Abstract

Abstract

In order to study the bearing performance of stainless steel core plate (SSCP) floor considering brazing residual stress (BRS) distribution, the BRS in 25 single-unit specimens of SSCP were determined by hole-drilling method and X-ray diffraction method, and the simplified predictive model for the BRS distributions in SSCP was proposed. The proposed simplified model, as the initial defect, was introduced into the finite element model (FEM) of the three-point bending test of the SSCP floor, and the reliability of the simplified distribution model is verified by comparing the calculation results of the FEM considering the BRS distribution and without BRS distribution with the test results of the SSCP floor, and the FEM was parametrically analyzed. The test and research results show that the recommended peak value of tensile BRS for the simplified predictive model is 0.6σ_0.2. The FEM considering the BRS distribution is able to accurately simulate the bearing performance of the SSCP floor. Calculated shear stiffness of the FEM considering BRS distribution is more accurate.
