摘要:
混合配筋预应力混凝土管桩(PRC)是在先张法预应力混凝土管桩(PC)基础上,采用预应力钢棒与非预应力普通钢筋间隔对称布置而形成的一种新型预应力管桩,本文在受弯刚度模型试验的基础上,采用通用有限元软件对混合配筋预应力混凝土管桩的抗弯刚度进行了计算分析,通过比较开裂前刚度和开裂后刚度的有限元计算值、试验值和按现行混凝土规范公式的计算值,提出了适应于混合配筋管桩的开裂前和开裂后抗弯刚度的理论计算公式.
Abstract:
The prestressedand reinforced concretecompoundedpipe pile(PRC)is anewtype ofprestressing pipe pile，formedby the symmetrical arrangement of prestressing steel bars and non-prestressed reinforcment，on the basisof pre—tensioned prestressed concrete pipe piles(PHC)andhigh strength prestressedconcrete tu· bular pile．Finally，a computational analysis of the stiffness of the prestressed and reinforced concrete conpounded pipe pile using finite elementsoftware are introduced，by comparing the before—cracking stiffness and after．cracking stiffness of the finite element calculated values，experimental values and calculated values according to the existing concrete specification formula，a theoretical formulais proposed to calculate the before。cracking and after cracking flexural rigidity．
