Using Eurocode $2$ answer the question The four$-$span slab shown in figure below supports a variable load of $3\mathrm{.}0$KN $/$ m $2$ plus floor finishes and a ceiling load of $1\mathrm{.}0$KN $/$ m$2.$ For a class XC$-1$ exposure, the cover to main bars $=25$mm $.$ Overall depth of slab $=170$mm $.$The characteristic material strengths are f $=25$ N $/$ mm$2$ and f $=500$N $/$ mm$2.$ Density of concrete is $25$kNm$-3.$ Assume the diameter of main bars to be $10$mm and links of $8$mm$.$ Design the continuous slab?
