摘　　要：为提升C型钢阻尼器的性能,以适应更高的工程需求,提出一种新型的等截面C型钢阻尼器。给出该阻尼器的设计力学公式,建立三维模型,使用ANSYS软件进行仿真分析,以获取阻尼器的性能参数,并进行室内对比试验。试验结果表明,在相同地震条件下,基于抗震阻尼钢的等截面C型钢具有更高的阻尼比和更加稳定的滞回特性,明显提高了使用效果。该研究成果可为工程实际中考虑使用等截面C型钢替代变截面C型钢提供参考。To improve the performance of C-type steel dampers and meet higher engineering requirements,a new type of constant cross-section C-type steel damper is proposed.A three-dimensional model was established for this type of damper and simulation analysis was conducted using ANSYS software to obtain the performance parameters of the damper.In addition,experimental comparative studies were conducted.The experimental results show that under the same seismic conditions,the constant section C-shaped steel based on seismic damping steel has higher damping ratio and more stable hysteresis characteristics,significantly improving the effectiveness of use.These research results could provide valuable references for considering the use of constant cross-section C-beams instead of variable cross-section C-beams in engineering practice.
