Extension of the <i>?</i> ?method for calculating deflections of two?way slabs based on linear elastic finite element analysis

Deflections are among the most complex aspects of reinforced concrete behavior. Furthermore, deflection control is increasingly a governing criterion in design, especially case two-way members such as flat slabs or edge-supported slabs. However, simple and theoretically sound adequately verified methods for calculating deflections have been lacking. Therefore, this study, novel method proposed The an extension ?-method (as defined by Eurocode 2 fib Model Code 2010) interpolating between uncracked fully cracked state. As basis, uses elastic that obtained through linear analyses finite element software. then transformed based on properties representative section, to account cracking, shrinkage creep according modified version ?-method. Finally, validated against available experimental results from literature, obtaining satisfactory precision accuracy. study aims at providing easy-to-use tool designers carrying out
