Example only. This sheet shows one way to set out the check. It is not endorsed by the bodies that publish the design codes and does not reproduce them. Check every clause, value and assumption against your own copy of the current edition of IS 800 before you use it, and have the result checked by a competent person. See the disclaimer.
The calculation, line by line
Every line below is typed into Equation Pad exactly as shown; the app typesets it, works out the value with its units and shows checks as TRUE or FALSE. Change any input and everything below it updates.
# Inputs
P_u := 800 kN
f_ck := 25 MPa
f_y := 250 MPa
gamma_m0 := 1.10
b_c := 200 mm
B_p := 300 mm
# Bearing
f_b := 0.6*f_ck =
A_req := P_u/f_b = mm^2
A_p := B_p^2 = mm^2
A_p >= A_req =
w_b := P_u/A_p = MPa
# Thickness
a_p := (B_p - b_c)/2 = mm
b_p := a_p
t_s := sqrt(2.5*w_b*(a_p^2 - 0.3*b_p^2)*gamma_m0/f_y) = mm
# The base plate may not be thinner than the column flange.How to use this example
