(According To Andrea and Norsa Formula) : Calculation of Foundation Blocks

This document provides calculations for designing foundation blocks based on material properties and load parameters. It calculates values such as the compressive strength of concrete (30 MPa) and yield strength of steel (420 MPa), foundation dimensions (width of 0.3m, depth of 0.6m), bearing pressure (15,000 kg/m2), material weights, vertical load (172.1 kg), stability moment (331.3 kg-m), and lifting hook capacity (97.5 kN) to determine that the designed foundation block is safe and can support the expected loads.

Calculation of Foundation Blocks

( According to Andrea and Norsa Formula )

(Compressive Convrete Cylinder Strength) fc' = 30.0 Mpa


(Steel Reinforcement Yield Strength) fy = 420.0 Mpa

( Flag Alloy Height ) hg = 3.1 m


( Total Base Service Moment ) Ms = 1536.0 N.m

( Foundation Width ) C = 0.30 m


( Total Foundation depth ) H = 0.60 m
( Exposed Height) h1 = 0.00 m
( Embdedt Height) h2 = 0.60 m

( Net Bearing Pressure ) q = 15000.0 Kg/m2


( Weight of Concrete ) gc = 2400.0 Kg/m3

(Shear Force at Pole Bottom) T = 1006.0 N

(Total Weight Of Metal Alloy) W1 = 42.5 Kg


(Weight Of Foundation Block) W2 = 129.6 Kg

( Total Vertical Weight ) N = 172.1 Kg

( Stability Moment ) Mst = 331.3 Kg.m

( Moment at Foundation Bottom Level) Mg = 2139.6 N.m


218.1 Kg.m

Mst/Mr = 1.52 >1.0 Safe Block

( Lifting Hook Dia.f ) = 20.0 mm


( Lifting Hook Capacity ) f N = 97.5 KN Satisfy Block Weight
