摘要:
螺旋肋钢丝(简称PC棒)是我国新研制开发的用于顸应力混凝土结构的新型钢丝.通过对28个先张法构件端部区域混凝土应变的量测,分析了PC棒预应力传递长度范围内混凝土应变和应力的变化规律以及主要影响因素,提出了PC棒预应力传递长度计算公式的建议,为PC棒的工程应用提供了依据.
Abstract:
his paper presents the results of transmission length tests on 28 pre—tensioned members made ofprestressing reinforcement with helical rib(PC steel bars)．The compressive strain and stress of concrete with—in the prestressing transm ission zone for the PC steel bars of the members are analyzed，and the factors affect—ing the transmission length of PC steel bars in concrete are also discussed，and a formula for calculating thetransmission length is suggested．The result can provide reference for the application of PC steel bars in con—crete strueture．
