The influence of lateral restraints on the prestressed concrete structure has been discussed in many papers and main factors including the style of structures,stiffness ratio of column to beam and method of construction are considered except the distribution of effective prestress.
改变柱梁的线刚度比、摩擦系数进行计算分析发现,侧向约束影响系数将随着梁柱线刚度比的减小而减小,随着摩擦损失的增大而增大;忽略有效预应力的分布得到的结果与实际情况有偏差,这种偏差随着梁柱线刚度比的减小而增大,随着摩擦损失的增大而增大,因此预应力作用受侧向约束的影响应考虑有效预应力的分布。

补充资料：单轴各向异性
单轴各向异性是磁晶各向异性的最简单形式，即自发磁化的稳定方向（或易磁化方向）平行于一特殊晶轴。如六方晶系钴的自发磁化方向平行于 C轴(见晶体结构)，这就表现出强的单轴各向异性。磁性材料的单轴各向异性值一般都低于其磁晶各向异性值，为103erg/cm3量级。磁性材料经磁场热处理或强的冷加工而产生的感生各向异性，都属于单轴各向异性。
