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 ：
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.

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 ：
In an industrial building, heavy equipment can be configured as the mass of multiple tuned mass dampers with large mass ratio (LMTMD) without the addition of extra mass. This paper systematically investigates the effects of the LMTMD for the mitigation of structural seismic responses in industrial buildings such as a coal-fired power plant. A detailed design method was proposed based on numerical modeling, optimization of the key parameters and evaluation of the seismic performance of the structure. Shaking table tests were conducted on a scaled model and time-history analysis were performed with general purpose finite element program ABAQUS. The coal-fired power plant with mass irregularity due to the installation of heavy coal buckets was selected as the sample structure. The heavy coal buckets are utilized as the mass of the LMTMD. The feasibility and effectiveness of the proposed design method were demonstrated through tests and analyses. The simulation results agree well with the test results, which validate the accuracy of the numerical analyses and suggest that the LMTMD can effectively reduce the structural dynamic response and significantly improve the seismic performance of the thermal power plant structure. The reduction rate of the maximum inter-story drift was more than 32.6% under earth-quake excitations, demonstrating the effectiveness and strong robustness of the LMTMD. The failure mode of the structure was optimized by the reduced damage concentration.
