阻尼器对仿古建筑节点力学性能影响研究
Influence of damper on mechanical properties of pseudo-classic architecture joint
摘要
Abstract
[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 lintel-column 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 pseudo-classic architecture can be markedly improved by the viscous damper.关键词
