Based on the reinforced concrete constitutive laws presented in the previous chapter of the book, behavior of R/C structures can be foreseen. So, it was stated that the fundamental feature of reinforced concrete structure behavior is its non-linear character. Within the present chapter methods for elastic and post-elastic analysis under static loads are examined as applied to reinforced concrete frames. Initially, “classical’’ pushover analysis is examined. Further, the plastic analysis through “limit equilibrium’’ (sometimes referred to as Simple Plastic Theory) with its theorems and practical applications is briefly presented and commented. It is demonstrated that the rotations of plastic hinges depends upon the moments plastic redistribution only and, accordingly, practical procedure for post-elastic design of concrete structures which keep under control the magnitude of plastic rotations is derived. Some numerical examples aimed to illustrate the theoretical considerations are included.
