element model analysis. These results show that the mechanical mechanical parameters of the welds from the monotonic test could be used in the finite element mAccorodelding. to the verification of the three damage models for the specimens under the action of tension and compression cycles, it can be concluded that the changing trend and corresponding tension and compression cycles, it can be concluded that the changing trend and corresponding energy damage model obtained from these tests fits the damage curves better than that obtained energy damage model obtained from these tests fits the damage curves better than that obtained 4. fTrohme Et5h0e1c5ywcleilcdtemnastieorniaalnpdercformparnecsesipoanrtaemstest.ers obtained in this paper and the weld damage law 4.
