  5.2 REQUIRED REINFORCEMENT

  5.2.1 Reinforcement Formula

- Shrinkage and temperature reinforcement

 As = fac b h , fac = 0.002 ---- ACI CODE 7.12.2

- Required Reinforcement by Analysis

 As As 2 

- At every section of flexural members where tensile reinforcement is required

  As As 5

  As As 4

- The requirements of Eq (6.3.2) need not be applied, if every section As provided is

at least one -third greater than that required by analysis

 As2 = r .req b d

  As3 = 1.333 r .req b d

  As4 =1.4

  As5 =0.25 f  ck

Selected As = Max ( As1 , As2 , Min ( As3 , Max ( As4 , As5 ) ) )

  If Selected As < Using As < As max , then OK!!

Note : The reinforcement is calculated bases on the maximum moment under the foundation in each direction.

But, the 'ISO' , 'OCT' , 'HEX' , 'COMB' , 'TANK1' foundations are calaulated as face pier
