Abstract:The effect of pattern loading on the bending behavior of a concrete flat plate is examined. A finite element bending analysis is used to investigate the influence on moment and deflection ratios of column flexural stiffness, aspect ratio of panels, ratio of clear span to center-to-center span of support columns, and the boundary conditions at the edge of the plate. The concrete plate is assumed to be a homogeneous isotropic material. The results indicate that moment and deflection ratios decrease nonlinearly with increase of columns stiffness and are dependent on the panel aspect ratio and the ratio of clear span to center-to-center span. Moment ratios are generally small for sup-port moments and are smaller for exterior spans than for interior spans. Empirical formulas are presented to predict the moment ratios for both interior and exterior spans.
