1. sabrukuma shēma
σy = 350 MPa
Pieņemtais profils - IPE 240
Wpl = 367 cm3
Mpl = σy * Wpl = 350 * 103 * 367 * 10-6 = 128.5 (kN*m)
Qx = HA – q*x
x = HA/q = 10/2 = 5(m) (maksimālā momenta punkts)
WM = Mpl * 2 * Ө = 256.9 * Ө
Wq = q * A = qcr * Ө * 25
WM = Wq
256.9 * Ө = qcr * Ө * 25
qcr = 10.3 (kN/m)…
