Abstract:
Develops general theoretical methods to evaluate crack- Develops general theoretical methods to evaluate cracking behavior, deflection, and ultimate strength of curved behavior, deflection, and ultimate strength of curved reinforced concrete flexural elements. Primary attention reinforced concrete flexural elements. Primary attention directed toward development of rational methods for directed toward development of rational methods fo evaluating the structural behavior of circular reinforced evaluating the structural behavior of circular reinforced concrete pipe under three-edge bearing loading. The concrete pipe under three-edge bearing loading. The methods ure applicable for design of pipe in accordance methods ure applicable for design of pipe in accordance with criteria established in ASTM C 76 and other specifications with criteria established in ASTM C 76 and other Methods developed for ultimate strength analysis or Methods developed for ultimate strength analysis or design of pipe are applicable with all types of reinforcing design of pipe are applicable with all types of reinforcing steel. The general method of investigation given for cracked steel. The general method of investigation given for cracking and deformation analysis is valid with all types of reing and deformation analysis is valid with all types of re-inforcing steel. Quantitative relations suggested for analysis inforcing steel. Quantitative relations suggested for analysis cracking and deformation behavior apply only to pipe cracking and deformation behavior apply only to pipe reinforced with certain types of welded wire fabric reinforced with certain types of welded wire fabric reinforcing. reinforcing. Cracking and ultimate strength results from 197 three- Cracking and ultimate strength results from 197 three-edge bearing tests on full-sized pipe are compared with edge bearing tests on full-sized pipe are compared with calculated strengths and provide good corroboration of calculated strengths and provide good corroboration of the theory in most cases. Where test results were used to the theory in most cases. Where test results were used to obtrain semiempirical constans in theoretical relations other test results were available for checking. other test results were available for checking.
