The maximum calculated pressure ($q_max$) must be less than the allowable bearing capacity ($q_all$).
The crane mast connects to the concrete base using either high-tensile anchor bolts set in a template or structural steel fixing angles embedded directly into the concrete pour. The foundation design must account for the localized stress concentrations at these connection points. 3. Step-by-Step Design Methodology Tower Crane Foundation Design Xls
Where A = base area (B² for square base) The maximum calculated pressure ($q_max$) must be less
– Consider inertial forces from crane slewing and load swinging, not just static loads. not just static loads.
