基于可靠度的FRP加固混凝土结构研究综述
|
摘要
通过对现有FRP材料力学参数概率分布、FRP加固混凝土结构可靠度、荷载-抗力分项系数表达式及相关分项系数取值等研究现状的回顾,表明现阶段FRP材性参数概率分布多为经验性假设,FRP加固混凝土结构在不同破坏模式下的可靠度研究尚不全面,同时相关分项系数取值差异性较大,且未经严谨的可靠度检验。为进一步完善基于概率极限状态理论的FRP加固混凝土结构设计理论,本文建议了后续进一步研究的工作内容。
A critical review of the-state-of-the-art researches was addressed on the probability distribution of FRP mechanical property,reliability of concrete structure strengthened with FRP,load and reisitence factor expression and the reduction factors including resistence reduction factor and material strength reduction factor and so on.It is indicated that probability distribution was experience assumptions,reliability of strengthened structures were not comprehensive,and then the relative reisitence factor have been adapted from those in the design codes for steel reinforced concrete structures without reliability calibration. In order to make the research work more systematic and reasonable,some suggestions and furture research works based on reliability theory were put forward.
