Easy to use and comprehensive spreadsheet for designing reinforced and unreinforced concrete strip footings. Allows to apply axial, bending moment and/or horizontal loads. Supported wall can be positioned centrally or eccentrically on the footing. The spreadsheet checks uplift, overturning, sliding, bearing pressures. Where reinforced concrete footing is required the spreadsheet designs reinforcement for bending and shear. Required reinforcement is plotted on an easy to understand 'live' diagram. The diagram also gives foundation sizes for a quick check. The spreadsheet includes pop-up messages with help information.
