【摘要】 粘贴碳纤维增强塑料加固混凝土桥梁结构是近年来开始在交通领域应用的新技术。以平截面假定为基础的力学模型较好地描述经过预应力碳纤维布加固的受弯构件的工作性能,并进行构件试验,证明利用碳纤维增强塑料加固受弯构件可有效提高受弯构件的极限承载能力,并对裂缝开展的抑制产生有效的约束作用。更多还原

【Abstract】 Bonding CFRP to strengthen reinforced concrete bridge structures is a new technology in transportation engineering. This paper presents a analytical model, which is based on strain compatibility to describe the behavior of beams strengthened with CFRP. Tests of beams reinforced with CFRP indicate that bonding CFRP can significantly increase the ultimate load and restrain cracking of the beam.更多还原
