以一个典型的6层框架结构为算例,对纯框架结构和安装有墙式支撑软钢剪切板阻尼器的消能框架结构进行了Pushover分析。通过Pushover分析结果的对比,在研究采用墙式支撑软钢剪切板阻尼器对框架结构抗震性能的影响的基础上,重点探讨了阻尼力对框架梁受力性能的影响。研究发现,采用墙式支撑软钢剪切板阻尼器可以有效地提高框架结构的抗震能力,但是通过墙式支撑传递的阻尼力对框架梁靠近连接部位的抗弯性能和抗剪性能会产生不利影响。
Taking a typical 6-story frame structure as an example, Pushover analysis was performed on the frame structure of pure frame and the energy dissipating frame with wall-mounted mild steel shear plate damper. Based on the comparison of Pushover analysis results, the influence of damping force on the behavior of frame beam is discussed based on the study of the influence of wall-supported mild steel shear plate damper on the seismic performance of frame structure. It is found that the use of wall-supported mild steel shear plate dampers can effectively improve the seismic capacity of the frame structure, but the damping force transmitted through the wall support will adversely affect the flexural and shear properties of the frame beam near the joint influences.
