Abstract text:
In this paper, some aspects concerning the design of steel-concrete composite footbridge structures are presented. The steel girders are built-up as rolled sections with circular holes in webs. In the design of the footbridge structure besides the ULS and the SLS verifications, also the comfort criterion has to be verified which is in direct correlation with the structure frequency (risk of resonance) and acceleration.
Key Words:
footbridge structures; composite girders; traffic comfort; ULS and SLS verifications
