Abstract
Attempts are made herein to account for the cause of those considerably frequent slab damages, attended with large deflections, which occur over an L-shaped balcony R.C. slab cantilevered out at a building corner, as those over a group of L-shaped slabs encountered relatively of late. For the purpose of that theorizing their scaled-down models were prepared, subjected to test loading and the obtained sets of data are compared with corresponding finite element solutions based on suitable idealizations including treatments of material nonlinearity and cracking effect. The results are examined on statical characteristics of those slabs and some considerations are deduced therefrom on their reinforcing design and on an existing likelihood of their inaccurate execution which is even more sensitive to those damages.
