“…In general, the relatively stiff parts of a shear wall will resist all earthquake forces. Ductile coupling beams must connect coupled shear walls with limited ductility [1,6]. Because they are subjected to substantial inelastic deformations at their ends, coupling beams must have a high ductility.…”

The Open Ground Story (OGS) building is a functional need of all urban areas so cannot be eliminated. According to studies from previous earthquakes, when there is severe earthquake shaking, Reinforced Concrete (RC) frame buildings with open ground levels function badly. In this work, four models of G+14 RC frame buildings with and without a shear wall, coupled sheal wall, and diagonal strut were modeled and analyzed using ETABS-2018 software's static and dynamic response spectrum method. Model 1 open ground story RC building without strut and the shear wall was compared to the other three models that included a shear wall, coupled shear wall, and diagonal strut. As a result of the findings, it has been determined that shear wall, coupled shear wall, and diagonal strut not only increased the stiffness but also reduced displacement. A model with a combination of shear wall and coupled shear wall showed a minimum base shear and overturning moment than all other models.

“…The reinforced concrete shear wall plays an important role in high‐rise structures because of high lateral stiffness and great seismic capacity. [ 1,2 ] Due to the needs of architectural opening (e.g., doors and windows), coupling beams are often designed to connect shear wall piers, which can enhance the lateral stiffness and ductile behaviors compared with individual shear wall piers, forming the reinforced concrete coupled shear walls. There have been many studies on the seismic performances of the shear walls with various detailing measurements.…”

Summary Structures with replaceable energy‐dissipating elements are attractive systems for improving building resilience. Damage in these structures is mainly limited to dissipating elements, which can be replaced after earthquakes. Among the energy‐dissipating elements, viscoelastic dampers (VEDs) can dissipate energy even under small deformations while providing stable fatigue performances, which benefits high‐rise buildings in resisting both wind and earthquake loadings. This paper presents the seismic design of an engineering practice of a 10‐story shear wall building with replaceable viscoelastic coupling beams. A new type of viscoelastic material that has negligible frequency dependency is adopted to provide stable constraint for the wall piers. The design details, including VEDs, nonreplaceable segment, and the detachable connection, are exemplified. The numerical model of the replaceable structure is established and analyzed under dynamic loadings. Results confirm that the implementation of replaceable viscoelastic coupling beams improves structural seismic performance. The plastic rotation at the end of the coupling beam is significantly reduced up to 41.4% compared with the traditional coupled shear wall structure.

“…Beside their seismic performance, the composite shear walls present other structural advantages as: reduced thicknesses, multiple possibilities to connect the walls with steel or composite frames, a reduced construction erecting time or costs by using prefabricated steel profiles. In the existing literature different types of composite steelconcrete shear walls were experimentally and theoretically investigated: isolated walls (Olabi, 2021; or coupled shear walls (Li, 2019) both systems developing a great seismic performance. By coupling the isolated piers with horizontal beams, the overall seismic performance of the system is influenced by the hysteretic resistance of the coupling beams or by the geometric position of the openings (Zhang, 2021;Liu, 2023).…”

The lateral resisting system comprised of hybrid shear walls is often met nowadays for high rise buildings, to reduce the lateral displacements of the building during a seismic event and to limit the damages of non-structural elements. In fact, “hybrid shear walls” term will replace the old terminology used for composite steel concrete shear walls. This structural system develops a very stable seismic behavior under cyclic lateral loads, but the seismic performance of the system could be significantly changed by the openings required for architectural or functional reasons. This paper presents in detail the seismic behavior of a composite steel-concrete shear wall designed with centered openings and partially embedded steel profiles in the edges. The composite wall was subjected to vertical and horizontal loads and tested to full failure using a cyclic loading testing procedure that simulated the action of an earthquake, aiming to record the seismic performance of the wall in terms of bearing capacity, deformation capacity, failure mode and stiffness degradation. The low-dissipative behavior recorded experimentally of the tested specimen was afterward validated and assessed in detail by performing numerical analyses using ATENA 3D Engineering software. The numerical results were extended to investigate furthermore other structural solutions to increase the bearing capacity and the seismic performance of the wall. It was found that a significant increase in deformation capacity could be obtained if the wall coupling beams are reinforced by diagonal steel bars or additional steel plates.
