平面钢框架结构简化为双翼鱼刺型振动模型的研究
|
摘要
对于平面钢框架结构,应用非线性静力分析法,借助于增值系数λ,提出了新的结构振动模型——双翼鱼刺型振动模型.然后选取5个结构算例,利用4种方法确定结构刚度矩阵后,采用3组地震波加速度时程离散值进行了地震响应弹性时程分析,验证了其合理性.该模型由于考虑到梁刚度对结构整体刚度的影响,比质点系剪切型振动模型具有很多优越性,不仅在弹塑性范围内能够得到精度较高的结果,而且具有输入数据简单、计算简便的特点,可为结构抗震工程计算和设计提供简便而有效的一种解析手段.
This paper analyzes planar steel-frame construction by nonlinear static procedure,and proposes a new kind of structure model called dual wings fishbone-shaped model with the aid of the incremental coefficient λ.Then the model′s rationality is confirmed by three earthquake waves to calculate the seismic response of five examples via elastic time-history analysis after determining stiffness matrix via four kinds of methods.Comparing with the shear model,the new model has many advantages because it considers the influence of the beam stiffness in the holistic structure stiffness.It not only can obtain high accurate results in the scope of elastic-plastic stage,but also has many advantages,such as easy input data and simple calculation.The model can provide an easy and effective analysis method for engineering calculation and design of structure under earthquake.
