| 摘 要： | 研究了钢纤维增强混凝土中纤维和基体之间的粘结力特性与拉伸本构关系.首先根据其受力特点提出了几点假设条件,建立了以τ-s曲线和统计理论为基础的钢纤维增强混凝土直接拉伸本构关系模型,该模型考虑到了影响钢纤维增强混凝土断裂性能的基体软化特性和纤维拔出特性,同时将对粘结力特性的研究成果引入到拉伸本构模型,因而使这个模型更加符合实际性状.所得成果对钢纤维混凝土的强度分析、结构设计和工程应用有着重要意义.图3,参2.

| Abstract: | This paper deals priJunily with bond and constitutive relationship in fiber reinforced concrete.First,it provided some assumed condition based on its strained characteristic,considered the inelastic behavior of the fibre-Juntrix interface and the softening characteristics of the matrix,which are the two priJuny nonlinear aspects of the failure mechanism in SFRC.Theoretical load-deformation relations of SFRC were compared with results from experimental tests and good qualitative agreement was obtained.The results are valuable for the strength analysis,structure design and engineering application in steel fiber reinforced concrete structures.3figs.,2refs. |
