摘要
基于规范中对线性阻尼器支撑刚度的计算方法,结合前人研究成果,采用能量等效的方法,对非线性黏滞阻尼器的最小刚度做了计算,并就一工程中常用的一人字型支撑减震子结构为例,采用大型有限元分析软件SAP2000对其进行了研究与分析,结果表明:计算得出的非线性黏滞阻尼器支撑刚度可以使得阻尼器较为充分的发挥耗能作用,可以用于实际工程中非线性阻尼器支撑刚度的确定,为后续非线性黏滞阻尼器大的的进一步研究奠定了基础。
This article is based on the specification of linear damper brace stiffness calculation method, combining previous research results, USES the energy equivalent method, the minimum stiffness of the nonlinear viscous damper to do the calculation, and it is commonly used in the engineering one font support damping substructure, for example, using large-scale finite element analysis software sap2000 to the research and analysis, The results show that the calculated supporting stiffness of nonlinear viscous damper can make the damper fully play the role of energy dissipation, and can be used to determine the supporting stiffness of nonlinear viscous damper in practical engineering, which lays a foundation for the further study of nonlinear viscous damper.
