摘要
本文根据144个拉拔试件的试验结果,探讨了变形钢筋与陶粒混凝土的粘结锚固性能,在综合分析的基础上,通过试验统计回归建立了南粒混凝土粘结强度的计算公式,并通过可靠度分析给出了钢筋的设计锚固长度,可供修订《轻骨料混凝土结构设计规程》和工程设计时参考。
in this paper, the bond-anchorage properties of deformed bars in concrete have been studied on the basis of the pull-out test of 144 specimens. By way of experimental statistical regression and comprehensive analysis, the calculating formula of bond-anchoring strength has been established. The design of anchoring length has been proposed through the reliability analysis. This may serve as a reference for revising the L.C. Structure Design Code and be used in engineering practice.
