【摘要】 提出了预应力混凝土结构后张拉应力测试方法，并以方舟综合楼预应力板面后张拉试验结果为依据，对后张拉预应力结构在张拉过程中的应力传递、摩擦阻力的影响及应力的损失等问题进行了分析探讨，得到了一些有益的结论．更多还原

【Abstract】 A testing method of stress for post tensioned steel strands in pre-stressed concrete is proposed. Based on the testing results of Fangzhou building, it is analyzed that the stress transfer in the course of tensing, the effect of friction resistance, and the reduce of stress etc.. At last, some useful conclusions are obtained.更多还原
