STUDY ON THEORY AND PRACTICE OF DIAPHRAGM BEAM OF PRESTRESSED CONCRETE BOX GIRDER BRIDGE

摘要：

The solid model of a six-span prestressed continuous box girder bridge is built with the help of finite element program in this paper to obtain the stress state of diaphragm. Vibrational chord strain gauges are buried in the diaphragm during the construction of the bridge, the actual stress distribution form of the diaphragm can be acquired through measuring strain of embedding sensors. A practical and simplified two-step plane member system finite element method for diaphragm calculation is put forward based on the theoretical and practical research. Comparative analysis shows that this method is reliable, economical and can provide valuable reference for diaphragm design and calculation.
