ABSTRACT
Composite plate shear walls with concrete filled (C-PSW/CF) are widely used in industrial and high-rise buildings due to construction convenience and excellent load-bearing performance. However, buckling of the steel plate is an important factor and is difficult to consider in C-PSW/CF. In this paper, based on the column-supported rotational-constraint (CSRC) plate model, the uncertainty analysis of the plate buckling behavior was conducted. Three types of uncertainties were considered with random fields, and stochastic finite element models were generated. The simulation results illustrated that morphology fluctuation of steel plate surfaces with small correlation lengths can significantly reduce steel plates’ buckling resistance. Furthermore, an engineering case of corrosion was analyzed, and it was suggested that the buckling resistance of corroded shear walls needs to be taken into account.
