Application of Strut-and-Tie Method for Railway Reinforced Concrete Structure

摘要

In some foreign countries, the strut-and-tie method (STM) is an effective path to solve D-regions problem. Because of better mechanical concept and higher precision compared with traditional design method, the STM is extensively applied to design and calculate the regions where the strain distribution is nonlinear (internationally called D-regions). In this paper, on the basis of concept and principle of the STM, the requirements, procedures and aspects demanding attention of developing strut-and-tie models are reviewed. In addition, uniqueness of these models is also discussed. At last, two designing examples are studied to demonstrate the application of the STM in the railway reinforced concrete structure.
