Design workflow (step-by-step) 2) Loads you must consider (typical) 3) Bearing capacity & foundation size (quick formulas) Areq=Wtotal / qallow​​ where Wtotal = vertical load + self weight of foundation, qallow – allowable soil bearing pressure (kN/m²). 4) Natural frequency / dynamic criteria (must check) fn=1/2π(sqrt(k/m) )where k= effective stiffness of foundation system (N/m), m Read more
