Nomograms for the Calculation of Pressure and Passive Resistance of Cohesionless Soils

THIS paper deals with a class of arch known as the “Stabbogen.” The arch is loaded through the hangers which may be referred to as “wire-hangers” since they are assumed to be simple tension members having comparatively small flexural rigidity. The hangers are connected to a rigid chord at their lower ends, and thus become inclined when the arch rib deflects laterally. The load is considered to be applied by means of a horizontal thrust H at the ends of the rib instead of through the hangers. Chin Fung Kee
