摘要
从平面框架结构入手 ,通过试验分析 ,对比研究了有粘结和无粘结预应力混凝土结构在不同温度、不同荷载、不同预应力度及不同张拉应力下的火灾反应。研究了预应力混凝土结构在火灾中的特性 ,提出了提高预应力混凝土结构抗火性能的一些建议。
Based on model test,comparing researches have been done on the response of bonded and unbonded prestressed concrete plane frame structure on fire under different temperatures,different loads,different prestressed reinforcement bars contents and different prestressed conditions.The characteristics of prestressed concrete structures under fire burning are discussed,and some suggestions for improving fire resistance of prestressed concrete structure have been given.
