Rigid Pipe Proof Testing Under Excess Overfills with Varying Backfill Parameters. Section V (Volume 8). Neutral Point Analysis Output: Quasi-Theoretical, Concrete, Extreme Fiber Stresses

摘要

The neutral point analysis described in SECTION 5 (Volume 1) was employed to determine quasi-theoretical extreme fiber stresses at the inner and outer peripheries of the walls of the Cross Canyon, reinforced concrete culvert, using normal and tangential tractions modified to satisfy equilibrium considerations. A 400 psi (2760 Kilonewtons per square meter) line has been included on the profiles to designate and anticipated limiting concrete tensile stress. Quasi-theoretical boundaries of cracking of the culvert's inner wall indicated by intersections of the inner fiber stress profiles with this limiting stress line are compared with observed cracking limits in SECTION 8: Analysis of Distress.
