基于Park三参数模型的剪切滞变模型
|
摘要
针对深梁、短柱和剪力墙等剪跨比较小的构件在结构非线性分析中需要考虑剪切效应的情况,在Park三参数滞变模型的基础上,参考大量文献后,建议了短柱、剪力墙和核心筒三种构件的剪力-剪切变形曲线本构关系特征点的参数取值,给出了剪跨比较小构件的剪切滞变模型。采用该模型分别对短柱、剪力墙和核心筒三个试验模型进行了模拟和分析,分析结果与试验结果的对比表明,所给模型可较好地模拟试件的剪切效应及实际抗剪承载力水平。该模型的建立可为结构非线性分析中有效考虑剪切效应提供参考。
The shear effect on the member with short shear-span ratio(deep beams,short columns and shear walls etc.) in nonlinear response analysis of structures needs to be considered.On the basis of Park three-parameter hysteretic model and referring to a lot of references,the parameter values of characteristic points on the skeleton curve of shear force-shear deformation relationship of deep beams,short columns and shear walls are suggested.Thus the hysteretic shear models of these members with short shear-span ratio are given.The model is used to analyze three test models of deep beam,short column and shear wall,respectively.Comparing the calculation results with that of test,it shows that the shear effect and actual shear force could be properly simulated by the model presented in this paper.The establishment of the model provides a reference to considering shear effect in structural nonlinear analysis effectively.
