design results and discussions

The design results for the studied six flat slabs having irregular column layout are illustrated in Table-1. These slabs are also analysed and designed using the computer software (SAFE) and the results obtained using the simplified design method are also compared with the SAFE software results. Moreover, the deflection results obtained in each slab is compared with the ACI code limit (L/360) and are shown in the last column of table-1. The deflection results showed that all of the six selected slab sections have deflection values less than the allowable deflection according to the ACI code of design (ACI 318-14) indicating good and safe design. The detailed design for two of the slabs (FS-3 and FS-6) are also provided in this section. The deflection contours for the studied slab models obtained from the SAFE software are shown in figure-3.
