An algorithm for the calculation of bridge curve in UG;

In this paper the gridiron method is used to analyze 3 spans and 4 spans curved bridge which use same height web plate and different height web plate,and the better cross-section is chosen by each section’s index of steel and its stiffness.

Along with the development of transportation and civilization in our country, a lot of curved bridges have been widely applied in the high way and overpass.

Analysis of the supports of curved bridges;

The proposed model is simple, yet it captures essential features that affect the dynamic response of curved bridges.

Research purposes: Curve parallel arrangement method is a commonly used method for design of railway bridge,especially for the curve bridge crossing highway and river,but is generally used for small span bridge,so the research is done in this paper on application of this method in large span curve bridge for the purpose of enlarging the application scope of this method based on the example.

Research purposes:For the peculiar crankle coupling mechanics peculiarity of the curve bridge that the structure internal force is quite intricacy.

This paper discussed the disease causes of the curved beam bridges.

Based on the APDL programming technique,a fundamental procedure of developing a constructed prestressed concrete curved beam bridge simulation program is developed.

Two methods about how to calculate the bearing off-center of curved beam bridge are presented,which is common but no conclusion now.
