Slab cracks and defornations caculation follow Vietnam standard compared with Safe software

Abstract

     Deformations and cracks of structural reinforcement concrete caused affect such as aesthetic appearance and requires use of structural system. In calculations, it is usually considered that the bearing capacity is limited to the limitation state 1, but considered rarely the limit deformations and cracks follow limitation state 2 (TCVN 5574-2014). On the other hand, the calculation of deflections and cracks follow Vietnam Standard TCVN 5574-2012 also have some difficulties in design. In this paper, the presentation of the deflection and cracks of the reinforcement concrete slab with Vietnam Standard TCVN 5574-2012 compares the results with the SAFE software is calculated with American Standard ACI 318-2002, Europe standard Eurocode 1992-2 have different load cases. From there, make evaluations and conclusions.
