Steel pipe dampers offer advantages such as a simple structure, low cost, high energy absorption and dissipation, consistent functionality under cyclic loading, and ductility. Dual-pipe dampers show improved performance over single pipe dampers in terms of strength. The current study focused on the structural performance of the dual-pipe system. The seismic performance of steel-framed structures having 4, 8, or 16 stories with either a simple moment frame or a braced frame equipped with pipe dampers were subjected to seismic loading and investigated using the finite element method. The performance of the models was examined by considering the base shear and lateral displacement of the roof as well as the von Mises distribution. The stress distribution caused by the plastic damage concentration increased in the pipe dampers in the 4- and 8-story models and the base shear decreased 50% in the 4-story models equipped with a pipe damper. The results showed that, in the 16-story models, the strength in the damping system should be designed in accordance with the other elements. In addition, the strength of the damping system can be increased by increasing the number of pipes and their thickness.

钢管阻尼器具有以下优点：结构简单，成本低廉，能量吸收和耗散高，在循环载荷下功能一致，延展性好。就强度而言，双管阻尼器的性能优于单管阻尼器。当前的研究集中在双管系统的结构性能上。对具有4、8或16层高的钢框架结构的抗震性能进行了地震荷载作用，并使用有限元方法进行了研究，这些钢结构具有简单的弯矩框架或装有管道阻尼器的支撑框架。通过考虑屋顶的基础剪力和侧向位移以及冯·米塞斯分布来检验模型的性能。在4层和8层模型中，由塑料破坏集中引起的应力分布在4层和3层模型中的管道阻尼器中增加，而基础剪力下降了50％。结果表明，在16层模型中，阻尼系统的强度应根据其他要素进行设计。另外，可以通过增加管道的数量和厚度来增加阻尼系统的强度。
