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 ：
为研究钢框架结构阻尼支座楼梯的抗震性能,设计并制作缩尺比例为1∶2的阻尼支座楼梯和固定支座楼梯试验模型,在恒定轴力作用下对其分别进行拟静力试验。试验中研究了不同楼梯的破坏形态、滞回性能、耗能性能、变形能力等,分析了不同楼梯的工作机理。试验结果表明:阻尼支座楼梯通过阻尼支座耗能,改变了楼梯的传力途径和内力分布,而固定支座楼梯通过构件自身损伤耗能,破坏阶段固定支座楼梯的平台板、斜梯梁节点和梯梁等变形较大,框架梁屈曲严重导致不能继续加载;两种楼梯的滞回曲线都较为饱满,阻尼支座楼梯加载初期刚度较小,后期其刚度达到甚至超过固定支座楼梯,有较好的承载能力;阻尼支座水平方向滑动位移较大,有利于阻尼器发挥作用...

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.
