“…The RSE design philosophy is most applied to coupling beam between wall systems. Fortney et al firstly proposed a new type of fuse coupling beam (FCB) [21,22], as shown in Figure 4. It is assumed that all inelastic deformations will be concentrated in the middle section (fuse section) of the beam such that the two outer steel beam parts could be protected.…”

This paper presents a review of high performance damage-resistant seismic resistant structural (DRSRS) systems for the sustainable and resilient city. Firstly, the motivation and the basic principle as well as methodology of the developing DRSRS system are briefly illustrated. Then, the structural detailing and the seismic behaviors of three types of existing DRSRS systems, namely, the replaceable structural element (RSE), rocking seismic resisting structural (RSRS) system, and self-centering seismic resisting structural (SCSRS) system, are summarized in detail. The theoretical and extensive experimental study results indicated that the three existing types of DRSRS system can minimize the postdamage after loading. Types of energy dissipation devices and dampers, as well as fuse sections, can largely enhance the energy dissipation capacity of the proposed structural system. Many numerical and finite element models have been proposed to analyze the dynamic and static cyclic responses of them. The residual deformation after the dynamic response is smaller compared to that following the cyclic response. Then, the current research challenges of DRSRS system are illustrated, and the new research highlights that emerged in recent years are stated. Finally, the conclusions of this paper are summarized; furthermore, the recommendations for the future studies are pointed out at the end of the paper.

Abstract:Resilience-based earthquake design for next-generation super-tall buildings has become an important trend in earthquake engineering. Due to the complex structural system in super-tall buildings and the extreme computational workload produced when using refined finite element (FE) models to design such buildings, it is rather difficult to efficiently perform a comparison of different design schemes of super-tall buildings and to investigate the advantages and disadvantages of different designs. Here, a simplified nonlinear model is developed and applied to compare two design schemes (the fully braced scheme and half-braced scheme) of a super-tall mega-braced frame-core tube building, which is an actual engineering project with a total height of approximately 540 m. The accuracy of the simplified model is validated through a comparison of the results of modal analyses, static analyses, and dynamic time history analyses using the refined FE models. Subsequently, the plastic energy dissipation of different components and the distribution of the total plastic energy dissipation over the height of the two design schemes are compared using the proposed simplified model. The analyses indicate that the fully braced scheme is superior because of its more uniform energy distribution along the building height and the large amount of energy dissipated in the replaceable coupling beams, which enables rapid repair and re-occupancy after an earthquake. In contrast, the potential damage in the half-braced scheme is more concentrated and more severe, and the damage in the core tubes is difficult to repair after an earthquake.

“…In order to make the proposed steel link beams coordinate in concrete coupled shear wall structures, connection between coupling beams and walls should be well designed and detailed. Most researches to date focus on the method of embedding a certain length of link beams into the concrete walls (Park et al 2005(Park et al , 2006Fortney et al 2007), as indicated in Figure 21(a). Also, there is another kind of connection detail in which structural steel columns could be embedded in the wall boundary elements and connected with the steel link beams with moment connections, as shown in Figure 21(b).…”

The performance of buildings in seismic zone is usually more complicated than that in non-seismic zone. The buildings are not only required damage-limited for fully operational after frequent earthquakes, but collapseprevented under rare earthquakes for life safety. Therefore, the buildings in seismic zone require the structure to bear proper stiffness and load-bearing capacity to resist frequent earthquakes, and possess proper ductility and energy-dissipating capacity to prevent collapse due to rare earthquakes as well. Structural metal damper is herein defined as a combination of structural member and energy-dissipating damper. It not only provides stiffness and strength to guarantee the operation of buildings under frequent earthquakes, but also dissipates energy to reduce seismic response to a considerable extent for the purpose of collapse-prevention. Three different structural metal dampers, including buckling-restrained brace (BRB), buckling-restrained steel plate shear wall (BRSW) and steel link elements, are introduced in this paper. BRB is not only a structural brace, but innovatively kept from buckling by using restrainers and its hysteretic curve is improved to be spindle-shape, ideal for dissipating energy to against seismic effects. BRSW is also ideal spindle-shape in hysteretic curve feature and can be used as an excellent structural metal damper. And in order to improve the performance of traditional shear walls and coupled shear walls under earthquakes, steel link elements are introduced. Finally, examples of using various structural metal dampers for buildings in seismic zone are presented. KEYWORDSStructural metal damper, buckling-restrained brace, buckling-restrained steel plate shear wall, steel link beam, buckling-restrained steel link wall.
