由于FRP包裹混凝土柱能够显著提高柱的抗压强度 ,杂交柱已成为土木工程修复加固领域的新热点。但复合材料只有在混凝土的横向变形较大时 ,才能发挥应有作用。如何使高强复合材料和混凝土更好地协同工作 ,充分发挥两者的特性 ,就成为制约杂交柱结构应用的一个关键问题 ,给复合材料施加预应力无疑是解决这一问题的有效方法。针对预应力杂交柱利用增量法提出了新的分析模型 ,进行了参数分析 ,得出了适用于预应力杂交柱的计算方法 As the FRP wrapped concrete column can significantly improve the column compressive strength, hybridization column has become a new hot spot in the field of civil engineering repair and reinforcement. However, the composite material can play its due role only when the transverse deformation of the concrete is large. How to make high-strength composite materials and concrete work better together, give full play to the characteristics of the two has become a key problem restricting the application of hybrid column structure. Prestressing composite materials is undoubtedly an effective way to solve this problem. For the prestressed hybridization column, a new analytical model was proposed by incremental method, and the parameters were analyzed. The calculation method suitable for prestressed hybridization column
