| Abstract: | Based on a steel truss arch bridge with a 48 m+180 m+48 m main span, the key design technique and thinking of the key joints of arch - girder junction at the middle pier and side pier are introduced. A finite element analysis model of girder - shell junction is built to verify the rationality of joint design. |
