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.

“…Prior research looked into deflection, ductility, strength, energy dissipation response, reinforcement detailed requirements, stiffness, and drift reversals. Many scholars [11][12][13][14][15][16] have carried out combined experimental and numerical investigations on the performance of BCCs. [17] described a numerical evaluation of the seismic behaviour of shear deficient BCC.…”

An experimental investigation studied performance of Scorner beam-column connection (BCC) under cyclic loading. Each BCC consisted of upper, lower column and two beams; one of them was free end (A) while the other was fixed end (B). The cyclic loading was applied on the end of beam (A) while the beam (B) was unloaded and subjected to torsion stresses due to fixation. Two variables were investigated. The first is the eccentricity of the beam about column edge while the second is the effect of stirrup joint configuration on BCC under cyclic loading. All BCCs were tested under reversible fourteen cycles. The vertical displacement at the free end of the beam (A), horizontal sway at mid height of the column, crack and ultimate loads were observed in details at each cycle. The findings noticed that the increase of stirrup length in the connection decreased the deflection at the same level of the load. The ultimate load of specimen, which was shifted by 25mm, was less than the ultimate load of specimen, without shift, by 24%.When the joint stirrup was extended outside the column core by 50 mm in specimen Sp2, the capacity of the connection increased.
