-Concrete cover value is entered as 3 cm. (Basically, the net concrete cover value should be at least 5 cm.) - For a more economical reinforcement design, the raft reinforcement axes can be arranged so that they do not overlap the columns and curtains. (For example, between 1-2 axles and HI axles) - Analysis option can be evaluated by ticking the "Enlarge connection area" line for "Rat foundation-superstructure connection method" in Analysis Settings/Foundation-Soil Tab. -Larger reinforcement diameters can be selected from the reinforcement selection dialog, especially for additional reinforcements. Good work
