摘要:
为获得自复位摩擦耗能支撑模型的合理参数,以自复位摩擦耗能支撑的MFS模型为研究对象,研究MFS模型在低周期往复位移加载下参数的敏感性,给出参数合理的取值范围,采用CKF算法在线识别MFS模型参数。结果表明,利用模型参数敏感性分析得到的参数取值范围分别为0<b<3.5 mm、K>0、0<Q<1、0<A<1。CKF算法可以有效在线识别模型参数,识别结果能够反映模型真实滞回性能。
Abstract:
This paper intends to achieve reasonable parameter values of self-centering energy dissipation(SCED)braces model. The achievement is made possible by investigating the sensitivity of parameters of MFS model under low cycle reciprocating displacement loading by taking the MFS model of the SCED as the research object; defining a reasonable parameter value range; and ultimately identifying MFS model parameters online using CKF algorithm. The results show that the sensitivity analysis of model parameters enables the value range of parameters of 0<b<3.5 mm, K>0, 0<Q<1 and 0<A<1. respectively. CKF algorithm allows for an effective online identification of model parameters, giving the recognition results reflecting the real hysteretic performance of the model.
