Analysis of segmental bridge built by balanced cantilever method

[Catjacob]

Hello bridge guys,

I'm going to assess a 20 years old post tensioned bridge of which the concrete deck was cast in-situ with travelling gantry attached to cantilever ends.

My question is, after 20 years have gone, is the creep induced by the weight of the gantry still "significant"? I mean is it still necessary to consider the weight of gantry in estimating the creep effect?

Thanks,

J
