通过CFRP约束预压混凝土棱柱体的轴压试验,研究了在不同预压力下的CFRP加固预压混凝土棱柱体试件与CFRP加固未预压混凝土棱柱体试件,测得CFRP加固后的极限应力值,并与混凝土棱柱体试件的应力值进行了对比分析,分析了CFRP加固混凝土棱柱体的破坏特征,为实际工程的加固提供了试验依据.
通過CFRP約束預壓混凝土稜柱體的軸壓試驗,研究瞭在不同預壓力下的CFRP加固預壓混凝土稜柱體試件與CFRP加固未預壓混凝土稜柱體試件,測得CFRP加固後的極限應力值,併與混凝土稜柱體試件的應力值進行瞭對比分析,分析瞭CFRP加固混凝土稜柱體的破壞特徵,為實際工程的加固提供瞭試驗依據.

Through the test of 42 prisms under axial compression, the ultimate stress of CFRP restrained concrete with different preloading is tested,then compared it with nonpreloaded samples.The main aspects of the research includes the performances contrast on experimental study of CFRP-confined preloaded concrete prismy against unpreloaded or unpreloaded confined by CFRP.The character of breakage about concrete pris-my confined by CFRP is analyzed, and provides the experiments normally for actual engineering.
