Design of Reinforced Concrete Members Under Flexure or Combined Flexure and Direct Compression

摘要

It is the purpose of this paper to suggest a complete revision of the method of designing reinforced concrete members subjected to bending and to present a rational method for the proportioning of arch ribs, rectangular columns under eccentric load, and rectangular beams. This method may be extended to cover the design of T beams, round columns and any other form of concrete members. Simple formulas are given which predict the ultimate strength with remarkable accuracy based on the cylinder strength of the concrete and the yield point of the steel independent of the ratio of their moduli of elasticity. It is believed that these equations will greatly simplify the work of the designer and result in the more efficient and economical use of reinforced concrete. The suggestions are intended to place structural concrete design on a solid practical foundation which is now justified by the advance in construction practices, the availability of better materials, and the information gained by a great amount of research work.
