摘要
结构模型试验虽然是一门古老的技术,但在当前结构工程领域还占有重要地位,尤其是振动台模型试验技术在检验结构抗震设计性能,探索复杂特殊结构本质特性方面起着重要作用。
     本文首先介绍了相似原理的基本理论及其发展现状和振动台模型试验的主要内容。对近年来国内外已经进行的振动台试验项目进行了系统的梳理总结,归纳出目前在振动台试验领域尚存在的一些问题,并对振动台模型试验领域未来需要继续深入研究的问题进行了初步探讨。
     通过对振动台试验中几种常用相似规律的回顾,本文针对附加任意人工质量的模型相似律问题进行深入研究,给出了以一致相似律表达的用于附加任意人工质量相似模型设计的相似律。
     以开源有限元系统OpenSees作为分析工具,本文针对一钢筋混凝土框架结构的振动台模型试验进行了系统的数值模拟研究,给出了原型结构,理想完全人工质量模型,附加40%人工质量欠质量模型及实际试验模型结构的弹性与弹塑性时程分析结果及结构的塑性发展历程,并根据弹塑性时程分析的结果探讨了结构在遭遇罕遇地震作用时的响应。
     本文根据试验实测结果与结构弹塑性时程分析结果进行了对比分析研究,试验模型实测结果与数值模拟结果吻合较好,验证了本文所采用的有限元分析模型及分析技术的正确性;根据附加40%人工质量欠质量模型的反推值与原型弹塑性有限元分析结果的比较,检验了本文所提出的用于附加任意人工质量相似模型设计的相似律的正确性与可靠性;最后通过理论分析及完全人工质量与实际试验模型弹塑性时程分析结果的对比,初步探讨了振动台试验与计算机数值模拟相互融合技术方面的问题。
As an ancient technology, structural model tests still plays an important role in the filed of structural engineering currently, especially for shaking table tests.
     This thesis addresses the dynamic similitude theory and numerical simulation of shaking table test. In particular, it focuses firstly on the similitude law of model tests supplemented with arbitrary artificial mass. Then it focuses on the nonlinear numerical simulation of shaking table test.
     Shaking table tests which had been carried out recent years were summarized. Some problems existing in shaking table tests were presented at the following contents and some problems were discussed. Further studies were placed on the similarity law about arbitrary artificial mass which then proposed a general similarity law suitable for small scale models with arbitrary artificial mass.
     Numerical simulations of a four story RC frame shaking table test model were systematically carried out. And the OpenSees (Open System for Earthquake Engineering Simulation) finite element system was adopted to do the analysis of the finite element models including prototype structure, adequate model, scaled down structure supplemented with 40% artificial mass and test model. During the finite element analysis, elastic and elasto-plastic time-history analysis were both taken.
     According to the results of elasto-plastic time-history analysis of models that encountering earthquake of seldom intensity IX, structural response were compared and evolution of structural plasticity were obtained. Reliability and correctness of the finite element analysis model adopted in this thesis were verified through comparison between test results and nonlinear numerical simulation results of test model.
     According to the comparison between numerical simulation results of prototype structure and scaled down structure supplemented with 40% artificial mass, the general similarity law proposed in this thesis were feasible and correct.
     Finally, theoretical studying and comparison between analytical results of test model and of scaled down structure were taken. Preliminary studies were placed on the integration between shaking table test and numerical simulation.
