摘要

贵州省博物馆新馆位于贵阳市金阳新区观山公园东北角,外形较为特别,既存在平面不规则,也存在竖向不规则,还有分夹层结构以及大的悬挑,内部局部存在大跨等,为超限复杂结构。为了验证其抗震性能,故通过分析能力较强的分析软件sap2000对结构进行罕遇地震下弹塑性时程分析,以证明结构可以达到预定的性能目标。分析表明该结构能满足大震不倒的设防要求。计算方法和结论对运用有限元软件分析复杂超限建筑有借鉴意义。
The New Museum is located in the northeastern corner of Guanshanhu Park,Guiyang Jinyang New District,Guizhou Province,a more particular form,there was not only irregular plane,there are also vertical irregular planes,there are sub-sandwich structure and a large cantilevered,existing within the local span,etc.,to overrun the complex structure.In order to verify the seismic performance,it will adopt the analysis software sap2000 to analyze the antiquake ability in rare earthquake on the structure under elastic-plastic time-history analysis to demonstrate that the structure can achieve the desired performance goals.Analysis shows that the structure can not be brought down to meet the earthquake fortification requirements.Calculation method and conclusion of using finite element software of complex structure has some significance for later research.
