摘要
根据结构安全性检测鉴定结果,对带裂缝预应力混凝土空心楼板进行了加固方案设计,提出了加固结构计算模型。对采用粘贴玄武岩纤维布加固预应力混凝土空心楼板进行了全过程计算分析。结果表明:玄武岩纤维布加固预应力混凝土板可以达到提高结构承载能力的目的。
A strengthening design of pre-stressed concrete plate with cracks is made according to results of structure diagnosis,and calculation model is put forward.Basalt fiber sheets are used to strengthen pre-stressed concrete plate and the analysis of all course is done,whose results are evaluated by calculation,which indicated that the bearing capacity of the said plate is raised.
