钢铅组合耗能器能够利用钢和铅两种材料耗散能量,具有原理简单、制作方便和价格低廉等优点。该文针对一种工字型钢铅组合耗能器在减震体系中的设置优化进行了研究。建立了土木工程减震控制Benchmark结构的仿真模型,为工字型钢铅组合耗能选取了合理的模型,以耗能器屈服力与结构层间屈服力比值为参数,进行减震效果分析。计算结果表明屈服比为5%时,结构减震效果较好。依据优化设计方法对一栋钢框架模型进行了减震体系设计,并进行了模拟地震振动台试验,试验结果表明钢铅组合耗能器减震体系达到了较好的减震效果,说明了该文建立的钢铅组合耗能器减震体系优化设计方法的合理性。
The steel-lead combination energy dissipater can utilize the two materials of steel and lead to dissipate energy, has the advantages of simple principle, convenient manufacture and low price. In this paper, the design and optimization of a type I-shaped steel-lead combination energy dissipater in shock absorption system was studied. A simulation model of the Benchmark structure of the damping control for civil engineering was set up, and a reasonable model was selected for the energy consumption of the I-shaped steel-lead combination. The damping effect was analyzed by taking the ratio of the yield strength of the energy absorber and the yield strength of the structural layer as the parameter. The calculation results show that the damping effect of the structure is better when the yield ratio is 5%. Based on the optimal design method, a steel frame model was designed and the seismic shaking table test was carried out. The experimental results show that the damping system of the steel-lead combination energy dissipator achieves a better damping effect, The Rationality of Optimized Design Method of Vibration Reduction System for Steel - Lead Combined Energy Dissipator.
