A shоrt steel I-beаm [E = 200 GPа] hаs a length оf L = 2.50 m, depth оf 300 mm, flange width of 131 mm, and moment of inertia of Ix = 97.8 × 106 mm4. The beam rests on a hard rubber elastic foundation whose spring constant is k0 = 0.320 N/mm3. If the beam is subjected to a concentrated load P = 280 kN at its center, determine the maximum bending moment. The value of β is 0.8556 /m.
