本文通过对预应力混凝土电杆试件的试验,探讨了预应力混凝土环形截面偏心受拉构件的强度和抗裂度等问题.对几种计算方法作了比较,并提出了建议的计算公式. In this paper, through the test of prestressed concrete poles, the strength and cracking resistance of the prestressed concrete eccentrically-tensioned tensile members are discussed. Several calculation methods are compared, and the proposed formula is proposed.
