Abstract

In this research, the structural behavior of similar depths flat plate panels specimens with different shapes has been studied. Three shapes of panels were used; square panel, triangular panel and trapezoidal panel. Each shape has two amounts of steel fibers (0.5% and 1%) in addition to reference specimen (free of steel fibers). The effects of panel shape and amount of steel fibers on failure pattern, ultimate capacity and cracking capacity have been adopted in this research. The test results concluded that irregular shape of panels have ultimate capacity and cracking capacity more than the square panels. Also, ultimate capacity and cracking capacity is affected increasingly by using steel fibers in concrete mixture. The steel fibers exchange the failure pattern from punching shear failure to flexural failure. The failure pattern also exchanged from punching shear failure to flexural failure in case of irregular panels shapes.
