CFRP-PCPs复合筋加固钢-混组合梁负弯矩区抗裂试验与理论计算OA北大核心
Experimental and theoretical calculation of cracking resistance in the negative moment zone of steel concrete composite beams strengthened with CFRP-PCPs composite reinforcement
为解决钢-混组合梁负弯矩区混凝土板易开裂而造成刚度减弱的行业难题,以预制的CFRP-PCPs(carbon fibre re-inforced polymer-prestressed concrete prisms)复合筋作为中支座的腹筋,并以复合筋的数量、预应力张拉水平和截面尺寸为主要参数设计制作了五根复合筋钢-混组合连续梁和一根普通组合连续梁,研究其在单跨单点荷载下负弯矩区的抗裂性能.结果表明:复合筋能显著增强中支座截面刚度,对负弯矩区的裂缝…查看全部>>
In order to overcome the industry problem that the concrete slab in the negative moment region of the steel-concrete composite beam is prone to cracking causing weakening of stiffness.Prefabricated CFRP-PCPs(car-bon fiber reinforced polymer-prestressed concrete prisms)composite reinforcement is used as the web reinforcement of the middle support.Five steel-concrete composite continuous beams with composite reinforcement and one ordina-ry composite continuous…查看全部>>
