本文以某建筑工程为背景,通过建立二种框架结构模型:无楼梯模型和整体现浇板式楼梯模型,运用中国建筑科学研究院PKPMCAD工程部研制开发的多层及高层建筑结构空间有限元分析与设计软件SATWE,对结构进行整体分析.对比分析了二种模型框架结构构件内力和主要参数指标的变化,总结出楼梯构件在地震作用下对框架结构产生的影响.并给出在结构设计中楼梯应采取的一些构造措施.
In this paper, a construction project as the background, through the establishment of two kinds of frame structure model: non-staircase model and the overall cast-in-place staircase model, using the China Academy of Building Research PKPMCAD Engineering developed multi-storey and high-rise building structural space finite element analysis and Design software SATWE to analyze the whole structure.Considering the changes of the internal forces and the main parameters of the two kinds of model frame structural members, the paper summarizes the influence of the staircase members on the frame structure under the action of the earthquake.The stairway Some constructive measures should be taken.
