摩擦耗能支撑减震结构参数研究
|
摘要
文章系统地研究了摩擦耗能支撑(FDB)参数对多层摩擦耗能支撑结构(FDBF)减震效果的影响。以结构顶层位移、层间位移和基底剪力为减震效果评价指标,通过对大量多层FDBF模型进行地震激励下的动力时程分析,全面考察了FDB 4个重要参数——布置方式、滑移力、支撑刚度、起滑位移——对结构减震效果的影响和规律。对原结构选取减震方案,并绘出结构中各层FDB的滞回曲线,从而直观反映了FDB的耗能性能。最后,对已有的FDB参数范围进行修正和完善,建议了选取FDB参数的总原则。
We aim to reduce the seismic vibration of multi-storey friction energy dissipating braced frame(FDBF).Sections 1 and 2 of the full paper explain:(1) the calculation model of FDB,(2) the calculation model of FDBF,(3) the selection of FDB parameters,(4) the selection of FDBF parameters,(5) the selection of seismic wave.Sections 3 and 4 take a 6-story building as example and give calculated results in Fig.4 and Table 2 for three cases:(1) no FDB,(2) FDBF1 with one selection of FDB parameters,(3) FDBF2 with another selection of FDB parameters.Section 5 gives four preliminary conclusions for improving seismic suppression effectiveness of friction-energy dissipating bracing.
