“…They were composed of L or T steel cross-sections with reinforced concrete. Their force-displacement graphs are comparable to other numerical studies carried out, such as those by Yan et al [12], who analyzed the hysteretic curves and introduced the attenuation coefficient to represent the effects of seismic damage. They proposed a model that considers seismic damage and compared the model of hysteretic curves with experimental ones.…”

This research analyzes the solution of reinforced concrete joints reinforced with steel sections, known as steel reinforced concrete (SRC). The aim is to verify the improvement of the ductile characteristics of steel reinforced concrete structures compared to conventional reinforced concrete structures. Another objective is to better understand the experimental behavior and thus be able to perform numerical simulations adjusted with the experimental ones. In addition, the behavior of reinforced concrete structures in all the bars with steel sections is compared with others in which only the joints are reinforced to obtain more efficient and economical structures. All these objectives have the main purpose of improving the behavior of structures against seismic loads. Five specimens of concrete joints with reinforced with steel were tested with cyclic loads to analyze their behavior. The strength superposition method can predict the shear strength. The results obtained confirm the greater capacity of absorption of energy of the structures with sections of steel embedded compared with the structures of conventional reinforced concrete, with greater ductility when facing large displacements.

A numerical model for the analysis of frame structures that is capable of reproducing the behavior of reinforced concrete (RC) members and steel-reinforced concrete (SRC) members in all steps until collapse by simulating a reduced resistance capacity is presented in this work. Taking into account the solid models obtained in previous research that have been validated by experimental results, moment-curvature graphics were obtained in all steps: elastic, plastic, and post-critical to collapse. Beam models versus 3D models considerably simplified the calculation of frame structures and correctly described both the plastic and post-critical phases. The moment-curvature graph can be used in a simplified frame analysis, from post critical behavior to collapse.

“…As shown in Figure 7, the slope of line bc is the reverse loading stiffness K 2 . Using the same method as in Section 3.2.1, the degradation law curve and its regression formulas of the reverse loading stiffness K 2 of each specimen can be obtained, as shown in Figure 9 and equations ( 4) and (5). e regression formulas of K 2 are as follows:…”

“…In recent years, a series of research studies have been carried out on the load displacement relationship models of various new structures under repeated loads. Yan et al established the hysteretic model of the joints between steel reinforced ultrahigh strength concrete columns and steel reinforced concrete beams and put forward the quantitative method of seismic damage and attenuation coefficient [5]. Zhang and Han proposed a prediction model for cyclic lateral load deformation response of RC columns subjected to axial compression and cyclic shear; comparison between the predicted cyclic response and experimental results indicates that the proposed model can predict the observed hysteretic response of flexureshear critical RC columns well [6].…”

In this paper, two joints of circular tubed steel-reinforced concrete (CTSRC) column were designed. The load-displacement hysteretic curve and skeleton curve of this new type of joint are obtained by the pseudostatic test under low cycle cyclic load on the top of the column. The results show that this new type of joint has good seismic energy dissipation performance. On the basis of the test, a three-fold skeleton curve model considering three characteristic points of yield, limit, and failure is proposed, and the expression of skeleton curve model is given. The load and unload stiffness degradation law of specimens under reciprocating load is studied, and the expression of stiffness degradation law is given. The hysteresis law of the new type joint specimens is described in detail. The validity of the model is verified by comparing the experimental curve with the model curve. The model can be used in the elastic-plastic seismic time-history analysis on the joint of circular tubed steel-reinforced concrete (CTSRC) column.
