摘要

摘要: 在试验研究的基础上,对化学植筋单向拉拔试验的破坏模式进行讨论,对引起植筋锚固系统破坏的5个因素混凝土破坏、钢筋破坏、粘结剂破坏、混凝土与粘结剂之间的界面破坏和钢筋与粘结剂之间的界面破坏进行归纳。根据混凝土、钢筋和植筋胶等各种介质的特点及其粘结滑移关系,提出植筋锚固系统的有限元分析模型,对介质单元和界面粘结单元的处理方法予以介绍,并编制相应的计算程序。电算结果表明,计算结果与试验结果吻合较好。

Abstract: Based on experimental research, the failure modes of adhesive anchorage system resist to pullout load are discussed. The failure of adhesive anchorage system can be derived from 5 factors: concrete failure, steel failure, adhesive failure, adhesives and concrete interface failure as well as steel and adhesive interface failure. Based on the features of different media in adhesive anchorage system, such as concrete, steel bar, adhesives, and bond-slide relationships between them, a finite element model for the analysis of multi-media system is proposed. A computer program is developed, whose result shows taht the calculated result coincides well with the test result.
