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 ：
消能减震技术通常需要在多个楼层布置减震装置才能有效降低结构的地震响应,占用了较多的结构空间。针对此种问题提出在底部楼层布置负刚度阻尼装置的减震方案,形成力学上的隔震层,用减震实现类似隔震的效果,以减少阻尼器的布置数量。为实现该减震方案,研发了一种基于氮气弹簧的负刚度摩擦阻尼装置,该装置具有行程大,力学性能稳定等优点。性能试验验证了负刚度摩擦阻尼装置可以实现具有负刚度特征的滞回模型,对负刚度摩擦阻尼装置布置于底部楼层的减震方案进行了模拟分析,结果表明仅在底层布置负刚度阻尼装置可以获得理想的减震效果。

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.
