摘要
粘结型钢加固技术是一种新型的加固方法,在建筑物改造与加固工程中,当梁高不受限制时,能大幅提高梁的极限承载力,解决粘结钢板可能带来的超筋问题;粘胶和植筋能保证型钢和钢筋混凝土梁共同工作。详细论述了型钢-混凝土组合梁的计算原理和方法,并以王英水库工作桥结构的加固为例,说明了型钢-混凝土组合结构在结构改造加固中的优越性,提出此方法在建筑改造加固中具有广泛的应用前景。
Bonding profile steel can largely improve the ultimate bearing capacity of existing beams and slabs in the rebuild and strengthened engineering of the buildings when the beam height is not limited. This paper presents the calculation method of section steel-concrete composite beams in detail and taking Wang Ying reservoir working bridge as example the superiorities of this composite structure as well as its the wide application prospect in reconstruction and reinforcement work of buildings are elaborated.
