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 软件建立结构整体模型,并对结构分析相应地震作用下的抗震性能。结果表明,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。
英文摘要:
      Take one project as an example, the structure with large span floor with dense rid beam stress performance was analysed. The building structure with local ribbed beam forming large span floor, in order to achieve the requirements of large space building. In this paper, the seismic response characteristics of the structure are analyzed, and the structure calculation and comparison are carried out by using the method of mode decomposition response spectrum method and elastic dynamic time history analysis method. Using MIDAS/GEN software to establish the overall structure model, and to analyze the seismic performance of the structure under seismic action. The results show that the dense rib floor on the overall structure of the seismic characteristics have a greater impact, the story changes is an important factor to affect the performance of the structure.
