Abstract ：
The traditional ideal elasto-plastic hysteresis model performs well in controlling structural displacement, yet its effectiveness in controlling acceleration is often suboptimal. The force equilibrium relationship of a single-degree-of-freedom (SDOF) system reveals that the structural acceleration response is closely related to the damping force at peak displacement. Based on this, a notched bilinear hysteretic model was proposed to make the damping force zero at peak displacement. The displacement and acceleration responses were compared with those of a traditional ideal elasto-plastic model by slowly varying the SDOF parameters to obtain steadystate results. An algorithm for the proposed hysteretic model was established using MATLAB, its integrated control effect on the displacement and acceleration responses of the SDOF was verified by a nonlinear time history analysis, and its optimal control interval and parameters were obtained. A damping device was subsequently developed based on the characteristics of the notched bilinear hysteretic model and its feasibility and mechanical properties were verified through experimental studies. The results showed that a well-designed notched bilinear hysteretic model can effectively control structural displacement while achieving effective control of the acceleration response, thus enabling dual control of both structural displacement and acceleration.

Abstract ：
In this study, the antiwhip capability of high-energy piping in nuclear power plants was investigated based on the basement structure of a conventional island in a nuclear power engineering project. A lead extrusion impact damping device was developed, and its mechanical performance was validated through uniaxial static loading tests. A 1:4 scaled-down test model was designed and fabricated using traditional energy-dissipating steel beams, lead extrusion impact damping, and concrete blocks as three types of antiwhip restraining devices. Impact test studies were conducted supplemented by destructive impact tests without antiwhip restraining devices. Finite element models were established using Ansys LS-DYNA simulation software, and simulations were conducted for these four scenarios. The antiwhip performances of different antiwhip measures were evaluated by comparing the test and finite element simulation results and considering factors such as the impact force, wall displacement, wall acceleration, and crack distribution and development. The results indicate that while traditional energy-dissipating steel beams continue to provide some antiwhip effectiveness, the lead extrusion impact damping solution exhibits a significantly improved performance with better control of the structural dynamic response. In contrast, the concrete block solution demonstrated a poorer performance, leading to severe damage in structures like those without antiwhip restraining devices.

Abstract ：
A cold-formed steel shear wall with centre-corrugated steel sheathing (CCSS-CFS shear wall) was innovatively developed to meet the requirement of earthquake resistance for multi-rise CFS structures in regions at high seismic risk. This wall exhibits superior seismic performance in comparison with the conventional CFS shear wall. Five full-size specimens were tested under cyclic loading to evaluate their failure mode, shear strength, lateral stiffness, ductility, energy dissipation, as well as degradation of bearing capacity and stiffness. Additionally, the effects of CFS frame structure forms, screw spacing, and corrugated steel sheet thicknesses on the behaviour and failure mechanism of shear walls were analysed. The seismic performance objectives corresponding to intact, slight, moderate, and severe damage were also determined. The results revealed that the main failure modes of shear walls were plastic buckling of corrugated steel sheathing and local buckling of the end composite stud. Optimising configurations such as setting up stiffening plates on the end composite stud, installing transverse braces, and increasing screw spacing between composite studs and sheathing significantly improved their behaviour. The strength of corrugated steel sheathing after plastic buckling should be taken into consideration for the lateral design of the CCSS-CFS shear wall. A calculation method was also proposed in order to determine the elastic global buckling shear strength of the CCSS-CFS shear wall - which exhibited high accuracy. Finally, nominal shear strength, a resistance factor, and a safety factor were recommended.

Abstract ：
A passive double triangular damping (DTD) device with equivalent negative stiffness is proposed in this study. The DTD device consists of transmission systems and triangular damping systems. A mechanical model was developed to describe the force-displacement relationship of a triangular damping system, while the feasibility of both the system and model was evaluated using experimental tests. The theoretical analysis demonstrated that DTD was a form of damping with equivalent negative stiffness, and the equivalent expressions were generated. Finally, the prospect of application in the DTD-controlled isolation system was explored using numerical simulation. The results revealed that DTD was more effective than a lead-rubber bearing in reducing isolator displacement and rooftop acceleration when subjected to ground motions.

Abstract ：
In order to study the seismic performance of stairs in steel frame structures, two 1:2 scaled test models of stairs with damped supports and fixed supports were designed and manufactured, and the quasi-static tests were carried out under constant axial force. The failure modes, hysteresis performance, energy dissipation performance and deformation capacity of different stairs were investigated, and the working mechanism of different stairs was analyzed. The test results show that the energy dissipation of the staircase with damped supports is through damping effect, which changes the way of force transmission and internal force distribution of the staircase. The energy dissipation of the staircase with fixed supports is through the damage of the component itself. In the stage of failure, the deformation of the platform plate, the joint of the inclined beam and the staircase beam of the staircase with fixed supports is large, and the severe buckling of the frame beam causes the failure of bearing capacity. The hysteretic loops of the two stairs are full and plump. The stiffness of the stairs with damped supports is smaller in the initial stage of loading, but later reaches or even exceeds that of the stairs with fixed supports, indicating better bearing capacity. The horizontal sliding displacement of the damping support is larger, which is beneficial to the damper, and the vertical displacement can be neglected. The vertical stiffness of the damping support effectively controls the warping of the pedal. © 2021, Editorial Office of Journal of Building Structures. All right reserved.

Abstract ：
A new type of eccentric wheel layered friction damper was proposed in order to solve a series of problems induced by the excessive pressure needed for the normal friction damper. To achieve the goal of obtaining proper damping force under a smaller pressure, parallel multilayer friction plates were adopted. What's more, a pressure device with eccentric wheels was designed to get a variable friction function and to keep the pre-pressure on the friction surface of the damper at 0 during the standby stage of the service period so as to improve the reliability of the damper and solve the problem of excessive pressure. The performance of the damper was studied through reciprocating load tests. The relation between the damping force and the displacement of the eccentric wheel layered friction damper was obtained, and the mechanical properties of the eccentric wheel layered friction damper were analyzed with finite element method. The results show that the layered design of friction damper can effectively enlarge the friction damping force. The theoretical and finite element simulation results are in good agreement with the experimental results, which shows the results can be used as references for the design of dampers. © 2021, Editorial Office of Journal of Vibration and Shock.

Abstract ：
A new type of negative stiffness friction damping device (NSFDD) was developed in this study, which can solve the problem of poor energy dissipation of the existing passive negative stiffness damping device. The friction force is generated by squeezing the friction plate with the preloaded nitrogen spring vertically. When the NSFDD is working, the friction plate causes the nitrogen spring to rotate and negative stiffness force and friction force are generated. The results of the performance test show that the NSFDD can achieve negative stiffness in the hysteretic model. Comparing with the existing negative stiffness device, the NSFDD has larger stroke, more stable negative stiffness and better energy dissipation capacity. The finite element software has been used to simulate the low cycle reciprocation of a structure, and the results show that the NSFDD reduces the stiffness of the structure while increasing the damping of the structure. The results of the simulation and analysis of the shock absorption plan of the NSFDD show that the NSFDD reduces the stiffness of the floor, thereby effectively control on the shear force, displacement and acceleration response of the structure.
