Just would like to comment on min spacing of slab reinforcement (reference @13:29 time stamp) as specified by NSCP particularly section 425.2.1 where minimum clear spacing of bars shall be at least the greatest value of 50mm, diameter of the bar and 4/3 times the size of aggregates. Whereas, this NSCP provision i suppose was lifted from ACI 318 code, and according to the code in section 25.2.1 Forparallel nonprestressed reinforcement in a horizontal layer, clear spacing shall be at least the greatest of 1in or 25mm, db, and (4/3)dagg. This made me confuse of which one to use? 50mm or 25mm?
Pag nasa dulo yung slab, one end continuous un. Pag nasa gitna, both end continuous. pag cantilever, fixed yung isang end, free yung isa. Pag simple supports (hinge and roller), simply supported.
