摘　　要：【目的】为研究黏滞阻尼器对仿古建筑的力学性能的影响,通过设置仿古建筑梁-柱节点来开展试件的对比试验研究。【方法】设计制作了6个仿古建筑梁-柱节点,即3个双梁-柱节点及3个单梁-柱节点,并对其施加正弦波往复荷载以研究其一系列力学性能,主要包括荷载-转角滞回曲线、骨架曲线、承载能力、变形性能、耗能能力等。【结果】在整体上,黏滞阻尼器对双梁-柱节点力学性能的改善程度比对单梁-柱节点的更为显著,且改善程度随黏滞阻尼器型号不同而不同。在附设黏滞阻尼器后,梁-柱节点试件的滞回曲线更饱满,承载能力提升了16.4%~32.9%,位移延性系数增大了1.5%~12.6%,耗能能力提升了49.2%~112.3%。【结论】黏滞阻尼器可显著改善仿古建筑梁-柱节点的力学性能。[Purposes]In order to study the influence of viscous dampers on the mechanical properties of pseudo-classic architecture,a comparative experiment for lintel-column joint specimens of pseudo-classic architecture was carried out.[Methods]Six lintel-column joints of pseudo-classic architecture were designed and produced,including three dual-lintel-column joints and three single-lintel-column joints,and their mechanical properties were studied by applying reciprocating sinusoidal wave loads,such as the load-angle hysteresis curve,skeleton curve,load carrying capacity,deformation capacity,and energy dissipation capacity.[Findings]Overall,the improvement degree of viscous dampers on the mechanical properties of dual-lintel-column joints is more significant than that of single-lintel-column joints,and the improvement degree varies with the type of viscous dampers.After the viscous damper is installed,the hysteresis curve of the lintelcolumn joint specimens is fuller;the load bearing capacity is increased by 16.4%-32.9%;the ductility coefficient is increased by 1.5%-12.6%,and the energy dissipation capacity is increased by 49.2%-112.3%.[Conclusions]The mechanical properties of lintel-column joints of pseudoclassic architecture can be markedly improved by the viscous damper.
