STRUCTURAL BEHAVIOR OF A REINFORCED CONCRETE ARCH CULVERT (PHASE 3-CEDAR CREEK)--SECTION V (VOLUME 1): DATA ANALYSIS BY NEUTRAL POINT METHOD (THEORY)

A flexibility approach is employed to establish a computer code to assess internal forces in an arch culvert, due to application of external soil stresses and footing movements, using the neutral point (elastic center) method. Input may be in the form of measured soil stresses acting on individual voussoirs based on experimental measurements or on horizontal and vertical effective densities. Footing movements include observed or hypothetical, horizontal and vertical displacements of the right footing with respect to the left, and rotations of both with respect to a datum level. Output includes resisting moments, thrusts, shears, wall displacements and fiber stresses in concrete and reinforcing steel. A separate code for plotting results on a XYNETICS plotter is included. The text includes algorithm derivations, flow charts program listings and sample input and output for hypothetical boundary conditions. /FHWA/
