| 中文摘要: |
| 某国际金融中心超高层建筑共113层,结构高度423m。首先,利用SAP2000软件建立结构的有限元模型,通过基于C#语言开发的导航式接口程序TJU.SAP2ABAQUS将SAP2000模型转换为ABAQUS模型。然后,依据规范进行7°多遇、基本和罕遇地震作用下的弹塑性时程分析。最后,模拟了超大震作用下该超高层结构的破坏过程。结果表明,(1)不同强度地震作用下结构的层间位移角均能满足规范限值要求。(2)罕遇地震作用下,结构满足大震不倒的抗震设防要求且有较高的安全储备。(3)超大震作用下,结构竖向刚度变化位置是结构潜在的薄弱部位,在抗震设计时应给予重点关注。 |

| The 113-story international financial center super high-rise building is 423m of structural height.Firstly,the finite element model of the structure was established by SAP2000 software.The SAP2000 model was converted to ABAQUS model by the TJU.SAP2ABAQUS interface program developed by C# language.Then,the elasto-plastic time-history analysis under frequent,basic and rare earthquakes of intensity 7 were carried out.Lastly,failure progress of the super high-rise structure due to extremely strong earthquake was simulated.The results indicate that,(1) The maximum inter-story drift ratios are less than limited values of code under different earthquake intensities; (2) The super high-rise structure can meet the requirements of no collapse under rare earthquake and has relatively large safety margin; (3) Changes in the position of structural vertical stiffness are potential weak parts due to extremely strong earthquake,so it should be given priority attention in the seismic design. |
