摘要:

基于转动摩擦铰阻尼器(RFHD),提出了转动摩擦耗能干式装配梁-柱节点(DRFDBJ)。为了验证DRFDBJ结构对于实现预期力学性能的可行性和合理性,以施加在摩擦片表面的螺栓预紧力(P_c)为变量,开展了2个工况下的DRFDBJ试件低周往复拟静力试验研究。结果表明:DRFDBJ结构的力学性能主要由RFHD提供并控制,试验中节点呈现了稳定的承载力和理想的变形、耗能能力,并实现了预期的损伤集中; 2个不同P_c水准下节点承载力的试验值与理论值误差不超过5%,通过调整P_c可实现节点承载力的调控,为DRFDBJ结构承载力的可调控提供了支撑。

Abstract:

Based on rotational friction hinge damper(RFHD),the dry-connected rotational friction dissipative beam-to-column joint(DRFDBJ)is proposed.Such a joint is expected to feature a good energy-dissipation capacity,adjustable performance as well as concentrated damage.To validate the feasibility and rationality of the DRFDBJ for achieving the expected mechanical performance,two load cases of pseudo-static cyclic experimental tests are carried out.The pre-tension force applied on the surface of the friction pads(P_c),which is a critical parameter of DRFDBJ,is selected as the test variable.The results indicate that the mechanical properties of DRFDBJ are mainly provided and determined by RFHD.Stable strength,stable deformation and energy dissipation capacities are exhibited in the tests.The expected damage-concentration feature of the joint is achieved.The errors between the experimental value and the theoretical value of the joint bending moment strength with two P_c- values are not more than 5%.The strength of DRFDBJ could be adjusted by varying P_c-value,thus laying a foundation for the strength adjustment of DRFDBJ.The results could serve as a reference for relative investigations on dry-connected precast concrete structures and frictional energy dissipation devices.
