工字型钢铅组合耗能器减震体系的优化设计研究
|
摘要
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 combined steel-lead damper(CSLD) with the merits of a simple principle,a simple production process and an economic performance can take the advantages of steel and lead so as to absorb energy from earthquakes.The optimization design of I-section combined steel-lead dampers in a structure control system is studied.A civil engineering vibration control Benchmark structure simulation model is established,and the parameter of the ratio of a damper-yield force to an inter-story yield-shear force is introduced to analyze vibration reduction effect.The calculated results show that the system has the best effect when the ratio is 5%.According to the optimization design method,the structure control system of a steel frame model is designed and conducted in a shaking table test,and the test result indicates that the combined steel-lead damper control system has an excellent vibration reduction effect,and it verifies the reasonability of the optimization method.
