摘要
为了提升传统风格建筑枋-柱组合件的力学性能,本文将黏滞阻尼器与传统风格建筑相结合。共设计3个传统风格建筑枋-柱组合件模型试件,包括2个安装黏滞阻尼器的模型试件及1个未安装阻尼器的对比模型试件,对其分别施加快速谐波荷载,以获得其力学性能相关数据。试验结果表明:黏滞阻尼器与传统风格建筑枋-柱组合件协同受力,试件力学性能显著提升。设置阻尼器后枋-柱节点荷载-位移滞回曲线包围的面积显著增大;承载能力分别提升30.5%、60.1%,变形性能分别提升4.9%、15.2%,承载能力及变形性能显著改善,抗倒塌能力得到加强;试件破坏时,耗能性能分别提升80.2%,84.2%,耗能能力得到有效增强;设置阻尼器后,试件的刚度退化呈先快后慢的变化趋势,峰值后下降阶段的刚度大于对比试件。结果表明通过设置黏滞阻尼器,可显著改善传统风格建筑的力学性能。
To enhance the mechanical performance of Chinese traditional style lintel-column joints,the vis-cous dampers were integrated with Chinese traditional style architecture in this paper.Three representative lin-tel-column joint specimens were fabricated,comprising two damper-integrated specimens and one control speci-men,with harmonic loading applied to quantify their mechanical parameters.Experimental results demonstrated synergistic interactions between viscous dampers and traditional lintel-column joints,yielding significant me-chanical improvements.The hysteretic curves of the joints with viscous damper were plump.The damper-equipped specimens exhibited 60.1%and 30.5%enhancements in load-bearing capacity,4.9%and 15.2%increases in deformation capacity,and 80.2%and 84.2%improvements in energy dissipation capacity at fail-ure,respectively.Stiffness degradation in modified joints followed a rapid-to-gradual progression,maintaining superior post-peak residual stiffness compared to conventional configurations.Properly configured viscous dampers in Chinese traditional style lintel-column joints conclusively exhibit superior mechanical performance under cyclic loading conditions.
