摘要
波纹钢腹板预应力混凝土梁桥是对传统的预应力混凝土梁桥的一次重大改进。首先,用波纹钢腹板代替混凝土腹板,大大降低了自重;此外,采用波纹钢腹板就避免了平钢腹板中通常都要布置的加劲肋。结合国外已有的分析成果和实桥资料,对波纹钢腹板粱的力学性能,包括波纹钢腹板的剪切屈曲和波纹钢板梁的弯曲强度进行了介绍和分析。
The prestressed concrete beam bridge with corrugated web has greatly improved the traditional prestressed concrete beam bridge. First of all, the replacement of concrete web with corrugated steel web has greatly reduced its dead weight. Besides, adopting corrugated steel web can save the stiffening ribs, which usually need to be added in flat steel web. Combined with the achievements in analyses abroad as well as the data of actual bridges, the mechanics performance of corrugated steel web beam has been introduced and analyzed including the shear bend of corrugated steel web and the bending strength of corrugated steel beam.
