“…In their research, steel plates connected to the beam only were investigated. They proposed Equation (17) to estimate the tension field action. Since the boundary conditions of the steel plate and the proposed damper presented in this study are similar, the equation is used to calculate θ.…”

“…Numerous passive metallic dampers, as a device indirectly added to brace members, have been developed to improve the hysteretic behavior of the CBF systems. For instance, Steel plate‐based dampers: ADAS, [ 13,14 ] TADAS, [ 15,16 ] rhombic, [ 17 ] single round‐hole, [ 18 ] X‐shaped, [ 19 ] slit, [ 20,21 ] comb‐teeth, [ 22 ] parabolic, [ 22,23 ] prebent strips [ 24 ] and curved steel dampers, [ 25 ] and shear damper. [ 26,27 ] These dampers exhibit suitable seismic performance; however, they require high‐quality manufacturing. Dampers made as links: EBF, [ 28–30 ] vertical shear links, [ 22,23,31,32 ] shear damper, [ 33,34 ] and knee braces, [ 35,36 ] U‐shaped steel, [ 37 ] torsional beams, [ 38 ] tapered cantilevers, [ 39 ] and tapered tube dampers.…”

Although concentrically braced frames (CBFs) possess high lateral stiffness and strength, the buckling of compressive members indicates that a system does not have appropriate ductility. Therefore, CBF is not a successful system for high seismic regions. Comprehensive studies have been performed on this drawback concerning CBF systems. The use of a metallic damper is considered an appropriate method to enhance the behavior of CBFs. While metallic dampers improve the hysteretic behavior of the CBF, they impose additional costs on the structures. Therefore, in this study, a steel damper, which is economical and straightforward to construct and replace after a severe earthquake, was developed. The proposed damper was investigated experimentally and numerically. In addition, a parametric study was performed to evaluate the effect of the three types of damper mechanisms (shear, shear-flexural, and flexural) with three types of buckling (elastic, inelastic, and plastic) on the behavior of the proposed damper. The experimental results, as well as the numerical results, indicate that the shear damper exhibits better performance than the other dampers in terms of strength and stiffness. Except in the case where the shear damper is accompanied by plastic buckling, it has a higher energy dissipation capability. In addition, a flexural damper with elastic buckling cannot be considered as an energy-dissipating device because of the fracturing of the damper due to displacement near the elastic zone. Fundamental relationships were used to predict the behavior of these dampers, and these predictions showed good agreement with the finite element results.

Glazing facades generally represent one of the most critical building components, from a structural point of view, since providing a physical separation and barrier for the building occupants. In this regard, especially under the action of extreme loads, they require specific design concepts voted to protect the building occupants. In this paper, the feasibility and potential of special mechanical connectors interposed at the interface between a given multi-storey primary building structure and the glazing facade are investigated via accurate finite-element models, under the action seismic and explosive loads. Given the case study of a 4-storey steel framed structure enclosed by a glazing curtain wall, both the global and local effects and potential benefits due to additional vibration control systems (VCSs) are preliminary assessed via numerical simulations, giving evidence of the activationonce properly designed-of a distributed-tuned-mass damper (TMD) concept involving the glass facade as a structural component of the 3D building. Differing from traditional TMD applications in civil engineering systems-namely consisting of lumped mass, damping and stiffness terms-these beneficial contributions are derived from the enclosing glass panels. Taking advantage of earlier research studies, in particular, where major efforts have been spent for the potential of viscoelastic VCSs, careful consideration is paid in this paper for the feasibility of elasto-plastic (PL) connectors,

“…Designing a building with these devices requires a full knowledge of hysteretic behavior in dampers as well as their precise number and location in the structure. There are different types of metallic yielding dampers, among them are the triangle added damping and stiffness [9], ushape damper [10], rhombic steel damper [11], circular hollow damper [12], and slit steel plate (SSP) damper. Developing countries prone to earthquakes could be interested in this type of seismic protection given its low cost.…”

The use of perforated metallic shear dampers in buildings has been an adequate strategy for reducing the magnitude of damages caused by earthquakes on primary elements. Furthermore, the amount of energy dissipated by the shear dampers is in turn affected by the geometrical shape of said perforations. Such process is carried out without knowing the most adequate shape or distribution of perforations in relation to an established amount of material.In this research, 5 different steel sheer damper setups will be compared in order to determine how this affects performance and to understand how damper perforation shape affects energy dissipation capacity. The latter is achieved through a performance analysis of dampers under a cyclic load using the finite element analysis software Abaqus. Likewise, the decrease in response to a seismic event of a plane frame will be measured using three different seismic motions for all the different setups used for the researched shear plates
