【摘要】：基于缩尺模型子结构混合模拟试验方法,将正态分布随机数引入测量误差,利用MATLAB和Open SEES混合编程技术,分别对剪切型模型、弯剪型模型进行了考虑测量误差的子结构混合模拟数值模拟分析。数值模拟结果表明:在满足JGJ/T 101—2015《建筑抗震试验方法规程》的误差范围内,缩尺比为1/2、1/4缩尺模型的测量误差与足尺模型相应测量误差基本相当。在缩尺比例不小于1/4情况下,随着地震峰值加速度增大,总的累积相对差值呈增加趋势;在相同地震峰值加速度作用下,总的累积相对差值随梁柱线刚度比增加呈减少趋势。通过1/2钢框架子结构混合模拟试验,验证了所提出的缩尺模型子结构混合模拟试验方法的精准性和可行性。
[Abstract]:Based on the method of scale model substructure mixed simulation test, the normal distribution random number is introduced into the measurement error, and the shear model is analyzed by using MATLAB and Open SEES mixed programming technology, respectively. The substructure mixed simulation numerical simulation analysis considering measurement error is carried out. The numerical simulation results show that, within the error range of JGJ/T 101-2015 < Code of aseismic Test methods for Building], The measurement error of the scale ratio of 1 / 2 / 1 / 4 scale model is basically equivalent to that of the full scale model. When the scale ratio is not less than 1 / 4, the total cumulative relative difference tends to increase with the increase of the peak acceleration of the earthquake. Under the same earthquake peak acceleration, the total cumulative relative difference tends to decrease with the increase of Liang Zhu's linear stiffness ratio. The accuracy and feasibility of the proposed method are verified.
