| 中文摘要: |
| 以工程为例,分析带有大跨度密肋楼盖结构的受力性能。该建筑结构局部采用密肋梁形成大跨度楼盖,以实现建筑的大空间要求。文中着重分析了结构的地震反应特性,通过振型分解反应谱法和弹性动力时程分析方法进行结构计算和比较。利用 MIDAS/GEN 软件建立模型,对结构模型进行竖向荷载和地震作用下的受力分析。从计算结果比较来看,密肋楼盖对整体结构抗震特性有较大影响,层高的变化是影响结构性能的重要因素。同时,对结构设计提出一些建议和意见。 |
| 英文摘要: |
| This thesis takes one project as an example and analysis the structure with large span floor with dense rid beam stress performance . The example"s structure is frame structure. In the middle space of it, the dense rid beam can be seem as a component for high-rise buildings. This thesis analyzes the stress characteristic of large span floor with dense rid beam structure. The mode-decomposition spectrum response analysis and elastic dynamic time-history analysis are carried out. The building structure have built model by MIDAS/GEN software and have been analyzed in the situation of vertical loads and seismic loads and will be analyzed and calculated the mechanical properties. At the same time, we have put forward some advices to the structure design. |
