针对采用连续通长布置、分段搭接布置及局部重叠布置三种预应力筋布置方式对预应力混凝土框架考虑侧限影响的计算模型差异，建立了连续通长布置预应力筋的单层多跨框架侧限影响系数计算公式，提出了分段搭接布置预应力筋及局部重叠布置预应力筋时侧限影响的分析方法，为应用预应力混凝土结构设计的经典方法和统一方法解决复杂结构的侧限影响问题提供了参考．

英文摘要：

Based on calculation model difference in prestressing tendon disposal of continuous all length, overlapped subsection and tensioning subsection and overlapped partially span, calculation formulae of lateral restraint modulus for one - storey ＆ multiple - span prestressed concrete frame with continuous all length tendon are proposed. The method to analyze effects of lateral restraint for one - storey ＆ multiple - span prestressed concrete frame with overlapped subsection and tensioning subsection and overlapped partially span are presented. All these make it possible to apply traditional method and unified method of design prestressed concrete structures to solve the problem on the effects of lateral restraint in complied structures.
