基于混凝土损伤塑性模型的桥墩地震响应分析
|
摘要
为确保桥梁结构在强震作用下的安全,对钢筋混凝土桥墩进行了地震响应分析。基于损伤因子建立混凝土损伤塑性模型,考虑混凝土材料在动力荷载作用下的损伤演化,并利用损伤塑性模型对钢筋混凝土桥墩进行地震响应分析,同时分析了损伤塑性模型中膨胀角等参数对桥墩地震响应的影响。分析表明:混凝土损伤塑性模型能够较好地模拟混凝土构件在动力荷载作用下的损伤发展,所以在钢筋混凝土桥墩动力分析中应采用损伤塑性模型描述混凝土材料力学性能。
To analyze the seismic response of reinforced concrete(RC) bridge pier,a plastic-damage model for concrete is established based on damage factors.The evolution of concrete damage under dynamic load is considered.In addition,the influence of model parameters such as dilation angle on the seismic response of RC bridge pier is analyzed.It's found that the damage evolution of RC bridge pier under earthquake action can be better simulated through plastic-damage model,which,therefore,could be adopted to describe mechanical properties of concrete in the dynamic analysis of RC bridge pier.
