摘要
以有限元方法为理论基础,借助于大型通用有限元软件ANSYS,利用Beam4单元及Shell63单元建立符合实际情况的框架模型,施加季节温差,并将混凝土收缩折算成温差作用,分析框架结构变形、梁柱内力、板中的应力大小和分布的变化规律,并提出混凝土框架结构设计建议。
The finite element method as the theoretical basis, by means of large-scale finite element software ANSYS, using Beam4 unit and Shell63 element to establish the framework for realistic model, imposed seasonal temperature and converted into thermal shrinkage effect of frame deformation, beam column internal forces, board size and distribution of the stress variation, and propose concrete frame design proposals.
