异形柱框架节点受力性能分析

Analysis for the Joint of Concrete Special-shaped Columns

钢筋混凝土异形柱结构在我国住宅建设中得到了广泛的采用,而对于异形柱节点在荷载作用下的性能至今仍没有完全理解,介绍了异形柱节点的受力特征以及顶层角节点的一般受力性能,运用有限元分析软件对异形柱角节点进行有限元非线性分析。研究异形柱节点从加载到开裂的过程,以及各个阶段钢筋和混凝土的应力分布情况,为今后对于异形柱的分析计算奠定了基础。

Reinforced concrete special-shaped columns used in residential construction in recent years,for their unique qualities,the users widely welcome and have been gained a wide development.The performance of whose joints cannot be completely understood under the load regarding the complexity until now.At the same time whose stress characteristic and influence factors have been specially discussed so with the general stress performance of beam-column knee joints on top story.Whose stress characteristic and influence factors have been specially discussed with the general stress performance of beam-column knee joints on top story.Nonlinear analysis is carried on to study the process of dehiscence of beam-column knee joint,as well as stress distribution of rebar and concrete on each stage,and laid the foundation for the next analysis for frame with special-shaped column.
