RISA | Why does my slab deflection increase using ACI 318-19?
21-12-2021· For slabs that fall into this category, a larger deflection will be present when utilizing the ACI 318-19 code. For the ACI 318-14 code, the ratio is roughly 0.58 while the ratio in the ACI 318-19 code is approximately 0.25. Comparing these values to the graph plotted above, we see the ACI 318-19 code renders a larger value of Ma/Mcr, which,Permissible Deflection in Slab - CIVIL SITE VISIT,27-04-2019· Permissible Deflection in Slab.
