摘要

为解决针对复杂土木工程结构地震易损性评估中精度与参数不确定性的问题，本文提出考虑地震动与结构自身参数的双重不确定性的混合试验易损性评估方法。该方法将拉丁超立方采样与正交设计相结合选取地震动-结构模型参数样本对，在充分考虑双重不确定性的基础上，有效地减少样本数量；利用模型更新混合试验获取结构地震响应数据，得到考虑双重不确定性的结构易损性曲线。通过对6层带有自复位摩擦耗能支撑的钢框架结构进行混合试验虚拟仿真，验证所提方法的有效性。研究结果表明：与数值模拟、平方根容积卡尔曼滤波算法（ square root cubature Kalman filter，SRCKF）在线模型更新混合试验方法相比，采用统计SRCKF算法进行模型更新能够有效地提高数值子结构的模型精度，虚拟混合试验结果均方根误差更小，易损性评估精度高；采用拉丁超立方采样与正交设计相结合的方法能够有效地减少样本对的数量，并充分地考虑地震动与结构模型参数的双重不确定性；本文所提出的方法可为结构地震易损性评估提供有效手段。

Abstract

To address the issues of accuracy and parameter uncertainty in seismic vulnerability assessment of complex civil engineering structures, this paper proposes a hybrid experimental vulnerability assessment method that considers the dual uncertainty of seismic motion and structural parameters. This method combines Latin hypercube sampling with orthogonal design to select sample pairs of seismic structural model parameters, effectively reducing the number of samples while fully considering dual uncertainty; Using model updating hybrid experiments to obtain structural seismic response data, a structural vulnerability curve considering dual uncertainty is obtained. The effectiveness of the proposed method was verified through hybrid experimental virtual simulation of a 6-story steel frame structure with self resetting friction energy dissipation support. The research results indicate that compared with numerical simulation and square root cubature Kalman filter（SRCKF） online model updating hybrid testing methods, using statistical SRCKF algorithm for model updating can effectively improve the model accuracy of numerical substructures. The root mean square error of virtual hybrid testing results is smaller, and the accuracy of vulnerability assessment is higher; The combination of Latin hypercube sampling and orthogonal design can effectively reduce the number of sample pairs and fully consider the dual uncertainty of seismic motion and structural model parameters; The method proposed in this article can provide an effective means for evaluating the seismic vulnerability of the structure.
