摘要
分析了预应力框架结构中侧向约束对连续框架梁中预应力值的影响 ,以及这种影响对竖向构件本身的影响 ,提出了侧限系数的计算公式。并通过工程实例 ,提出了考虑侧向约束影响的应用条件 ,可供设计参考。
The authoor analyses the effect that the lateral restraints in frame structures acts on continuous beam.And then how the effect will influence the vertical component itself is also analysed in this paper. At the same time the computation formulas for influence index of lateral restraints are presented. Based on the analysis of numerous practical projects, the condition of lateral restrain worked is put forward.
