Design and testing of cone and hypar footings
Model cone and hyperbolic paraboloid footings were tested to observe membrane and bending stresses and to measure soil pressure distributions under footings; variations in pressure distribution under shell footings due to soil arching are discussed; design equations are given for cone and hyperbolic paraboloid footings; solution is obtained for optimum vertex angle of cone footing to minimize concrete plus reinforcing steel costs; results are shown as graph; second graph facilitates economic comparison of cone and square footings, based upon unit cost ratios of concrete and steel in each footing type.
