“…The second problem consists in the non-linear inelastic response of the RC beam-column joint (see Figure 9), with important plastic strains that can lead to the soft story mechanism in current engineering practice. In the research paper of Khan et al [44],"the need to consider the shear hinge in RC beamcolumn joints" is confirmed, such that "the model has different stiffness degradation in tension and compression" [14].…”

The MR RC frame structures present a special engineering interest regarding the practical mode of ductile seismic response, through plastic hinges formation in specially designed RC beams end areas and inferior zones of the RC columns from the ground floor. Thus, it was proposed to verify the capacity design concept for this structural system type through seismic response observation of the optimal MR RC frame model. Until this objective is achieved, it was proposed to perform a complex analytical study, which has as finality the current research paper. Thus, in the previous analytical studies the influence of the concrete strength class, the influence of the longitudinal steel reinforcement ratio in RC columns and influence of the RC beams cross sections on the local and global seismic response for a group of RC frame models were analysed. In these conditions, the present paper contains the results obtained in previous research papers and concludes the current analytical study through the observation of the effectiveness of the inferior longitudinal steel reinforcement ratio in the RC beams on the cracking mode, in potentially plastic areas. Finally, it was specified that the K_7 RC frame model represents the optimal structural system for the experimental test.

“…As mentioned before, FEM calculations were performed with Abaqus software [ 28 ] using the Concrete Damaged Plasticity model (CDP) for concrete. There are many other alternative models, e.g., presented in the work Marzec et al [ 15 ] or Cichoń and Winnicki [ 29 , 30 ]. The CDP model for monotonic loading was mathematically formulated by Lubliner et al [ 31 ] and enhanced by Lee and Fenves [ 32 , 33 ] for dynamic and cyclic loading.…”

This paper discusses a choice of the most rational reinforcement details for frame corners subjected to opening bending moment. Frame corners formed from elements of both the same and different cross section heights are considered. The case of corners formed of elements of different cross section is not considered in Eurocode 2 and is very rarely described in handbooks. Several reinforcement details with both the same and different cross section heights are presented. The authors introduce a new reinforcement detail for the different cross section heights. The considered details are comprised of the primary reinforcement in the form of straight bars and loops and the additional reinforcement in the form of diagonal bars or stirrups or a combination of both diagonal stirrups and bars. Two methods of static analysis, strut-and-tie method (S&T) and finite element method (FEM), are used in the research. FEM calculations are performed with Abaqus software using the Concrete Damaged Plasticity model (CDP) for concrete and the classical metal plasticity model for reinforcing steel. The crucial CDP parameters, relaxation time and dilatation angle, were calibrated in numerical tests in Abaqus. The analysis of results from the S&T and FE methods allowed for the determination of the most rational reinforcement details.

Despite this trade-off, the smeared crack approach remains a valuable tool for conducting large-scale fracture analyses and optimizing designs [35].

In the present work, the fracture performance of pre-cracked reinforced concrete beams was investigated numerically and experimentally. Experimental and numerical programs were designed to examine the effect of beam width, b, (120 and 250 mm) and crack-to-depth ratio, a/d, (0.1, 0.2 and 0.3) for concrete strength, fc, (40 MPa), on the behavior of stress intensity factor, K1C, and fracture energy, G, for reinforced concrete, RC, beams. The work utilized beams with three-point loading conditions experimentally. Through the use of the ANSYS program, a comprehensive 3-D finite element analysis was conducted with utmost precision to simulate and idealize all experimental specimens. It has been confirmed through numerical and experimental outcomes that the stress intensity factor for RC concrete beams experiences a significant increase as the a/d increases. Furthermore, the fracture toughness values in this study show a slight increase due to the utilization of RC concrete beams with wider width. The validity of the presented concept was demonstrated by comparing the experimentally measured load vs. deflection values to the predicted numerical values and finding them to be acceptable.
