由截顶正八面体构成的多面体空间折板结构是一种新型的结构体系。通过采用Midas/gen和SAP2000对结构模型进行动力性能的分析,得到结构的自振特性,对结构模型进行振型分解反应谱法和弹性时程分析,研究结构在多遇地震作用下的抗震性能。对结构进行动力弹塑性时程分析和比较,研究结构在罕遇地震作用下的抗震性能,从而得到一些有用的结论。
The truncated octahedral polyhedron space flap structure is a new type of structural system. By using Midas / gen and SAP2000 to analyze the dynamic performance of the structure model, the natural vibration characteristics of the structure are obtained. The vibrational decomposition response spectrum method and the elastic time history analysis of the structure model are carried out to study the seismic performance of the structure under the action of frequent earthquakes . The dynamic elasto-plastic time-history analysis and comparison of the structure are carried out to study the seismic performance of the structure under rare earthquakes, and some useful conclusions are obtained.
