基于多尺度模型的抗震混合试验方法研究

为了从不同视角下分析结构的抗震性能，将多尺度的思想应用到结构的抗震分析中，形成集宏观计算单元、微观计算单元和试验单元为一体的多尺度抗震混合试验方法。以三层四跨Benchmark模型为研究对象，AOM(ABAQUS、OpenFresco、MTS)混合试验系统为平台，建立多尺度混合试验模型进行抗震试验分析。试验结果表明AOM混合试验系统具有较强的稳定性和较高的试验控制精度。并从试验结果中对结构进行宏观、微观层面进行分析，对结构的抗震性能分析提供了一种方法。

Research on seismic hybrid simulation based on multi-scale model

In order to analyze the seismic performance of the structure from different perspectives, the multi-scale idea is applied to the seismic analysis of the structure, leading to a multi-scale seismic hybrid test method of integrating the macro computing element, the microscopic computing element and the experimental element. Based on the AOM (ABAQUS, OpenFresco, MTS) hybrid test system, the three-layer and four-span benchmark model is established as a multi-scale model for the seismic test analysis. The test results show that the AOM hybrid test system has strong stability and high accuracy of test control. Based on the test results, the structure is analyzed at the macro and micro levels, and a method for the seismic performance analysis of the structure is provided.
