通过6根梁试件的单调加载静力试验,对有黏结预应力CFRP筋混凝土梁的受力过程、破坏形态、抗弯承载力、位移延性以及变形特性等进行了较系统的研究,并利用ANSYS软件对试验梁进行了非线性有限元分析。
6)  prestressed concrete with GFRP
预应力CFRP筋混凝土
补充资料:预应力
分子式:
CAS号:

性质:试验中试样所受到的预加的恒定静态应力,单位为Pa。在生热性疲劳试验中,如固特里奇屈挠试验中,一般都施加一恒定预应力,使试样产生一静态变形,再叠加一周期压缩变形进行试验,通常预应力的大小会影响试样的疲劳寿命,预应力越大,则试样寿命会越明显缩短。也有的先施加一静态压缩变形,再叠加周期性剪切变形进行试验。
