CFRP加固构件锚固端加强处理的有限元分析

Finite element analysis on the anchor end enhancement processing of CFRP reinforcement member

以梁柱角节点为例,在梁端顶部碳纤维锚固段粘贴钢板,并向外延伸在转角处向柱旋转90°包裹混凝土,并在适当位置设置钢箍或螺栓,用有限元对其进行了分析,比较了钢板厚度,钢板有无转角,锚栓位置等情况对锚固性能的影响,并给出了一些建议。

Taking the beam-column angle node as example, the author pastes steel plate on the carbon fiber anchorage section of the beam-column top, prolongs to outside and parcels concrete rotating 90 degree to the column on the corner, and sets steel hoop or bolt on suitable place, gets analysis based on the finite element, compares the influences of factors on anchor performance, such as the thickness of the steel plate, steel plate angle and anchor place, and provides some suggestion.
