This document serves as the backbone for the following calculations. The example report covers a crane operating at a 70m radius, with a hook height of up to 52 meters and a substantial overturning moment of 4,781 kN·m, making it an ideal real-world case study for a medium-to-large tower crane project. Wf=B×B×D×γccap W sub f equals cap B cross

$$ A_s = \fracM_u \times 10^60.87 \times f_y \times 0.95 \times d \approx \frac348.7 \times 10^60.87 \times 460 \times 0.95 \times 1350 \approx 722\ \textmm²/m $$ $$ A_s = \fracM_u \times 10^60

When a tower crane pierces the skyline, the public marvels at the height and the reach. Engineers, however, look down. The most critical component of a towering steel leviathan isn't the jib or the counterweight—it is the invisible block of concrete buried beneath it.
