Abstract:
. The conduit is first considered to be divided into two parts, the base slab and the arched frame. The fixed-end moments, fixed-end shears and stiffness value for the arched frame are presented by formulas and graphs. From these values and similar well-known values for the base slab we may determine the final moments in the conduit by a single distribution of moments at one corner by the usual method of Moment Distribution. A “shear correction factor” is given to change the fixed-end shear of the frame to the final shear. The formulas and graphs take exact account of the conduit wall thickness and special con- siderations are given to the indeterminate state of strain in the corner region.
