摘要
预应力将在超静定结构中产生次内力.在具有任意曲线形状的预应力筋和沿预应力筋纵向具有任意分布的预应力所产生的杆单元固端次内力计算积分表达式的基础上,探讨了固端次内力计算程序的设计方法,可为工程设计计算提供快捷而有效的工具.
Prestress will cause secondary internal force in statically indeterminate structures. Based on the formula of calculating the secondary internal force at the fixed end of prestrese - element due to pre-stressing with any initial shape of prestressing cable and any distribution of prestress along the cable, a programming method has been discussed which provides a direct and effective means for design and compution.
