摘要
通过对4根后张部分预应力混凝土轴拉构件的试验研究,对部分预应力混凝土轴拉构件的受力特性、裂缝展开及闭合的机理进行了理论分析;对“闭合荷载”进行了理论推导,文末就裂缝闭合在工程设计中的应用进行了探讨。
In this paper,the character of tension stress and mechanism of crack opening or closing are studied,based on the experimental study of four post tensioned axial tension members.Besides,the formula of “Crack Closing Load”is proposed.Finally,the application of crack closing in engineering is discussed.
