Cracked moment of inertia slab
Webmoment of inertia ofthe cracked transformed section. In order to include the effect of reinforcement on the properties of uncracked section, lg in Eq. (2) can be replaced by lu, the moment of inertia ofthe uncracked transformed section to yield the following equation for Ie: (3) The use oflu in place oflg has already been recommended by Branson ... Webimplementation of internal cracks are reduced this process. Failure of rc structures will reduced by this post-cracking system. In rc flat slab the punching shear problem is reduced gradually and it become beneficial behavior by combination of SFRC [3]. A simple technique in construction filed the flat slab is a simple and easy construction.
