Abstract
The introduction of strut-and-tie models in fib Model Code 1990
as a design basis for discontinuity regions constituted a significant
step toward promoting consistent design methods for reinforced concrete
structures. In fib Model Code 2010, the scope was broadened
through the stress field method that was introduced as a complementary
tool. The present article summarizes subsequent evolutions in both
methods, which will be incorporated in the upcoming fib Model
Code 2020. Besides emphasizing their suitability for the structural
design and assessment, their adaptability to the
“Levels-of-approximation” approach is also depicted. This article
presents the theoretical ground of both methods and looks on their
potential for computer-modeling implementation. With this respect,
several strategies are presented by discussing their advantages and
optimum field of application.
