Research on Diaphragm Reinforcement Design of Continuous Composite Girder Bridge with Corrugated Steel Webs

Abstract:

Diaphragm distributes lateral loads, and improves mechanical properties of bridge structure of prestressed concrete (PC) continuous wide girder bridge. The role of diaphragm is more prominent in composite wide girder bridge with corrugated steel webs, which stiffness is smaller compared with PC continuous bridge. Diaphragm is calculated and analyzed of composite box-girder bridge with corrugated steel webs, and reinforcement schemes are presented, aimed at diaphragm crack width overrun and insufficient bearing capacity. The reinforcement scheme is adding prestressed steel cables and special supports, stress and crack resistance are analyzed on reinforced diaphragm to verify the existing problems can be completely solved.
