“…Similarly, the addition of 30 kg/m 3 and 60 kg/m 3 of steel fiber increased the θ u value by 20% and 118.8%, respectively, relative to the reference sample. The researchers reported that the addition of steel fiber contributed significantly in the increase the maximum resisting torque and maximum twist of RC beams under purer torsion[31,32,36]. The addition of steel fiber also increased torsional moment at cracking (T cr ) and the angle of twist per unit length at cracking (θ cr ).…”

Concrete is widely used structural material, all over the world. The excellent versatility, availability, and economy of the concrete makes it a pioneer of the construction industry when it is compared to other materials. Beams/columns are one of the main structural elements of building to respond to the effects, such as bending moment, shear, and torsion. Thus, it is important to investigate the relevant behaviors of members [1,2]. Steel fibers have been used to improve the characteristic properties of concrete in practice for many years. Besides the commercial use of fibers in concrete technology began in 1970s, particularly in Europe, Japan, and USA. In the structural application, concrete behaves as a brittle material with low tensile strain capacity and with some softening postpeak behavior in compression essentially due to the transverse strain capacity. The use of steel fibers in the

“…The study of [8], which uses HSS rebar as the shear reinforcement in beams, can increase the width of cracks at service load levels and showed different failure behavior due to the development of flexural compression zones on structural members experiencing shear. In this study, using HSS as shear reinforcement met the limits of ACI 318-19 [9] but also showed shear stress failure when the yield strength of the shear reinforcement exceeded 600 MPa.…”

This paper presented a nonlinear finite element analysis of lateral loading RC shear walls with regular openings using the 3D-NLFEA program. The RC shear walls model was generated from the available test results in the literature. To model the concrete under a complex stress state, a multi-surface plasticity model which combines compression failure surface with tension cut-off failure surface was used. The model was intended to look at the load-displacement relationship and the crack pattern between the model and the numerical model. In addition to the numerical model verification, parametric studies were carried out to investigate the use of high-strength steel (HSS) of the two different grades (Grades 100 and 120) to replace all the normalstrength steel (NSS) or only some of it. The parametric studies found that the shear wall with the NSS bar demonstrated higher stiffness and achieved higher lateral load with the lowest extent of damage (compared to the RC shear wall with the HSS bar). On the other hand, using the HSS bar resulted in lower stiffness, lower lateral load, and higher damage region, which was expected as more strain is required to yield the HSS bar.

“…In a paper by Lee et al (2021), an experimental study is presented on the use of HSR steel for the shear and torsional design of reinforced concrete structures. Through the testing of 73 specimens under shear and 42 specimens under torsion, as well as other specimens from the literature, it is concluded that the current code limit for the maximum steel yield strength can be increased for shear reinforcement, but not for torsional reinforcement.…”
