Abstract:
A summary of the work done by Committee 312 since the publication of its progress report in 1932, and presents for discussion a suggested specification for reinforced concrete arch design. Further investi- gation has been made of the effects of shrinkage and plastic flow. Measurements on large arches at Pitts- burgh over a period of years are presented and dis- cussed along with the results of other investigations. Recommendations are made as to the calculations of moments and thrusts due to loading and volume changes, A new method is proposed for the design of the arch rib based on ultimate strength formulas and a new approach to the question of factor of safety for members subjected to direct load and flexure.
