Strength Design of Reinforced Concrete Hydraulic Structures. Report 5. Experimental Study on the Ultimate Behavior of Model Reinforced Concrete Circular Conduits.

Abstract

A test program was initiated to investigate the two-dimensional failure response of reinforced concrete (R/C) circular conduits under a known 16-point loading. This was achieved by testing 18 R/C models to failure. The test specimens were instrumented to obtain concrete and steel strains and intrados deflections at the crown and springing line. Steel percentage ratios, loading distribution, and curvature were varied for each test. All models failed primarily in flexure; ductile and brittle failure modes were observed. In a later test program, models which were exposed to 2-point and 4-point loadings and the three-edge-bearing method failed in diagonal or radial tension. Keywords: Aqueducts, Hydraulic models, Hydraulic structures, Reinforced concrete.
