钢筋混凝土框架柱层间屈服位移角的影响因素分析
|
摘要
收集了国内外181根钢筋混凝土矩形截面柱的抗震性能试验数据,由于各试验因素取值存在差异或缺失,无法直接采用传统的拟合回归方法得到层间屈服位移角与各因素之间的关系。为了将次要因素偏差的影响控制在一定程度,本文提出了一种改进的数据过滤处理方法,并利用编制的程序对每个区间的数据点进行过滤,从而使各区间剩余数据点的次要因素均值尽可能处于同一水平。根据过滤后剩余的数据点,分别探讨了轴压比、纵向配筋率及剪跨比对框架柱层间屈服位移角的影响规律。结果表明,框架柱的层间屈服位移角随轴压比的增大而线性减小,随纵向配筋率的增大而线性增大,而受剪跨比的影响较小。
The seismic performance test data of 181 reinforced concrete columns with rectangular section both at home and abroad are collected,but the relationship between the yield drift angles and influencing factors couldn't be obtained by using the traditional fitting regression method directly because of the differences or missing of secondary factors.In order to eliminate some of the secondary factor bias effects,an improved data filtering processing method is presented and the compiling program is used to filter some data for each interval,which tried to make the secondary factors means of remaining data points in each interval at the same level.According to the filtered data points,the influence of axial compression ratio,longitudinal reinforcement ratio and shear span ratio to the yield drift angles of reinforced concrete columns are discussed respectively.The results show that the yield drift angles of frame columns decrease linearly with the increase of axial compression ratio,and they increase linearly with the increase of longitudinal reinforcement ratio,but the effect of shear span ratio is smaller.
