Tension member: gross and net section: worked example sheet in Equation Pad with typeset equations and results.

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.

# Material
f_y := 250 MPa
f_u := 410 MPa
gamma_m0 := 1.10
gamma_m1 := 1.25

# Plate 200 x 10 with two 22 mm holes
b_p := 200 mm
t_p := 10 mm
n_h := 2
d_h := 22 mm
A_g := b_p*t_p = mm^2
A_n := A_g - n_h*d_h*t_p = mm^2

# Design strength
T_dg := A_g*f_y/gamma_m0 = kN
T_dn := 0.9*A_n*f_u/gamma_m1 = kN
T_d := min(T_dg, T_dn) =
T_u := 350 kN
T_u <= T_d =
# Block shear (Cl. 6.4) must also be checked for the actual bolt pattern.
