چکیده
abstract: Reinforced concrete flat slabs are structural systems in which directly supported by columns, without the use of beams. A phenomenon that deserves attention these is punching shear, characterized occurrence shear stresses close to slab-column interface, can produce fragile rupture those regions. This study presents some results reliability index β obtained for connections based on FORM, according Brazilian standard’s model, considering model error. The critical contours C and C’ reinforcement analyzed. showed failure contour very unlikely, while probabilities C' when influence error greater than target values recommended literature ULS.
