“…Moreover, the resistance of lateral movement in the eccentric braces is through the bending of the column and beam [1]. Therefore, the links provides the ductility behaviour to counter the impact seismic force from the lateral excitation [17,18]. The strength, stability and ductility of the eccentric braced frame is influenced by the length of the horizontal links [5].…”

“…In addition, this is time consuming and expensive in the replacement of the horizontal links after it was damaged due to the seismic excitation [12]. However this causes the difficulties of the replacing or repairing the horizontal link beam since it is a primary component in the structure despite the high capacity of energy dissipation [12,17]. A vertical links is proposal to overcome the above disadvantages.…”

“…It does not lead to significant damage to the story beam since the internal energy dissipation and intensive inelastic deformation are accumulated in the links. Hence, the replacement of the vertical links is effective and easier than horizontal links after lateral excitation [17]. Table below shows the comparison of the characteristic, mechanism and latest improvement among the structural bracing for diagonal braced frames, chevron braced frames and eccentrically braced frames.…”

Abstract. Excessive lateral drift can contribute significantly towards crack formation, leading to structural damage. The structural damage will in turn reduce the capacity of the structure and weaken it from the intended design capacity. Generally, lateral drift is more pronounced in higher and longer structure, such as high rise buildings and bridges. A typical method employed to control lateral drift is structural bracing, which works by increasing stiffness and stability of structure. This paper reviews the influence of various types of structural bracing to structural performance of buildings. The history of structural bracing is visited and the differences between numerous structural bracing in term of suitability to different types of buildings and loading, mechanisms, technical details, advantages and limitations, and the overall effect on the structural behaviour and performance are dissected. Proper and efficient structural bracing is pertinent for each high rise building as this will lead towards safer, sustainable and more economical buildings, which are cheaper to maintain throughout the life of the buildings in the future.

“…Based on the findings of this research, deflection because of postbuckling leads to tension concentration excessive at the tip of the crack that grows by increasing crack length. During these investigations, a few studies have also been done to study the effect of cracks on thin panels under the pure shear, axial pressure, and axial tension . Researchers did some research about cracked corrugated plates.…”

Summary In spite of existing comprehensive studies on the behavior of steel plate shear wall (SPSW), some aspects of the SPSW have remained unknown, yet. One of the important aspects that is unknown is the crack effect on the SPSW behavior in linear and nonlinear zones. Some experimental studies have been reported that SPSWs were fractured due to crack propagation. Therefore, the crack effect on the behavior of SPSW should be accounted in considering of SPSW behavior. Although the effect of crack on the thin SPSW has been investigated to a limited extent numerically, stiffened SPSPW, especially diagonally stiffened SPSW, has not been studied. In doing so, in this paper, the effect of crack effect on the behavior of diagonally stiffened SPSWs is studied parametrically and numerically. Numerical results showed that stiffened walls exhibit better behavior in the presence of crack compared with SPSW in both elastic and inelastic zones. Because crack propagates in nonlinear zone, it has not effective on elastic behavior of diagonally stiffened SPSW. The effect of crack was also presented as mathematical equations to estimate load–displacement curve that are in agreement with the finite element results especially for wall thinker stiffeners.

“…Moreover, the external ED devices located at the bottom of the piers are more vulnerable to other natural and artificial factors, such as corrosion from water, impacts from vehicles, or floating debris. Replaceable shear links have been successfully applied in buildings [29][30][31][32] and bridges [33][34][35][36][37][38] as sacrificial elements to dissipate seismic energy. Inspired by previous research, this work proposes a novel pier system, which combines the advantages of both self-centering piers and replaceable shear links.…”

A double-column self-centering pier fused with shear links is a novel structure developed to reduce residual deformation and facilitate post-earthquake repair. With this novel structure, the seismic resilience of bridges can be improved, and the reliability of lifeline infrastructure can be ensured. This paper presents the proposed pier configuration and investigates the mechanical behavior of the pier. A simplified finite element model is established to develop the lateral force-displacement relationship under cyclic loading. Additionally, a theoretical model based on the matrix displacement method and the virtual work principle is proposed to calculate the lateral force-displacement skeleton curve. The rationality and reliability of the theoretical model are validated by the satisfactory agreement observed between the numerical and theoretical results. Furthermore, a series of parametric analyses are conducted to discuss the effects of key parameters. The outcomes of this work can serve as a reference for further development of the design method for the innovated pier.
