APPLICATION OF THE PRE-STRESSED CONCRETE BOX-GIRDER WITH CORRUGATED STEEL WEBS IN BRIDGE ENGINEERING IN CHINA

The pre-stressed composite box-girder with corrugated steel webs is a new kind of structure, which includes corrugated steel webs, external prestressed cables and shear connectors that connect the corrugated steel webs and the concrete flange slabs. In this paper three pre-stressed composite box-girder bridges with corrugated steel webs in China are introduced from 2007, Design experiences about the bridges are summarized, and their constructions are discussed. It has provided the beneficial reference for the later similar project. More attention should be given to this kind of structure by bridge engineers so that it can be widely used in the bridge engineering in China.
