摘要
介绍了波形钢腹板预应力混凝土(PC)组合箱梁桥中波形钢腹板的设计方法,给出了中国在建和已建的该类桥梁结构中波形钢腹板的抗剪屈曲界限图,总结了中国在这种桥梁中所使用的几种抗剪连接件形式,并介绍了2种新型的抗剪连接件及2007年以来中国在建的4座波形钢腹板PC组合箱梁桥的结构及其特点,为今后这种结构的桥梁建设提供了有益的参考。
The design method for the corrugated steel webs of the prestressed concrete （PC） composite box-girder bridge was introduced. The shear buckling boundary chart about corrugated steel webs in this type of bridge structure was worked out which included constructed and being built bridges in China in recent years. Some kinds of shear connectors which were used in bridges building in China were summarized, and two kinds of new shear connectors were introduced. The structures and characteristics of four PC composite box-girder bridges with corrugated steel webs being built in China since 2007 were introduced in order to provide the beneficial reference for the construction about this kind of bridge in the future.
