Sumbols and conversion of figures:
- Maximum allowable moment – Mmax [kNm / m]
- Elasticity resistance (plasticity limit) of the material- f0 [MPa], [kN * 1000 / m * m *](Mpa = N / mm * mm = N / 0.001 m * 0.001 m = kN / m * 0.001 m = 1000 kN / m * m)
- Modulus of section - W [cm * cm * cm / m], [0,01m * 0,01m * 0,01m / m],[m * m * m / 1000000m]
Mmax = f0 * W [(kN * 1000 / m * m *) * (m * m * m / 1000000m)] = f0 * W / 1000 [kN * m / m]
Calculated load-bearing capacity at flexing of a 1m wide GP-6 wall (maximum allowable moment):
Mmax = f0 * W / 1000 = 516.73 * 541.4 / 1000 = 279.8 [kN * m / m]
Mmax = f0 * W / 1000 = 516.73 * 2453.9 / 1000 = 1268 [kN * m / m]
