“…Buildings which have been built before 1981 and especially before 1971 went through severe damages to such an extent that some of them collapsed. It suggests that old provisions concerning designing of buildings have not properly considered seismic loads, as well as structural flexibility [9].…”

Steel shear walls are a novel component in the field of construction. It has been of special interest to structural engineers for the reinforcement of steel buildings for the recent decades. Its unique features have attracted more attention, and its features are economical, easy to implement, light weight compared to similar systems, high ductility, fast installation, high energy absorption, and a significant reduction in residual stress in the structure. All the reasons made researchers think about studying its use in the repair of concrete buildings. Because this system has a low weight, it does not add extra load to the structure, and even with its connections, it strengthens the beams and columns around it. The design of this system in concrete buildings does not seem to be economical except in the case of restoration. In this paper, preliminary explanations of the steel shear wall are presented for more familiarity, and in the following sections, the study of reinforcement and repair of concrete structures will be studied and its difference with the low-yield point will be considered. Finally, the test results will be reviewed. The results of this study show that LYP steel shear panels cause a lot of energy loss and absorption, which is very useful in the safety of buildings exposed to severe earthquakes.

Summary In this paper, a new shape memory alloy (SMA) damping device named confined superelastic dissipator (CSD) was examined. The proposed dissipator consists of a fused superelastic nickel‐titanium (NiTi) SMA bar as the functional kernel component encased in grout‐filled steel tube. The bar carries the axial load and dissipates energy through axial deformation while the steel tube and infill grout restrain the bar and precludes buckling in compression. First, theoretical derivations for the design of the buckling restraining system were discussed. Then, the hysteretic behavior of CSDs was investigated through cyclic quasistatic tests. A total of eight specimens were designed, fabricated, and tested. All specimens exhibited stable and flag‐shaped hysteretic behavior with excellent self‐centering characteristics. Response quantities of prime interest for earthquake engineering such as energy dissipation, equivalent viscous damping, and self‐centering capability were evaluated. The effect of geometric parameters such as fuse diameter and bar length on these parameters as well as failure mechanisms of CSDs was studied. Based on the experimental results and visual observations of failed specimens, specific recommendations were made to improve the performance of the CSDs.

“…The high demand for structural reinforcement to improve the seismic-resistant performance of existing buildings has been heightened, to reduce damage and risk against earthquakes in the near future, because of the lack of seismic-resistance capacity. Various methods are used for the seismic retrofitting of existing buildings; installations of viscous dampers, hysteresis dampers, or reinforcing frame members are the general construction methods for a seismic retrofitting (Wang and Zhao, 2018;Kazantzi and Vamvatsikos, 2020). A base isolation system is also adopted for seismic retrofitting of structures (Matsagar and Jangid, 2008;Cardone and Flora, 2016).…”

The seismic responses of a single-story reinforced concrete (RC) frame building model under control using an active mass damper (AMD) are demonstrated through a real-time hybrid simulation (RTHS) method. In this study, the RTHS test is carried out by using a hydraulic actuator and a shaking table under synchronization. Most parts of the target RC frame model are provided as an analytical model for an online computer simulation, and only the single column of the first story is prepared as an experimental substructure. A hydraulic actuator deforms the actual RC column, and uncertainty or nonlinearity of the RC column's behavior is focused on in this RTHS test. At the same time, a control device of AMD is actually tested under a situation of installing it on the target building's floor. The floor response of the target building model is generated using a shaking table . A control motion of the AMD is manipulated based on an online simulation of the entire RC building model. Firstly, a time delay compensation of the hydraulic actuator is considered. Time delay parameters are identified using a combination model of a time lag and a first-order delay. A PID controller and a time series compensator are applied to improve actuator performances. Next, the reproducibility of the RTHS test using two-individual actuators is evaluated. The tracking of a restoring force and deformation of the actual RC column specimen generated by the hydraulic actuator and floor motion responses reproduced on the shaking table are investigated. To improve the online numerical simulation based on the measured force responses of the RC column specimen, a high-pass filter (HPF) is applied for a force correction to utilize its phase-lead property. The effect of this HPF force correction is evaluated in both a linear region and a strong nonlinear region of the actual RC column specimen. Finally, the RTHS test results are compared to fully numerical simulations and the control effect of the AMD to increase the damping effect for the target RC building model is also investigated.
