Assume a 6m x 6m x 1.5m pad (Area = 36 m², self-weight = 36 1.5 25 = 1,350 kN).

Before diving into calculations, engineers must understand the load combinations from the crane manufacturer’s data sheet. Typical ultimate limit state (ULS) loads include: tower crane foundation design calculation example link

Lever arm (distance between two bolt rows) = 1 m. Tension force per bolt pair = 4,500 / 1 = 4,500 kN / pair. Per bolt = 2,250 kN. This is too high – thus, increase bolt size or embedment. Assume a 6m x 6m x 1

Maximum pressure under moment: [ \sigma_max = \fracV_dA + \frac6 \cdot M_dB \cdot L^2 ] ( A = 25 , m^2 ) ( M_d = 1.5 \times 2600 = 3900 , kNm ) (wind case)
