“…The representativeness principle can be extended for various structural problems (e.g., References 35 and 54 ), though experimental setups must be verified accordingly. For example, the representativeness of the 80 × 80 × 640 mm prism (Figure c) was improved by increasing the length of the specimen up to 1000 mm.…”

Regardless of the simplicity of the test layout, interpretation of the tensile test results may be inadequate. Typically, a test of the reinforced concrete tie provides measurements of average deformations of the internal reinforcing bar and the concrete surface. The experimental evidence, however, often contradicts with the general assumption of the similarity of mean strains of the reinforcement and concrete. Analysis of the sources influencing the scatter of the experimental results motivated this investigation of the representativeness of the specimens. In this study, the representativeness is understood as a property of a tie to isolate the investigated parameters (e.g., the deformation components) from other uncontrolled effects typical of test with limited sample sizes. This study aims at determining the representative geometry of the test samples that would enable the reduction of the end effect. A consistent procedure is proposed for identifying the cracking parameters of the ties with different testing layouts.

“…Therefore, the second suggestion 5,14 consists in providing the same reinforcement in the two chords of the beam, making the section symmetrical; • Lateral springs: the presence of the orthogonal structural systems can highly and positively influence the response of the structure when a supporting column collapses, as demonstrated in Refs. [19][20][21][47][48][49][50][51] In general, the horizontal flexural-shear response of the orthogonal beams combined with the slabs can produce "3D effects" with important benefits.…”

This study develops a 2D computational parametric analysis of ordinary reinforced concrete (RC) frames, located in seismic zone, with the aim to evaluate some design suggestions with respect to their effectiveness in increasing the structural robustness. Specifically, a five‐storey and four‐span 2D RC moment resisting frame is considered, designed in a highly seismic area according to both Italian and European codes. Subsequently, respecting the seismic design code provisions through a cyclic design procedure, some modifications are suggested regarding the layout of the longitudinal reinforcement bars of the beams to exploit the continuity, Vierendeel behavior and influence of the side face reinforcement bars in the beams. For the different modifications, nonlinear finite element pushdown analyses of the whole frames are performed by imposing a monotonically increasing vertical displacement at the point of the column removal in Atena‐2D and considering the presence of the orthogonal framed systems. Furthermore, two different failure scenarios are examined. The numerical force‐displacement capacity curves corresponding to the different proposed design suggestions are investigated and compared. The results have demonstrated the effectiveness in improving the structural robustness of the proposed solutions, especially, of the side face reinforcement bars with respect to both flexural and catenary behavior. The outcomes have also highlighted the compatibility between design criteria of both robustness and earthquake engineering.
