摘要
依据预应力锚固损失分析中的反摩阻影响机理,结合模拟空间曲线预应力筋的非均匀B样条曲线参数方程,推导出预应力锚固损失的数值计算公式,该公式适用于任意空间曲线型预应力筋,并适合编程计算。
Base on the principle of anti-friction impact in anchorage loss of prestress tendons and simulation of space-curved presressing tendons aided by Non-Uniform B-Splines. a numerical formula to calculate anchorage loss of 3D presressing tendons are proposed in this paper, which also suits programming.
