摘要:

通过对54个预应力螺旋钢筋(简称PC钢棒)粘结锚固试件的拉拔试验,分析了PC钢棒的粘结锚固特点和影响粘结强度的主要因素,在统计回归的基础上给出了粘结强度的计算公式,并根据现行<混凝土结构设计规范>(GB50010-2002)提出PC钢棒的锚固长度计算公式.

Abstract:

Through the pull-out test of 54 prestressed spiral steel bars (referred to as PC steel bars) bonding anchoring specimens, the bonding and anchoring characteristics of PC steel bars and the main factors affecting the bonding strength were analyzed, and the calculation formula of bonding strength was given on the basis of statistical regression, and the anchorage length calculation formula of PC steel bars was proposed according to the current < concrete structure design code > (GB50010-2002).
