摘要:
通过对7根不卸载的混凝土梁进行预应力CFRP布加固后的荷载试验,研究了不同的初始弯矩对构件受弯性能的影响和作用.试验研究表明,初始弯矩的存在使构件的受弯性能明显降低,并且随着初始应力水平的增加,降低作用更加明显.
Abstract:
Load experiments of seven concrete beams strengthened with prestress CFRP sheets when load is not removed have been carried out. This paper researches mainly that different initial moment has the influernce and action on the character in bending of member.The experiments show that the existing of initial moment weakens clearly the character in bending,and with the increasing of initial stress,the effect is more notable.
