In this paper an experimental research on reinforced concrete irregular slabs with specific plane form and supporting condition is conducted, and the limit analysis of slab is discussed. The distinguishing features of the paper are selection of oblique strip and loading transmission, negative yielding line in irregular slab with simple supports, point support and shear split of slab.
Keywords: irregular slab; limit analysis; oblique strip; point support; shear split
