DESIGN FOR STRENGTHReinforcement:
0.751 mm
2 MPaNº of bars = 2
157.08d = 95 mm
4.8 MPa
The maximum pier reinforcement is calculated as:
206.29
The reinforced pier moment capacity is calculated as:
4.855 kNm > 4.103 kNm OK!
DESIGN FOR OVERTURNINGThis spreadsheet assumes the footing pad to be central to the pier when determining the required size of the footing pad.The footing pad is also assumed to be have a square geometry.Other geometries, or footing pads eccentric to the pier are not considered in this spreadsheet.
The calculations for determining the footing size are done as follows:
