“…A major breakdown of the FAM has been achieved when the concept of FAM 3D was introduced [10]. The 3D case of FAM was addressed in [11] for the analysis of structural models subjected to long-duration time-histories of wind loads and for the assessment of the structural damage state.…”

“…The concept of axial force-bending moment interaction surface, coupled with an efficient return mapping algorithm was used [12]. Although the main features of the FAM 3D modeling technique were introduced in [10], there are several topics that were not fully addressed. An obvious issue in [10] is that the usage of material bilinear model is arguable for modeling cyclic behavior of reinforced concrete (RC) elements.…”

The structural engineering community often deals with the issue of inelastic incursions of the structural response. Although buildings situated in seismic regions are usually designed using elastic analysis, most encounter significant inelastic deformations when major events occur. In general, material nonlinearity is the most important source of nonlinearity considered in the dynamic analysis commonly performed in structural design. In this paper, the recent concept of the force analogy method for 3D structures is developed and integrated into an accurate computational efficient algorithmic routine for nonlinear dynamic analysis of reinforced concrete frames. Moreover, a unique straightforward mathematical model for the numerical implementation of degrading cyclic behavior of structural elements is proposed and further used to simulate the response of a 10 story reinforced concrete frame structure. A set of nonlinear dynamic analyses are performed using the proposed algorithm in order to assess the structural damage in case of different peak ground accelerations seismic recordings. The seismic structural damage is evaluated using both structural response parameters expressed in terms of displacement and energy concepts.
