slab

e and lap splices ensure continuity of reinforcement. Design codes such as ACI, Eurocode, or IS 456 provide guidelines for minimum reinforcement ratios and detailing. Material Selection Concrete grades typically range from M20 to M40 for

nvironmental loads, if relevant (wind, seismic forces) Since hollow blocks reduce dead load, this calculation often results in a lighter overall structure compared to solid slabs. Step 3: Design Reinforcement Using ACI 318 guidel
