“…The results showed that compared with other energy dissipation devices, viscoelastic dampers had better performance in reducing seismic damage. In contrast, Aydin et al [15] considered the effect of soil-structure interaction in the optimal design of cohesive dampers and applied a damper optimization method based on the target damping ratio and interlayer displacement ratio from the literature to a building structure model considering different types of sandy soils. The firstand second-order modal responses were considered separately using the time-distance analysis method, and the results showed that the negative effects of sandy soils on the dynamic performance of the superstructure could be overcome by optimizing the dampers in the buildings.…”

Based on the excellent performance of shear metal dampers in building seismic capacity, the traditional shear metal damper was optimized. A double-sided shear steel tube damper with simple structure, easy replacement, and wide application is proposed. In order to study the influence of different design parameters on its seismic performance, taking the steel tube length, height, width, thickness, and connection mode as variables, five groups of 15 specimens were designed for experimental research, and the failure modes, characteristic loads and displacements, hysteretic curves, skeleton curves, stiffness degradation curves, and energy dissipation capacity of each specimen were analyzed in detail. The test results showed that the hysteretic curves of each specimen were full and that the energy dissipation capacity was good. The greater the thickness of the steel tube was, the greater the load-bearing capacity of the damper and the larger the hysteresis loop area were. The greater the width of the steel tube was, the greater the equivalent stiffness was. As displacement amplitude increased, the equivalent stiffness of the specimen showed a downward trend. The two connection modes had their own advantages and disadvantages, and a damper with reasonable connection form would need to be selected according to actual engineering needs.

A new method of robust damper design is presented for elastic-plastic multi-degree-of-freedom (MDOF) building structures under multi-level ground motions (GMs). This method realizes a design that is effective for various levels of GMs. The robustness of a design is measured by an incremental dynamic analysis (IDA) curve and an ideal drift response curve (IDRC). The IDRC is a plot of the optimized maximum deformation under a constraint on the total damper quantity vs. the design level of the GMs. The total damper quantity corresponds to the total cost of the added dampers. First, a problem of generation of IDRCs is stated. Then, its solution algorithm, which consists of the sensitivity-based algorithm (SBA) and a local search method, is proposed. In the application of the SBA, the passive added dampers are removed sequentially under the specified-level GMs. On the other hand, the proposed local search method can search the optimal solutions for a constant total damper quantity under GMs' increased levels. In this way, combining these two algorithms enables the comprehensive search of the optimal solutions for various conditions of the status of the GMs and the total damper quantity. The influence of selecting the type of added dampers (oil, hysteretic, and so on) and the selection of the input GMs on the IDRCs are investigated. Finally, a robust optimal design problem is formulated, and a simple local search-based algorithm is proposed. A simple index using the IDRC and the IDA curve of the model is used as the objective function. It is demonstrated that the proposed algorithm works well in spite of its simplicity.

The performance of simultaneous application of steel cantilever damper and Shape Memory Alloy (SMA) rods in the reinforced concrete (RC) shear wall was investigated. In this regard, the critical numerical validation of three full-scale experimental models were distinctly performed and the results were analyzed. Various aspects of numerical modelling, including material modelling assumptions, behavioural models, elements, and solution methods were compared with experimental results. Specimens considering SMA rods as well as steel cantilever damper were numerically investigated. The results illustrated that with increasing the SMA rod angle, the maximum force was decreased, and the residual displacement and dissipated energy was improved. Also, comparing the specimen results without the SMA rods and the specimen with the SMA rods showed that despite the positive effect of the SMA rods, which leads to an increase in maximum force and reduction of residual displacement, the dissipated energy was decreased.
